Open to work|
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.

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

How I Actually Use Claude and Codex CLI Agents Every Day
How I run two products solo using Claude Code and Codex CLI. The actual commands, MCP servers, and agent skills in my daily stack — no hype.
How I Automated My Daily Workflow Using OpenClaw
OpenClaw on a VPS: cron jobs that fix PR comments overnight, daily AI news summaries, product market fit research, and a job search agent for cold emails.
Mastering Human in the Loop: Building Powerful, Reasoning AI Agents
How to implement Human-in-the-Loop patterns with LangGraph: interrupt, checkpoint, and resume AI agent workflows for safe, accurate critical task execution.
