Work you can open, built by two or three people instead of fifteen.

Eighteen years of production software. Ten of them I ran my own company and grew it to a team of about fifteen engineers. Today I deliver the same scope with two or three people and an AI-assisted workflow. I've run it both ways, and measured it.

Available for contract and fixed-scope work — remote, across EU and US hours.

Work

Models

Each one marked by what I actually did. The colour is how close my hands were to the training.

  • Part and wheel segmentationYOLO segmentation of 23 part classes, in production.

  • Image taggingPart, side and travel direction per image.

  • Camera-position-aware modelsA model per camera layout, plus rules for what each sees.

  • Capture guidanceRight level, distance and angle, images collected automatically.

What I sell

  • Fixed-scope build

    An agreed scope at an agreed price, working and deployed in days rather than months.

  • AI integration

    Models and automation inside a product people actually use, not a demo that impresses once.

  • Integration work

    Making the systems a business already runs on talk to each other, and stay in sync.

  • Fractional tech lead

    Senior engineering judgment on the days you need it, without a permanent hire.

What I build most often

  • Offline-first field apps

    A durable local queue, ordered replay, and conflicts resolved against server state on reconnect — so nobody has to think about being offline.

  • AI document pipelines

    Isolated stages, each retrying on its own, with an audit record per step. One bad input never stalls the batch.

  • Operational reporting

    Pulls several internal APIs, narrows to the accounts that actually moved, and says plainly when nothing did.

  • Pricing & cost engines

    Prices a set of items against a reference table and serves it — with the snapshot built free of personal data.

  • System integrations

    Small bridges pulling from one API and pushing to another: dedup, retries, and a mock of the far end so failures are testable.

Record

  1. 2018 to now

    Architect and product owner, a multi-service platform

    I own the architecture and the product: 11 backend services and 6 front-end apps, multi-tenant across 27 locations in 9 countries. Offline-first field apps, AI document pipelines, computer vision, SSO and permissions, and the integrations that keep separate systems in sync. I write a large part of it myself.

  2. 2020 to now

    Independent

    Fixed-scope builds, AI integration and fractional tech-lead work, taken on directly.

  3. 2008 to 2018

    Founder and engineering lead, my own software company

    Grew it from the first paying client to about fifteen engineers and more than a hundred delivered projects, owning architecture, hiring, delivery and the client relationships that paid for all three.

How I work

I talk to the people who will use the thing and agree the workflow before anyone writes code. Then a working prototype goes into real use as fast as possible, and everything after that is tuning against reality instead of guessing.

  • Remote and async-first, across EU and US hours, in English.
  • Scope agreed before anyone writes code, so you know what you are getting and when.
  • Direct and low-overhead: you talk to the person doing the work.
