What I do

Two lines, a single person

So your brand actually shows up, or your company stops fighting its own tools.

Why work with me

What you get when there's no agency in the middle

You talk to me from the first message to the last deliverable. No middlemen, no junior team learning on your dime.

  • Honest

    If something doesn't pay off, I'll tell you before I charge for it.

  • Direct

    No pitches, no sales script. We talk about the problem.

  • Senior

    Twelve-plus years with hands on code and infrastructure.

  • Close

    Zero middlemen. You talk to the person who ships, from the first message.

  • Resolute

    Closing proposal with concrete scope and timeline in five days.

How I work

Five steps, no surprises

Before I charge anything, you know what we'll do, how long it takes and how much it costs.

  1. Talk

    A 30-minute call to understand what's blocking you.

  2. Diagnosis

    I look at the real picture: data, processes, team, budget.

  3. Proposal

    Five days later: closed scope and fixed price.

  4. Build

    Weekly drops in a direct channel. No surprises.

  5. Hand-off

    Documentation, training, support if you need it.

Who's behind this

Senior engineer. No agency, no team learning on you.

Twelve years designing data platforms and infrastructure — from three-person startups to corporates with thousands. I started in banking back when banks were discovering they had data.

Today I help small firms avoid the same mistakes. I work alone, with technical honesty: if something doesn't pay off, I'll tell you before I charge for it.

Public demos

The code is live, navigable and open

Four experiments in production. Each one shows how I build: educational UX, data visualisation, internal tooling and a browser-side runtime.

30 minutes to understand what's blocking you

I reply within 24 business hours. If we fit, I send you next step and a fixed price. If not, I'll still point you somewhere useful — no sales script.
