Ideas to productionon time, in budget

Full-stack product engineering with an integration at the heart. I design the architecture, build the frontend and tie it into the backend. Ten years across banking, logistics, energy and ERP keep me honest.

What I do

I solve problems and I promise
no spaghetti, I love what I do, and you will too.

01

Enterprise Integration

Long engagements · 3–12 months

API-led and event-driven integrations across banking, logistics, energy, retail, and ERP — the connective tissue that keeps the rest of the business running. Synchronous APIs where they fit, the right message bus where they don’t, and MCP servers for the AI tools that increasingly need to reach into the same systems. Honest naming, deliberate scope, and a runbook your team can still read in six months.

02

AI Training & Teaching

Workshops & embedded · Weeks to a quarter

Helping teams use AI tools well. Workshops, 1:1 coaching, and embedded engagements that get your engineers past "I tried Copilot once" to genuinely faster shipping. Tailored to your stack and codebase — it is about building habits.

03

Product Engineering

Short sprints · 4–12 weeks

Solo, end-to-end builds — idea to deployed product. Internal tools, prototypes, AI-powered features that need to ship in weeks. I cover backend, frontend, infra, and the integration while getting business on the same page because that’s usually where these projects stall.
