About
I build LLM-powered applications and agentic workflows. I have 8+ years of experience across backend systems, full-stack products and cloud infrastructure, taking systems from product requirements and architecture through implementation, testing, deployment and operational debugging.
Core stack: Python, TypeScript, Go, PostgreSQL, FastAPI, React, AWS, Docker.
Applied AI & agentic workflows
- Connect AI agents to APIs and tools through MCP, manage conversational context, and build workflows with structured outputs, checkpoints, retries and access controls.
- Use Codex and Claude Code to coordinate implementation, reviews and browser testing across repositories, with clear task boundaries and verification of deployed behavior.
- Work across product requirements, architecture and delivery, with attention to reliability, latency, cost and maintainability.
