What I do

Engineering with a product point of view.

I love solving technical problems that make people’s lives easier.

01 / Product engineering

Full stack systems people enjoy using

I work from interface decisions through APIs and data models. The result is a clear path from idea to reliable product.

React · Node.js · Python · SQL

02 / Applied AI

AI that earns its place in the workflow

I work across agents and computer vision plus local models and evaluation. Every choice stays anchored to evidence and a real user need.

PyTorch · LLMs · RAG · OpenCV

03 / Platforms

Infrastructure that stays out of the way

I design fast APIs and resilient edge pipelines. My developer tools make complex systems easier to operate.

Cloudflare · Docker · CI/CD · REST
