Fractional Chief Technology Officer

AI-native infrastructure,
production-ready, in weeks.

I've built multi-tenant AI platforms from scratch — RAG pipelines, agentic workflows, cost-controlled LLM orchestration, vector search, Stripe billing.

I know where the expensive mistakes are before you make them. Across fintech, AI SaaS, industrial supply, and cybersecurity — I've shipped it and it's running in production.

What I Do

AI Architecture Design

Define the right stack before you build it. RAG vs. fine-tuning, vector DB selection, multi-tenancy design, cost controls, observability. Avoid the expensive mistakes.

  • LLM stack selection (model, embedding, vector DB)
  • Multi-tenant AI architecture with data isolation
  • Cost modeling and usage-based billing design
  • Observability and evaluation framework

RAG & Agentic Systems

Production-grade retrieval-augmented generation and agentic workflow engineering. Not tutorial-level — real pipelines with namespacing, re-ranking, and function calling.

  • Namespace-isolated vector search per tenant
  • LangGraph / LangChain agentic workflow design
  • Function calling and tool use orchestration
  • Evaluation pipelines and hallucination monitoring

Full-Stack AI Product Build

End-to-end product delivery. Auth, database schema, AI layer, payments, deployment. I own the full stack so there are no handoff gaps between AI and product.

  • Next.js + FastAPI production architecture
  • Supabase / PostgreSQL with RLS
  • Stripe integration and credit-based billing
  • CI/CD on Fly.io, GCP, or AWS

Technical Hiring & Team Structure

Define the right roles for an AI-native engineering team, run the technical hiring process, and establish code review and engineering culture from day one.

  • AI/ML engineer role definition and sourcing
  • Technical interview design
  • Engineering process and code review culture
  • Tech lead identification and mentorship

Infrastructure & Cost Optimization

LLM API costs get expensive fast. I design systems with cost as a first-class constraint — caching, batching, prompt compression, model routing.

  • LLM cost modeling and token optimization
  • Caching strategies (semantic, exact-match)
  • Model routing (expensive ↔ cheap by query type)
  • Cloud resource right-sizing

Technical Due Diligence

Pre-investment or pre-acquisition technical assessment of AI-native companies. Architecture review, team capability, scalability risk, and honest cost projections.

  • AI architecture and codebase review
  • LLM infrastructure cost projections
  • Technical team and hiring gap assessment
  • Risk identification and mitigation plan

Best Fit

Seed to Series A
Building an AI-native product and need technical leadership without the full-time CTO salary.
B2B SaaS going AI-native
You have a working product and need to add AI layers without breaking what exists.
Investors doing tech DD
Pre-investment technical assessment of AI-native companies in your portfolio or pipeline.

Engagement Models

Architecture Sprint

Fixed scope
2–4 weeks

You need the right architecture defined before your team starts building. Deliverable: architecture doc, stack decisions, cost model.

Most Common

Build Partnership

2–3 days/week
3–6 months

You need an experienced technical lead who can make decisions and build. Best for early-stage AI-native products.

Ongoing Advisory

1 day/week
Ongoing

Your team is executing but you want experienced oversight on architecture, hiring decisions, and technical strategy.

Let's talk architecture.

30-minute call. Bring your hardest technical decision and we'll work through it. If there's a fit, we'll define the engagement from there.
