Product engineer. I own the full stack — frontend, backend, database, infra, cloud, AI agents, and evals. Not just a coder; I take ideas from zero to shipped product. Currently building JobClaw and TestGen. I care less about technology debates and more about delivering results that people love using.

Experience

Where I've worked and what I built there.

Software Engineer, Agent

Architecting model-routing infrastructure and AI evaluation/RAG pipelines serving 100k+ daily requests across 8+ chat channels.

  • Architected and operated model-routing infrastructure with tier-based cost controls and provider abstraction (OpenAI/Gemini); served 100k+ daily AI requests across 8+ chat channels with sub-500ms response SLA
  • Engineered AI evaluation pipeline using GPT-4.1-Nano for event detection and GPT-5-Mini for trend analysis; reduced false positives 27% through validation loops and lifecycle testing
  • Implemented production-grade RAG/agentic workflows with memory modules and hallucination mitigation; achieved 30% faster response accuracy and 40% hallucination reduction
  • Solved Redis cache stampede and Elasticsearch scoring issues; dropped API latency from 800ms to 495ms via proper TTL management and refresh strategy
  • Built public marketing copilot with 6 autonomous agents across 8 social channels via MCP/CLI; automated 2k+ posts/week while maintaining human approval workflow
