BACKEND / AI SYSTEMS ENGINEER

I build backend and AI systems that stay fast under load, and I care about the layer underneath the demo.

Webhooks acknowledged in under 10 ms, a vector database written from scratch in C++, an interview platform that validates every AI response.I'm obsessed with AI and love building things end to end, from the first idea to something people can actually use.

Projects

A GitHub App that reviews pull requests with an LLM and posts inline comments, built so webhook handling never blocks on AI work.

  • •Acknowledges PR webhook events in under 10 ms by queuing AI review work through BullMQ and Redis and returning immediately, which avoids GitHub's webhook timeout.
  • •Token-aware diff chunking with js-tiktoken and parse-diff: file-level diffs are bucketed by token count rather than line count, keeping prompts under Groq's context limit while preserving per-file context.
  • •Integrates Groq's GPT-OSS-120B through an OpenAI-compatible SDK, returns structured JSON reviews validated against a schema, and posts them as inline GitHub comments via Octokit.
  • •Automatic retries with exponential backoff (3 attempts at 5s, 10s and 20s) and Redis-backed rate limiting to control AI cost and absorb transient failures.

Experience

  • •Developed and launched 5+ multi-device responsive web portals using semantic HTML5 and memory-efficient JavaScript.
  • •Improved client UI load performance by ~30% through script modularization, fewer render-blocking assets and less layout recalculation.
  • •Found and fixed 10+ structural defects through isolated testing environments and peer code review, improving stability and runtime reliability.
