I build softwarethat I go onrunning myself.

Most contractors hand a project over and disappear. What I build keeps running under my responsibility afterwards — with deployment, TLS, backups and monitoring. One person accountable, no agency chain.

In the rack

Eight systems, seven of them running right now. Each module carries its project's own design and leads to the project page.

Services

Two ways in, each starting with a small fixed-price step. Running it afterwards comes with both.

Website & findability

Your website exists but customers don't find it. I look for the cause first — it usually sits in the technology, not the marketing — and fix it verifiably: load time, structure, local visibility, and a machine-readable description for Google and AI search.

Audit

The first three audits for €590 if I may show the result as a reference. Credited if you commission the work within four weeks.

How it runs

  1. Audit: name the causes before any work is commissioned, with scope and effort
  2. Repair the foundation: plugin conflicts, load time, duplicates, crawl hygiene
  3. Content and structure: distinct text per landing page, not swapped place names
  4. Make it machine-readable: Schema.org markup for Google and answer engines
  5. Hand over documentation complete enough to run the site without me

Afterwards: Maintenance & Operations from €99 / month

Custom software

A web application or app for your problem — and no abandonment afterwards. I build from concept through to production: payments, user accounts, protected content, integrations, and all the way into the Play Store when needed. Whether it becomes web or app is the first thing we settle.

How it runs

  1. Scoping: test the riskiest assumption first — and settle whether this really needs an app
  2. Record decisions in writing, with the alternatives and the reasoning
  3. Ship in stages, each one runnable and acceptable on its own
  4. Take it live: deployment, TLS, backups, monitoring — for apps including store review
  5. Keep running it or hand it over cleanly — your call, not mine

How I work, by example

In June I threw away my own codebase — after four months of work.

The Flutter app was far enough along to keep going. Analysis and market research said otherwise: standalone score trackers hit a ceiling of a few hundred downloads, and the actual usage sits in tournament organisation. So I wrote down the reasoning, decided against my own work, and started over. This is exactly the call I make for clients too — before money flows in the wrong direction, not after.

Write to me about what it is, when it needs to be done, and what you have already tried. You get an honest assessment back — including when that assessment is that you don't need me.
