What I work on.

I work on a small number of projects at a time, so each one gets proper attention. You speak with me directly from the first email to the final handover.

How I work

Simple, predictable steps.

Every project follows the same five steps. No surprise invoices, no scope creep without a written change.

  1. 01

    Initial call

    We talk through what you need, the constraints, and the timeline. If I'm not the right fit, I'll say so.

  2. 02

    Written proposal

    You receive a written proposal with scope, milestones and a fixed price — nothing vague or open-ended.

  3. 03

    Development

    I build in regular, reviewable steps and send updates so you always know where things stand.

  4. 04

    Handover

    Production deployment, documentation and a walkthrough. You own the code, the accounts and the infrastructure.

  5. 05

    Aftercare

    Optional ongoing support for fixes, small improvements and changes as your product evolves.
