AI Product Engineer

I Design, Build & Ship Your AI Product End to End

Full-stack AI products on the modern stack: TypeScript, Next.js, Supabase, and the Vercel AI SDK. I lead the product, architecture, and critical engineering decisions from scope through launch, and I remain accountable for what ships.

Need an AI Product Shipped, Not a Strategy Deck?

I work with founders and product teams who need:

  • •A working AI/RAG product in users' hands in weeks, not a six-month roadmap
  • •A full-stack build on the modern stack (Next.js, Supabase, Vercel AI SDK), led coherently from front to back
  • •AI features that actually work in production: real retrieval, real grounding, no hallucinated demos
  • •A senior builder who ships the code, not a consultant who draws the diagram

How It Works

A predictable, low-friction path from first conversation to a shipped AI product — and a clean hand-off when the work is done.

1

Intro Call

30 min

We talk about what you're building and whether I'm the right fit. No pitch, a real product conversation.

2

Scoping

Week 1

I produce a written proposal with scope, outcomes, timeline, and stack. You know exactly what you're getting, and what "done" means, before we start.

3

Build & Ship

Weeks (sprint) or ongoing (retainer)

I lead the build across frontend, backend, AI pipeline, and deployment. You get senior judgment at every layer.

4

Handoff

Closeout

A deployed product, clean docs, and, if you're hiring a team, code your engineers can maintain.

Principal-Led. Accountable End to End.

I scope the product, establish the architecture, and stay directly involved in the work that determines whether it succeeds. You always know who owns the outcome.

When a build needs additional delivery capacity, I add it deliberately and transparently while retaining technical and product accountability. No hidden handoff and no loss of senior oversight.

Signature Specialty

AI/RAG Products That Actually Work.

I take AI products beyond the prototype: ingestion, retrieval, grounded outputs, security, observability, and a maintainable application layer built around the real user workflow.

The goal is useful software, not an AI demo: validate the hard assumptions early, then build the system that can earn a place in production.

Engineering Outcomes at Enterprise Scale

Measurable results from production systems I personally designed, built, and shipped across Fortune 500 and private-equity-backed environments.

Millions

Connected building devices served by the event-driven, serverless TypeScript platform I built at Carrier (Abound BMS) — IoT Core, Lambda, DynamoDB/Timestream.

99.99%

Uptime on the mission-critical, multi-region SaaS platform I architected and shipped for Siemens.

30%

Infrastructure cost reduction I delivered through FinOps and architecture discipline on an enterprise SaaS platform.

75%

Faster deployment cycles from the CI/CD pipelines I built and redesigned — GitHub Actions, blue-green releases, automated Vitest/Playwright gates.

1,000+

Servers migrated to AWS at Atlas Air on the multi-account landing zone and migration tooling I designed and built (AWS CDK, Terraform).

Insights for Builders and Technical Leaders

Practical thinking on product engineering, AI systems, and the decisions that turn a promising prototype into dependable software.
