AI Product Engineering · Porto → EU & UK

Build it.
Ship it.
Run it.

Web app, mobile app, the AI features inside them and the infrastructure underneath — designed, built and live in production in weeks. One senior engineer, no agency layers, no handoff to juniors.

The gap

Getting a demo working is easy now. Getting it to production isn't.

  • Your prototype impresses in a demo and falls over with ten real users
  • The AI feature works on your laptop — nobody knows what it costs or when it's wrong
  • An agency quoted six months and four people for something one person should build
  • You're paying for a codebase nobody can deploy, test or hand over
  • Your investors asked when it ships, and you don't have a real answer

“Anyone can generate a prototype in a weekend now. The scarce part is the judgement about what survives real users — and being there when it doesn't.”

— How we decide what ships

Weeks, not quarters

A real product in front of real users in 4–6 weeks, not a roadmap.

You keep the keys

Your repos, your cloud accounts, documented. No lock-in, ever.

Services

Three ways to start

Fixed scope, fixed price, named deliverable. You always know what you're getting and when.

Prototype Rescue

You already built something — with a no-code tool, an AI coding assistant, or a freelancer who's gone. We make it real.

Fixed scope · 2–3 weeks


  • Honest assessment of what to keep and what to rewrite
  • Proper auth, data model and secrets — not hardcoded
  • Repeatable deploys instead of manual uploads
  • Monitoring, so you hear about breakage before your users do
  • Best for: a demo that needs to become a product
Get it assessed

AI Automation

The repetitive work inside your company, handed to agents and workflows that plug into the tools you already use.

Fixed scope · from 2 weeks


  • Workflow automation with n8n and custom services
  • MCP servers, so assistants can safely use your own systems
  • Retrieval over your documents and data (pgvector, embeddings)
  • Self-hosted models where data can't leave (Ollama)
  • Best for: teams drowning in manual process
Automate something

Not ready for a full sprint? The Product Blueprint is one week at €2,500 — architecture, a deployed skeleton and a fixed quote, credited back if you go ahead. Need it ongoing instead? Fractional CTO is a monthly retainer.

What we bring

One engineer who covers the whole stack

15+ years across startups and enterprise — McKinsey, Natixis, Ericsson — plus five products taken from zero to production in the last three years.

Product engineering

React Native and Expo for mobile, Next.js for web, Node and GraphQL behind them. Shipped to the App Store and Play Store, not just to a staging URL.

AI that works in production

Semantic search and matching with pgvector, LangChain pipelines, MCP servers, agent workflows — with evaluation and cost control attached.

Cloud & platform

AWS, GCP, Kubernetes, Terraform, CI/CD and observability. The part most product shops skip, built by someone who did it at banking scale.

Fractional CTO

Architecture decisions, delivery planning and technical hiring — the technical co-founder you haven't hired yet.

How we work

No discovery theatre. Four steps.

You get working software in the first fortnight, not a specification document in the first month.

Start with step one

Free product teardown

Two hours on what you're building, what exists already and what's actually blocking launch. You leave with a written plan and a number — free, no commitment.

Fixed scope, fixed price

We agree exactly what ships, in what order and for what cost. No open-ended hours, no change-request games.

Built in the open

We work in your repos and your cloud accounts, shipping every week. You see it running, not screenshots of it.

Hand over or stay on

Docs, runbooks and a walkthrough. Keep us on retainer, or take it in-house — and we'll help you hire the person who does.

For startups & incubators

Built for teams before their first engineering hire

Early-stage terms for startups, and dedicated programmes for the incubators and accelerators that back them.

Free Product Teardown

Two hours on your product, your stack and your launch blockers — free, no strings attached.


  • Review of what you've built so far

What makes us different

We build it, then we find the person who takes it over

The usual objection to outside engineering is “what happens when you leave?”. We answer it by running the hire ourselves — engineers screening engineers, on the codebase we wrote.

We build

Your product ships and runs in production, documented as we go.

We hire

Our recruitment side sources and technically screens your first engineer.

We hand over

We onboard them onto the system we built, then step back.

FAQ

Straight answers

How fast can you actually ship?
A working product in front of real users in 4–6 weeks. Not a clickable demo — a real app with real auth, real data, real deployments and monitoring. Five products have gone zero-to-production this way in the last three years.
Do you use AI to write the code?
Yes, heavily — that's part of why it's fast, and we'd rather say so than pretend otherwise. The difference is what happens next: 15+ years of production engineering decides what actually ships, and everything gets tested, deployed and monitored like real software. The speed comes from the tooling. The judgement doesn't.
Can you take over something we already built?
That's one of the most common requests — whether it came from a no-code tool, an AI coding assistant, or a freelancer who's moved on. We'll tell you honestly what's worth keeping, rebuild what isn't, and get it onto infrastructure that survives real traffic.
Why one engineer instead of an agency?
Because much of an agency's cost is coordination between people who each own a slice. One senior engineer who can do product, AI and infrastructure removes the handoffs entirely. For larger builds we bring in a small trusted network — but you always work directly with the person writing the code.
What technologies do you work with?
React Native and Expo, Next.js, Node, Python, GraphQL and Hasura, PostgreSQL with pgvector, LangChain, Ollama, MCP servers and n8n — on AWS, GCP or DigitalOcean, with Terraform, Kubernetes and GitHub Actions underneath.
What happens when we hire our own team?
That's the goal, and a good outcome. We document everything, then our recruitment side finds and technically screens the engineer who takes over, and we onboard them onto the system directly.
