Jonathan Buchan · Product Engineer

Ideas to production without the bloat.

Full-stack product engineering with an integration spine. I design the architecture, build the frontend, wire the AI with guardrails, and ship the whole thing in weeks — not quarters. Ten years across banking, logistics, energy and ERP keep the corners honest.

What I do

Three offers, one underlying skill: making messy systems behave.

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.

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 — less hype, more measurable habit change.

Workshops · 1:1 coaching · Embedded onboarding

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, not quarters. I cover backend, frontend, infra, and the awkward integration glue, because that’s usually where these projects stall.
