Production MCP Servers

Your team asks Claude a question, the AI pulls answers from your business data. Multiple MCP servers with domain-specific tools (search, analytics, reporting), secured with OAuth.

Integrations That Survive Outages

A public live demo of one order running through five outside systems. Cut a line yourself and watch the queue retry, deduplicate, and park whatever will not go through in a backlog a person can see.

AI agents, automated pipelines, and production TypeScript, built to run without you.

From intelligent automation that decides autonomously, to MCP servers that let your team query business data through Claude or ChatGPT. I turn your applications into tools that work for you. 15 years of shipping software, now supercharged with AI.

Straight talk
Prices are honest starting points, not anchors. The discovery call gives you a fixed number before you commit to anything. If your problem doesn't need AI, I'll say so and point you at the cheaper solution. I'd rather lose the project than sell you something that doesn't pay for itself.

Not sure which package fits?

Describe the problem in two sentences. I'll tell you what it takes, what it costs, and whether it's worth doing at all.

A senior engineer who ships, and who is easy to work with.

I'm Daniel, a full-stack engineer based in Germany with 15 years of shipping production software, now focused entirely on AI automation. For years I've been the sole developer behind 12 enterprise apps at ADAC, Europe's largest motoring association, so I'm used to owning a system end to end: architecture, build, deploy, and the unglamorous maintenance that keeps it alive.

Working with me is deliberately low-friction. You talk to the engineer building it. No account managers, no hand-offs. I work from Germany with clients worldwide, in English or German, and overlap with both European and US hours.

Direct line
You talk to the person writing the code. No middle layer, no telephone game.
You always know where things stand
Daily progress updates and weekly Loom demos. No black boxes.
Honest scoping
If something's a bad idea, I'll tell you before you pay for it.
Yours to keep
Documented, deployed, handed over clean. No lock-in.

From idea to production, in four clear phases.

01

Discovery

A focused call to define scope, success criteria and the technical approach. You get a concrete plan, not a vague estimate.

free
02

Prototype

A working prototype on real code and real data. You evaluate it before committing to the full scope.

before you commit
03

Build & Iterate

Regular progress updates and demos via Loom. Clean modular code, deployed continuously. No surprises, no black boxes.

04

Handoff

Documented and deployed, with post-launch support included. The next developer will thank you.
