About

I've worked mostly on the data side of backend engineering: pipelines that move, validate and clean up data, and the integrations that connect one platform to another.

Had experience on spearheading end-to-end development lifecycle of integrations, from evaluating each security platform and writing the design documents to shipping and supporting them in production.

Outside work I build full-stack side projects that leverage AI tools and capabilities.

Deployed to production on Railway (backend) and Vercel (frontend) with a custom domain.

myBulakenyos ARCHIVED

An early prototype built to learn in the early stages of my career. Deprecated and no longer maintained, but a useful early rep in the workflow-tooling muscle I still use today.

Let's Build Something

Open to backend-heavy projects, tooling work, or anything that needs someone comfortable owning a system end-to-end.
