hi, i'm rajessen. i build across web, mobile, and ai / machine learning. based in ottawa.
day to day i live in react native, typescript, next.js, python, and postgres. on the ml side: langchain for agent orchestration, pytorch and tensorflow for model work, plus a lot of llm tooling. on weekends i make tiny browser games when i should be doing literally anything else.
a browser game i built. it has an end. most people never get there.
accept the challenge →leading a small dev studio shipping crms, seo tooling, ai agents, and mobile apps for 20+ smbs. own the technical roadmap, the hires, and the late nights. full stack across web, mobile, and cloud · whatever the client needs, we build. toronto, remote.
