New here? Start with the €750 roadmap

Four ways to work together

Full details →

01

Scoping & Roadmap Session

one week turnaround · €750

Know exactly what to build before spending real money. A working session plus a written roadmap: what to build first, what to skip, what it will cost, and the fastest safe way to ship it.

02

AI Integration Sprint

2-3 weeks · from €7,500

Ship one production-grade AI capability into your product: a RAG assistant over your data, an agentic workflow, document intelligence, or a customer-facing bot. With evaluation, guardrails, and monitoring. Not a demo that falls over in front of users.

03

MVP & Product Build

4-8 weeks · from €18,000

From validated idea to a deployed, monitored product: web platforms, SaaS, and mobile apps. Boring, proven architecture where possible; sophisticated only where it earns its keep. You get weekly demos of working software, never slide decks.

04

Fractional Senior Engineering

ongoing · monthly · from €4,500/mo

Senior engineering capacity without a senior hire: architecture reviews, hard bugs, AI feature work, and mentoring for your existing team. Direct communication with the senior engineer doing the work, no agency layer.

How an engagement actually runs

The process is designed around one idea: you should never wonder what's happening with your project or your money.

01

Intro call

30 minutes, free. We establish what you're building, what's blocking you, and whether we're the right fit. If we're not, we'll say so and point you somewhere better.

02

Written proposal

Within 48 hours you get a fixed scope, a price, and a timeline in writing, including what's explicitly out of scope. No surprises invoiced later.

03

Weekly working software

Every week ends with a demo of deployed software and a short written update. You always know where the project stands.

04

Handover & ownership

You own the code, the infrastructure, and the accounts from day one. Handover includes documentation and a walkthrough. No lock-in, ever.

What you're actually buying

We're not the cheapest option, and we'll never pretend to be. What you get for the price is judgment, evidence, and software that holds up after launch.

You talk to the engineer

No account managers, no juniors doing the work behind a senior's face. Whoever is on the call is writing the code.

Boring where it should be

Proven tools for the foundation, sophistication only where it creates advantage. Your product shouldn't be our experiment.

AI with evidence

Every AI feature ships with an evaluation harness. If quality can't be measured, it isn't done.

Fixed scope, in writing

Proposals state what's included, what isn't, and what it costs. Change requests are welcome. They get priced, not smuggled in.

TypeScript / React / Next.js / Node.js / Python / PostgreSQL / Anthropic / OpenAI APIs / RAG & Evals / AWS / Vercel / Docker / CI/CD

Who you're hiring

I spent more than a decade engineering inside large enterprise environments, the kind where downtime has a price tag and “works on my machine” isn't an answer. I started MoonShift Lab to bring that standard to founders and product teams who need things built right the first time.

I run the studio deliberately small: few projects, full attention, no account managers, no juniors behind a senior's face. When you book a call, I'm the one who picks up, and I'm the one who writes the code.

Notes on building

“Every failed software project we have ever been asked to rescue had healthy status reports.”

Most early products don't need the database yet

The most expensive line in an early-stage codebase is the one that adds infrastructure before it adds users. A field guide to deferring complexity without painting yourself into a corner.

The handover test

A simple standard for judging any external development team, including us: if they vanished tomorrow, how bad would it be? The answer is decided months earlier than most clients think.

Have something that
needs to exist?

Tell us what you're building. You'll get a straight answer about whether we can help, what it costs, and how long it takes. No obligation, and no sales script.
