Proven Success Across Industries

Fractional CTO and hands-on technical partner for AI-forward startups from idea stage through Series B-scale pressure. Embed with founders and product teams to turn ambiguous requirements into shippable systems: technical discovery, architecture, build-or-buy decisions, vendor and model selection, and the people/process work (hiring rubrics, code review culture, CI/CD) that keeps velocity honest after the first demo.

Portfolio spans $0–$25M ARR across home health care, real estate, e-commerce, and social — same playbook: map the constraint (compliance, data quality, latency, cost), design the smallest production slice, and ship with observability from day one
Deliver LangGraph (and adjacent) agent workflows, RAG over messy domain corpora, eval harnesses, and LLM-backed APIs that respect tenancy, PII, and each client's infra maturity — usually Python/FastAPI services paired with Next.js or existing app surfaces
Act as the single thread between execs, domain experts, and engineers: roadmap facilitation, sprint-level prioritization, interview loops, and crisp written specs so teams do not stall on alignment
