full-stack developer / AI engineer
I put language models into production and keep them honest: custom agent loops on the Anthropic SDK with forced tool use so the output is validated structure instead of free text, multi-step tool calling on the Vercel AI SDK, served from a typed Next.js frontend and a containerized FastAPI backend.

about me
who I am .
I'm self-taught. I studied on my own until a US consulting company building a team effectiveness SaaS platform took a chance on me with no dev experience, and I spent the next two years earning it: Stripe payments, a role-based permissions system, a production LLM integration, a full UI framework migration, and the tests to prove it all works. The full story is in the write-up.
I care about both sides of the stack. On the frontend, I sweat the details: hover states, spacing, the small interactions that make a site feel alive. On the backend, I care just as much that the data is validated, the permissions are right, and the API doesn't leak implementation details. If it ships, it should hold up.
Lately I've been going deeper on AI backends. I built an interview coaching agent on the Anthropic SDK with a custom agent loop and forced tool use, so the model returns validated structured output instead of free text, wrapped in a FastAPI service and containerized with Docker.
