Everything About Me

I'm a full-stack engineer with 3+ years of experience in building, shipping, and maintaining modern software products end-to-end. I'm actively transitioning into GenAI / LLM application engineering, where I build practical prototypes and features using modern LLM tooling—prioritizing clear architecture, predictable behavior, and polished UX over "demo-only" results.

What I Optimize For

  • Fast iteration without chaos (simple, repeatable workflows; good defaults)
  • Clean, maintainable architecture (modular code, clear boundaries)
  • Performance & scalability (responsive UX, efficient APIs, sensible data flow)
  • Pragmatic AI decisions (right model/tool for the job, based on constraints)
