About 80% of my time at SpaceX and Tesla is dedicated to engineering and design, focusing on developing the next generation of products.

I'm a founder at OpenAI, focusing on robotics and the application of deep learning in this field.

I spent two years at Steve Jobs' side doing a biography, and then I followed Elon Musk for years to understand his journey and share that information.

At SpaceX, I work closely with the engineering team to improve the Falcon 9 and Dragon spacecraft, as well as develop the Mars colonial architecture.

At Tesla, I focus on the Model 3, spending time in the design studio on aesthetics and the overall look and feel, while also reviewing engineering aspects of the car and the factory.

I pursued my interests in math and sciences relentlessly, eventually studying mechanical engineering and working in aerospace before joining Tesla.

At Tesla, I became very interested in AI applications, particularly in autopilot technology, which led me to explore AI's potential in different domains.

I'm a software engineer at OpenAI working on Codex, which solves real problems I encounter daily in my work.
