Software development · Remote

One senior engineer. Front end to server.

React, Next.js, TypeScript, Node.js. I take a defined slice of your product and ship it — or slot into your team as capacity that does not need managing. Day rate or fixed price, agreed before anything starts.

  • Three systems in production
  • BSc Computer Science · 4 years professional
  • From €680/day · bookable from five days

The situation

Three ways to add capacity. Each costs more than it looks.

When a product team or an agency needs more hands, the standard options all carry a hidden invoice.

The hire

Months of sourcing and onboarding for work that needed shipping this quarter — and a permanent seat on the payroll for what was a temporary peak.

The agency

Capacity on paper, overhead in practice: account managers, briefing rounds, and the distance between the person who understood your product and the person who writes the code.

The stretched team

The roadmap absorbs it. Features slip, the refactoring waits, and the people you hired for product thinking spend their sprints working through the backlog.

The fourth option

A senior engineer who is productive in your codebase within days — follows your conventions, communicates in your rhythm, and can own a defined slice end to end: interface, logic, database, deployment. At a day rate or a fixed price you know before the start.

Services

Four ways to work together.

Development capacity

For agencies and product teams that need frontend capacity.

from €680

Website & landing page

For businesses that need to be found and to receive enquiries.

from €2,500

Custom web application

For work stuck in Excel, on paper or in WhatsApp.

from €9,000

Maintenance & operations

For anyone running something — built by me or by someone else.

from €90

Work

Three systems, running daily.

No concept studies, no templates. Three projects that shipped and get used.

Sales organisation

CRM, commission management and comparison portal

Full stack · three systems, one database

Three systems that used to be three spreadsheets — customer management, commission settlement and a public comparison portal, all sharing the same data.

  • React
  • Node.js
  • Express
  • PostgreSQL
  • Plesk

Hospitality

Point-of-sale system for a shisha bar

Front end & data model · tablet till

A till that fits how the venue works — rather than a venue reorganised to fit a till.

  • JavaScript
  • Database modelling
  • Touch UI

Cleaning company

Landing page and LinkedIn campaign

Front end & campaign · no framework

No builder, no framework weight: a page that loads — plus the campaign that brings people to it.

  • Vanilla JavaScript
  • HTML
  • CSS
  • AI image & video

Approach

Why this takes weeks, not quarters.

Because no brief passes through three departments, nothing needs translating — and because I work with modern tooling. What that means in practice is set out openly on its own page.

  1. The call

    30 minutes. You describe how things work today and what is wrong with it. I ask questions and tell you honestly whether I am the right fit. Free, and with nothing attached afterwards.

  2. Scope and fixed price

    One page: what gets built, what explicitly does not, by when, for how much. You sign a number, not an estimate. That page is also what we both measure the result against later.

  3. Building, in the open

    After roughly two weeks you see the first working version — not a picture of one, something you can click. Then a steady rhythm. You always know where things stand without having to attend meetings for it.

  4. Handover

    Go-live, a walkthrough, documentation, every credential. The code is yours. After that, either a maintenance agreement or silence — both are fine, and I have had both.

Common questions

What businesses ask first.

What does it cost?

Development capacity is €680 a day, bookable from five days, with a framework agreement for longer runs. Fixed-price work starts at €2,500 for a website and €9,000 for a custom web application — the exact number after a 30-minute call and a written scope, not before, because a number without a scope is worthless.

How long does it take?

A landing page, two to three weeks. A web application, four to ten weeks depending on scope. You see the first working version much earlier — usually after two weeks.

What happens if you are unavailable?

The fair question to ask one person. So: the code sits in a repository you have access to, documentation sits next to it, and nothing in the stack is exotic enough that only I can operate it. Any other developer can take over. That is not a contingency plan, it is the baseline.

Do I own the code?

Yes. Entirely, with all credentials, on final payment. No subscription you are locked into, no licence I can withdraw.

Do you handle maintenance?

Yes, from €90 a month: updates, security patches, backups, small changes. You do not have to take it — but software nobody maintains becomes a problem within two years.

Do you work remotely?

Yes. Around the Rhineland I am happy to come in person; everything else works remotely. Across three delivered projects, distance was never the issue.

Tell me what needs shipping.

30 minutes, no obligation, no slide deck. If I am not the right fit I will say so — and point you at someone who is, where I can. Reply within one working day.
