Old-school craft, modern AI tooling

Web & App developer

Every product starts as a rough idea and ends as something people quietly depend on. I work that whole distance, from shaping the concept to building it properly, then staying for the unglamorous part that keeps it worth returning to.

Full-cycle orchestration

Projects, web, and apps

  • 01Project management: roadmap rituals, risk boards, and concise reporting
  • 02Web development: modern component systems + honest API wiring
  • 03App development: React Native twins, native bridges, and testflight-ready drops

AI Integration

I put language models into products that already have users, along with the retrieval, tooling, and guardrails that keep them useful once real traffic arrives.

LLM integration

Claude, ChatGPT, and Gemini wired into existing apps, with streaming responses, tool calls, and sensible cost controls.

Retrieval & RAG

Document ingestion, embeddings, and vector search so answers are grounded in your own data instead of guesswork.

Self-hosted models

Private LLM setups for teams whose data cannot leave their own infrastructure, sized to the hardware you actually have.

Agents & automation

Multi-step agents that call your APIs and move real work forward, with evaluation loops to keep them honest.
