About me
Founding Engineer and technical lead for early-stage companies. I own system architecture, implementation, and delivery—operating as your first technical hire to ship production systems and scale the engineering org when you're ready.
Based in San Francisco
Why work with me
- Hands-on technical leadership: I architect, build, and ship with you—not advise from the sidelines.
- 10+ years full-stack engineering; 5+ in AI/ML (LLMs, RAG, agentic systems, orchestration). Production stack: TypeScript, Python, React, Node.
- Track record scaling engineering orgs via vetted talent (e.g. Ukraine-based teams) when you need to ramp.
- Early-stage only: one full-time founding engineer role, equity-aligned.
Services
Founding Engineer and AI/LLM delivery for early-stage companies. Technical leadership that delivers production systems—not strategy alone.
Founding Engineer
Full-time technical lead or first engineer. I own system design, implementation, and delivery. Equity-focused; considering one founding role.
AI / LLM
RAG, agentic systems, and LLM pipelines—from prototype to production, with guardrails and evaluation in place. I deliver production systems, not POCs that stall.
