What I build
Systems that do the hard work.
Interfaces that stay out of the way.
I build RAG pipelines, tool-using agents, and MCP servers that actually get things done.
OpenAIAnthropicLangGraphpgvectorn8nI build products end to end, from the frontend to the backend and the infrastructure running underneath it. TypeScript, Node, FastAPI, whatever fits the job.
Next.jsFastAPIPostgreSQLAWSI build interfaces that feel good to use without sacrificing performance. Motion has a purpose, and I make sure it still feels smooth on the hardware people actually use.
GSAPFramer motionCore Web VitalsA11yApperioI build automated trading systems end to end: signal logic, risk management and live execution, plus the tooling that parses raw backtest reports into equity curves and trade journals. The test is whether a signal still holds on data it hasn’t seen, not whether it looks good on a chart.
