The Untold Story of the Engineer Who Saved React.JS

This recent social media post by Rahul Pandey, co-founder of Taro Community and ex-Meta Staff Engineer, really caught my attention.

In it, Rahul shares a story about an engineer from Khan Academy who, back in 2013, got hired by Facebook because of her open-source contributions to React. Naturally, I was curious and dove into research—and what I found was mind-blowing.

This engineer didn’t just contribute to open source; she actually saved ReactJS. Let me tell you the story of Sophie Alpert.

Sophie Alpert’s journey in tech is the stuff of movies—an inspiring narrative filled with passion, innovation, and leadership.

When we think about engineers reaching the heights of people like Zuckerberg or Musk, the odds are staggering—maybe one in a billion.

But Sophie's path shows us what every engineer truly aspires to: not just a successful career at top companies, but real, lasting contributions to the community.

Early Life and Education

Sophie’s story begins in Colorado. Her parents, both familiar with coding, nurtured her love for technology from an early age. While other kids were reading comic books or novels, Sophie was reading computer manuals for fun. That’s how deep her passion ran.

By middle and high school, she was creating websites using Dreamweaver, coding personal projects, and even doing freelance work. Her skills were evolving fast.

She later went on to study computer science at Carnegie Mellon University, but the traditional classroom wasn’t cutting it for her. Sophie craved hands-on experience. So, after a summer internship at Khan Academy, where she developed interactive math tools, she made a bold decision—she dropped out of college to work there full-time.

Career Milestones

At Khan Academy, Sophie’s contributions were pivotal. She helped develop educational tools that transformed user experiences, reinforcing her belief that practical applications beat out theoretical knowledge any day.

But it was her transition to the React core team at Facebook that marked a defining moment in her career. Initially, Sophie was just an enthusiastic open-source contributor, but she didn’t stop there. Over time, her work was so impactful that she was invited to lead the React team at Facebook.

Her focus? Making React more efficient and accessible for developers.

There’s a fantastic documentary by the YouTube channel HoneyPot that goes into this transition in detail, and it highlights just how instrumental Sophie’s contributions were.

Her work with React was so good, in fact, that Facebook couldn’t resist hiring her.

And as they say—the rest is history.

Today, React is the most popular web framework in the world, and its influence only continues to grow. Sure, open-source is a community effort, but if it weren’t for Sophie’s contributions and her fresh perspective back in 2013, React could’ve easily been just another failed tech experiment.

Insights and Philosophy

Throughout her career, Sophie has been vocal about the importance of side projects. To her, these unstructured projects are the ultimate test of creativity and problem-solving. They’re where real passion shines, and they often lead to breakthroughs that traditional work can’t always offer.
