A few things I have built recently. Happy to walk through any of them.

Where I have worked so far, and what I was responsible for.

Engineer at AppXAppX(YC S21)NOV 2025 – NOW

Building applications from the ground up for educators and creators, and the backend behind them, which serves 400 million requests a day with high availability.

Open-source contributor at Twenty2025

Fixed UI bugs across the codebase, improving layout and responsiveness, and worked with the community to keep the design consistent across the platform.

Notes on what I am building and learning.

I am Rishi Kant, an engineer at AppX in Noida, India, currently exploring infrastructure, the Ethereum chain, lending protocols, cryptography, and how MPC works under the hood.

Away from the terminal I am usually listening to something loud or reading about distributed systems.

Say hello on any of these.
