You pick up your phone to check a route or scroll through news. Most of us think these tools just appeared by magic from a few famous names in California. We talk about the CEOs but rarely mention the people who actually wrote the code or designed the hardware. The truth is that a disproportionate number of them came from India, studied at IITs or NITs, moved to Silicon Valley, and quietly changed how billions of people interact with technology.
These people are not household names. They do not trend on social media. Corporate communications rarely spotlights them. But the products they built? You have used them so many times today you stopped noticing them entirely. Some built the systems below the interface. Some built the interface itself. And a few made tech usable for people who get ignored way too often. Here are 10 names that deserve a lot more attention
10. Ruchi Sanghvi – Facebook's First Female Engineer Who Built News Feed
Ruchi Sanghvi joined Facebook in 2005 as employee number 51 and the company’s first female engineer. She led the team that built News Feed, the feature that now defines not just Facebook but basically every social media platform that came after it. Before News Feed launched in 2006, you had to manually visit each friend’s profile to see what they posted. Sanghvi’s team created the automated stream of updates that made social media addictive, for better and worse.
Sanghvi studied computer engineering at Carnegie Mellon after growing up in Pune. She joined Facebook when it was still a scrappy startup operating out of a house in Palo Alto. Mark Zuckerberg assigned her to a project that would change everything: creating a personalized feed of friend activity. The technical problem was complex. The system had to monitor millions of actions, decide what was interesting, rank updates by relevance, and deliver them instantly without crashing servers.
News Feed launched to immediate backlash. Users hated it, created protest groups, and demanded Facebook remove it. Sanghvi and her team held firm, making privacy adjustments but keeping the core feature. Within weeks, engagement metrics proved they were right. News Feed became the template every platform copied: Twitter, Instagram, TikTok, LinkedIn. Sanghvi later led Facebook Platform, which let outside developers build apps on top of Facebook’s social graph. She left in 2010 to co-found Cove, then became a prominent Silicon Valley investor. But her legacy is that endless scroll of updates you check compulsively. She built the defining interface of social media, and did it as the only woman in Facebook’s early engineering ranks. (10)
9. Anurag Acharya – The Creator of Google Scholar
Anurag Acharya built Google Scholar in 2004, and in doing so, he democratized access to academic research. Before Scholar, finding scientific papers meant paying for expensive database subscriptions or physically going to university libraries. Acharya created a search engine specifically for scholarly literature that anyone with an internet connection could use for free. That single tool changed who gets to participate in research and education.
Acharya studied computer science at IIT Kharagpur, then earned his PhD from Carnegie Mellon. He joined Google in 2000 and started the Scholar project almost as a side endeavor. The technical challenge was massive: academic papers are scattered across thousands of publishers, universities, and repositories. Each uses different formats and metadata standards. Acharya had to build crawlers that could find papers, algorithms that could understand citations and determine relevance, and systems that could rank results by scholarly impact rather than just keywords.
Google Scholar now indexes over 200 million documents and handles millions of searches daily. Researchers in developing countries use it to access papers they could never afford otherwise. Students writing term papers rely on it to find sources. Scientists track citations to their work through Scholar profiles. Acharya’s creation leveled the playing field between wealthy institutions and everyone else. He remains a Distinguished Engineer at Google, continuing to refine Scholar’s algorithms. The academic publishing industry hates that he made their paywalled content discoverable for free, but researchers everywhere consider Scholar indispensable. Acharya gave knowledge away, and that matters more than most products Silicon Valley builds. (9)
8. Krishna Bharat – The Inventor of Google News
Krishna Bharat created Google News in 2002, fundamentally changing how people consume information. Before his invention, reading news meant visiting individual newspaper websites or relying on a single source. Bharat built an algorithm that automatically aggregates stories from thousands of publishers, groups related articles together, and presents multiple perspectives on the same event. That shift from curated to algorithmic news distribution reshaped journalism itself.
Bharat grew up in Bangalore, studied at IIT Madras, then earned his PhD in computer science from Georgia Tech. He joined Google Research in 1999. The idea for Google News came after the September 11 attacks, when Bharat found himself manually checking dozens of news sites to piece together what was happening. He wondered why a computer couldn’t do that automatically. Within months, he’d built a prototype that used clustering algorithms to identify stories and rank them by relevance and source diversity.
Google News launched publicly in 2002 and now serves over a billion users monthly. Bharat’s algorithms prioritize showing you multiple sources on important stories, which sounds simple but required solving hard problems around duplicate detection, bias mitigation, and real-time processing. He became a Google Distinguished Scientist and founded Google’s research lab in Bangalore. Publishers have complicated feelings about Google News, since it drives traffic but also commodifies their content. But Bharat’s creation changed the fundamental distribution model for journalism. You check news throughout the day instead of waiting for a morning paper, and that behavioral shift traces directly back to what he built. (8)
7. Samir Samat – Android's Top Boss
Samir Samat runs Android’s entire business operations and partnerships as Vice President at Google. Every phone manufacturer that puts Android on their devices works with Samat’s organization. Every carrier deal, every regional rollout, every partnership that puts Google services on Android phones globally goes through his teams.
Born in India and educated at Purdue, Samat joined Google in 2011. He’s responsible for Android’s expansion to over 3 billion active devices worldwide. That makes it the most-used operating system in human history, and Samat manages the commercial relationships that made it possible. When Samsung, Xiaomi, or Oppo launch new Android phones, those deals happened because of frameworks his teams built.
He also oversees Android’s relationship with developers, managing the Play Store ecosystem and the revenue sharing models that determine how app makers get paid. That directly affects which apps get built and which features developers prioritize. His decisions shape what’s possible on the phone in your pocket, yet Google’s public events focus on product managers and designers instead. (7)
6. Sabeer Bhatia – The Entrepreneur Who Created Web-Based Email (Hotmail)
Sabeer Bhatia co-founded Hotmail in 1996, creating the first major web-based email service. Before Hotmail, email was something you accessed through software installed on your computer. You couldn’t check it from anywhere else. Bhatia’s insight was simple: put the email interface in a web browser, and suddenly people can access their messages from any computer with an internet connection.
Bhatia studied at BITS Pilani, then transferred to Caltech for a degree in electrical engineering. He came up with Hotmail while working at Apple. The name was originally HoTMaiL, with the capital letters spelling HTML. The service grew explosively, hitting 8.5 million users within a year. Microsoft bought it in 1997 for $400 million, one of the largest acquisitions in tech at the time.
Hotmail’s impact is hard to overstate. It proved that software could live entirely in browsers, which paved the way for Google Docs, Slack, Salesforce, and basically every web app you use today. Bhatia’s model made software accessible without installation, ownership, or expensive licenses. That’s the foundation of cloud computing. Every time you check Gmail or access software through a browser, you’re using a paradigm Bhatia pioneered. He changed where software lives, and that changed everything. (6)
5. Manik Gupta – The Architect of Google Maps' Core Features
Manik Gupta didn’t create Google Maps from scratch, but he built the features that turned it from a basic digital atlas into the indispensable navigation tool you can’t live without. He joined Google in 2006 and spent years as the product manager and director who shaped Maps into what it is today. Turn-by-turn navigation, real-time traffic updates, offline maps, and the entire mobile experience? Those all came from teams Gupta led.
Gupta studied computer science at IIT Delhi before earning his MBA from the Wharton School. At Google, he pushed Maps beyond simple directions. He championed integrating Street View into navigation, adding business information and reviews, and building the APIs that let other apps embed Maps functionality. That last part is huge. Every food delivery app, ride-sharing service, and location-based app relies on Google Maps Platform, which Gupta helped architect and commercialize.
He also led the product strategy for Google Maps on mobile devices just as smartphones were taking off. The decision to offer free turn-by-turn navigation in 2009 basically destroyed the standalone GPS industry overnight. Garmin and TomTom never recovered. After Google, Gupta joined Uber as VP of Product, then became Chief Product Officer at Carta. but his legacy at Google is what shaped our modern world. You’ve used his product decisions to find restaurants, avoid traffic, and navigate unfamiliar cities hundreds of times. His name just never appeared on the screen. (5)
4. Sanjay Ghemawat – The Google Architect Who Built the Infrastructure Running Half the Internet
Some engineers build the product you can see. Sanjay Ghemawat built core systems that other Google products rely on. He designed Google File System and BigTable, the storage technologies that handle Google’s unfathomable scale. Every Google Search query, YouTube video, Gmail message, and Google Drive file relies on systems Ghemawat architected. He’s a Google Fellow, the company’s highest technical rank, shared by fewer than twenty people.
Ghemawat studied at IIT Kanpur, then earned his PhD at MIT. He joined Google in 2000, when the company was still tiny. The systems he built had to scale from millions to billions of users without falling apart. GFS and BigTable became the blueprint for modern distributed storage. When Amazon, Facebook, and Microsoft built their cloud infrastructures, they studied what Ghemawat had done.
His work with Jeff Dean (they’re basically inseparable in Google lore) also produced MapReduce, the data processing framework that enabled big data analytics. That technology spawned Hadoop and the entire ecosystem of tools data scientists use today. Academic papers Ghemawat co-authored have been cited thousands of times. He built the invisible infrastructure that makes the internet function at scale, and he did it while most people had never heard of cloud computing. (4)
3.Vinod Dham – The "Father of the Pentium Chip" Who Made Personal Computing Possible
He landed in the US with very little money but a lot of ambition. Most people do not know that the chip inside their first real computer came from his team. In 1993, Vinod Dham led the group that created the Pentium processor at Intel. That chip put real computing power into affordable home computers. Before the Pentium, PCs were slow, clunky machines for spreadsheets and word processing. After the Pentium, they could handle multimedia, games, and eventually the internet revolution.
Dham earned his electrical engineering degree from Delhi College of Engineering, then joined Intel in 1984. He managed the entire Pentium project, from architecture to manufacturing. The chip ran at 60 MHz (laughable by today’s standards) but represented a massive leap at the time. It made home computing genuinely useful for regular people, not just hobbyists and professionals.
After Intel, Dham held executive roles at NexGen, AMD, and Silicon Spice. He later became a venture capitalist, funding startups in India and the US. But his legacy is the Pentium. That processor’s descendants still run in computers today. The “Intel Inside” stickers that covered laptops for decades? That branding campaign launched with Dham’s chip. He made personal computing mainstream, and most people have no idea who he is. (3)
2. Ajay Bhatt – The Intel Engineer Who Invented the USB Port
Every USB cable you have ever plugged in. Every external hard drive, keyboard, mouse, phone charger, and flash drive. All of it works because of a single specification developed in the mid-1990s by a team at Intel led by Ajay Bhatt.
Bhatt was born in Vadnagar, Gujarat, studied at Maharaja Sayajirao University of Baroda, and came to the United States for his master’s degree, before Joining Intel in the 1990’s. He led the team that developed Universal Serial Bus technology (USB), which debuted in 1996. The idea was simple: one port type for everything. Execution was complex. He had to create technical standards that every hardware manufacturer would adopt, and convince an entire industry to change.
He wanted to make computers easier for regular people to use. He faced a lot of pushback because other companies wanted to keep their own plugs. But he stuck with his idea. He did not even make any money from the invention because Intel owns the patent. He just wanted to solve a common problem. Every time you plug in a cable without thinking about it, you are using his brainwork.
USB became the standard for everything. Your keyboard, mouse, external drive, phone charger, camera, and printer all use descendants of Bhatt’s design. USB-C, the latest version, can transfer data, deliver power, and connect displays through a single cable. Bhatt also worked on AGP and PCI Express, other connectivity standards that became universal. His name should be as recognizable as Edison’s. Instead, most people don’t know he exists. (2)
1. Amit Singhal: The Man Who Ran Google Search for 15 Years
From 2000 to 2016, one person held more influence over what information the world could access than almost any other individual on earth. His name was Amit Singhal, and he ran Google’s core search quality and ranking team for 15 years. He created the mathematical logic that decides which website is the best answer to your question. Think about the power of that. Every time you search for anything, his math is what gives you the answer.
Singhal grew up in Jhansi in Uttar Pradesh, studied at IIT Roorkee, and completed his PhD at Cornell. He joined Google when the company was still figuring out what it was. Under his leadership, Google’s search algorithm absorbed natural language processing, spam detection, and eventually the Knowledge Graph, which is the panel of structured information that appears when you search for a person, place, or concept.
For fifteen years, every improvement to Google’s core search product went through him. The “spell check” feature you use without thinking? That’s his team. The way Google understands that “Jaguar” might mean the animal or the car depending on context? That’s the semantic understanding his algorithms pioneered. He received the title of Google Fellow, one of only a handful of engineers ever to hold that designation. Every time Google understood what you meant rather than just what you typed, Singhal’s team was behind it.
He was definitely the most influential engineer of the twenty first century. He ran the most important piece of code in human history. (1)
These ten engineers built features and products that billions of people depend on. They wrote the code, designed the systems, and made the decisions that shape your digital life. And their names never come up in tech conversations.
