Services and catalogue
How can I help you?
Write what you need into the box. An AI on my own machine works out which services fit, shows you the prices and writes a summary. If it fits, send it over for a quote. If not, adjust it first.
What whole projects have cost ↓
What I offer
Consulting
From requirements analysis through to process optimisation. Working out what is actually needed, what it is worth, and which half of the wish list earns nothing, before anybody writes code against a guess.
- What is this actually costing us, and which part is worth building?
- Do we even need new software for this?
- Can I get a number before I commission anything?
Application development
From prototype to production readiness. A prototype answers whether the idea works. The rest of the way is tests, monitoring, deployment and the faults that only appear once real people use it.
- The prototype runs. Can I put it into operation?
- Who repairs this when it fails at night?
- How long until I have something I can click through?
System architecture
From planning a system landscape to extending the systems you already run: interfaces that connect what you have. Manual retyping, and the errors and delays that come with it, are the largest single source of waste in small and mid-sized companies.
- Why is somebody here typing data from one system into another?
- Why do our stock figures disagree with each other?
- Can we extend what we have instead of buying something new?
Indicators, strategies, automation
The precise implementation of a trading plan, in code with no gaps in it. For retail and professional traders who want an idea built and validated by backtests, an already validated strategy automated by connecting it to a broker, or an explanation of why the strategy does something live that it never did on paper.
- Why does my strategy do something different live than in the backtest?
- How do I run my plan automatically without sitting up at night?
- Was the edge real, or did I fit it to the chart?
Platform & delivery
Containers, pipelines and the boring machinery that turns a release into a non-event.
- Why does every release cost us half a day?
- How do we take a bad deploy back?
- Who can ship when the one colleague who knows it is away?
AI & agents
LLM orchestration that does actual work: harnesses with memory, tool use, and quality gates a change has to clear before it counts as done.
- Can a model do this work, or will it just tell me what I want to hear?
- How do I check whether the output is right?
- What does running it cost per month?
Project examples
I estimate in complexity points rather than hours. €80 a point, the same rate for every job, so scope changes the number of points and never the rate.
A full indicator or strategy
The signal logic, the filters it needs, risk management and precise alerts — ready to use on the chart.
5–15 complexity points€400 – €1,200
A full trading system
Market structure across several timeframes, risk management and automated order execution. The range is wide because these systems differ more from each other than they resemble each other.
15–80 complexity points€1,200 – €6,400
Two systems kept in sync
One system writes, the other reads, and nobody retypes anything: the mapping, the scheduling, the cases where one side is down, and a log you can check when a figure looks wrong.
20–60 complexity points€1,600 – €4,800
A prototype you can click through
A rough version running on your real data inside two weeks, built to answer whether the idea holds. Deliberately incomplete, and cheap to change while the answer is still open.
10–25 complexity points€800 – €2,000
An existing system made fit for operation
Timeouts, retries, backups and the error paths nobody built the first time round, plus the logs and metrics that answer what it did at 14:32. For software that works and is not yet something you would leave running unattended.
15–40 complexity points€1,200 – €3,200
An assistant that does one job properly
A model wired to your own data and tools, with the checks a result has to pass before it counts as done, and an honest answer where a model turns out to be the wrong tool.
15–45 complexity points€1,200 – €3,600
A release that stops being an event
Build, tests and deploy from a push, with staging in front of live and a deploy that can be taken back in seconds.
8–20 complexity points€640 – €1,600
First needs analysis
A 90-minute conversation about your processes and bottlenecks, then a written result. It records what is needed, what can be left out and roughly what building it costs. For associations and businesses.
