available for new projectsHi, I’m Ayush.
I build software people actually use.
I plan, design and build complete products: AI tools, the APIs behind them, the mobile apps on top, and the boring parts that keep them running, like security, limits and data migrations. Usually alone, start to finish.

// about
One engineer, the whole product.
I’m Ayush, a software engineer from India. I like owning a product from the first sketch to the day it goes live: planning it, designing the data, writing the backend and the apps, and fixing whatever breaks on launch day.
Most of my recent work has been for an education institute with tens of thousands of students: a new API, Android and iOS apps with live Zoom classes, an online exam platform, and moving years of data out of an old system. On the side I built Lets9go, an AI assistant for organisations, and PredictX, a prediction market.
I write things down, test before I say “done”, and tell you early when something is off.
- Logins and roles
- Usage limits
- Audit logs
- Error handling
- Automated tests
- Clean handover
