Services

Three things, done at a senior level.

We build custom software and AI systems, on infrastructure that holds up. No long menu of disciplines — these three, done well, by the people who'll actually do the work.

Product DevelopmentAI SolutionsCloud & DevOps
01

Product Development

We design and build software that fits your business, not a template. Greenfield products, platform rebuilds, and the unglamorous integration work that makes the rest possible.

Case study: From single-tenant to 3× faster multi-tenant SaaS →

Most of what we build is a web or mobile product with real users and real money behind it. We start from the outcome you need and work backwards to an architecture that gets there — then ship in small, reviewable increments so you see progress every week, not at the end.

Senior engineers do the work end to end. That means production-grade code, sensible tests, and a system the next team can extend — not a prototype dressed up as a product. When the right move is a rebuild, we migrate incrementally behind feature flags so you keep shipping the whole way.

  • —Full-stack web applications
  • —Mobile and cross-platform apps
  • —Multi-tenant SaaS platforms
  • —APIs and integrations
  • —Legacy rebuilds and migrations
  • —Performance and scalability work
02

AI Solutions

We move AI from slide to production: integrations, document and workflow automation, and machine learning embedded where it changes a number you care about.

Case study: −63% manual data entry across a freight network →

The hard part of AI in production isn't the model — it's everything around it: getting the data in, validating the output, handling the cases the model gets wrong, and making the whole thing observable enough that you trust it. That's the work we do.

We build systems that know what they don't know. Confident answers go through automatically; uncertain ones route to a person with the context to decide. Every decision is logged and auditable, so AI earns its place in the workflow instead of becoming a liability you can't explain.

  • —LLM integration and orchestration
  • —Document and data extraction pipelines
  • —Workflow and back-office automation
  • —RAG and retrieval systems
  • —ML models in production
  • —Evaluation, monitoring, and guardrails
03

Cloud & DevOps

A supporting capability that runs underneath everything else we build: cloud infrastructure that's cost-efficient, observable, and resilient, with the pipelines to deploy it with confidence.

Case study: Zero-downtime cloud migration at 99.99% uptime →

Shipping software is half the job; operating it reliably is the other half. We set up infrastructure as code, CI/CD that makes deploys routine, and observability that tells you what's happening before your customers do — so the product team can move fast without breaking the things that matter.

We treat this as the foundation, not a separate sale. Most clients get it as part of a product or AI engagement; some come to us specifically to migrate, harden, or right-size what they already run. Either way, the goal is the same: an environment you can reason about and change without holding your breath.

  • —Cloud architecture (AWS, GCP, Azure)
  • —Kubernetes and containerization
  • —Infrastructure as code (Terraform)
  • —CI/CD pipelines
  • —Observability and alerting
  • —Cost and reliability reviews

Where we work

Four industries we know well.

SaaS

Multi-tenant platforms, billing, self-serve onboarding.

FinTech

Payments, reconciliation, compliance-aware systems.

E-Commerce

Headless storefronts, conversion, order management.

Logistics

Tracking, document automation, route and warehouse ops.

Common questions

How do we start working together?+

A short discovery phase. We scope the problem, agree on the outcome and a realistic timeline, and start building in small increments. You see working software within the first weeks, not at the end.

What does a typical project timeline look like?+

An MVP is usually 8–16 weeks; a focused rebuild or integration 6–10 weeks; a larger platform build 3–6 months. We work in two-week increments so scope and timeline stay visible the whole way.

Who owns the code and IP?+

You do. Full ownership of code, designs, and intellectual property transfers to you as standard. We hand over a system your team can run and extend.

Do you work with early-stage startups?+

Yes. We build MVPs for pre-seed and seed-stage founders, and in select cases take part of our compensation as equity. More on that on the About page.

Where is your team based?+

We're a senior European team, working across European, US, and Pacific time zones so there's meaningful daily overlap with clients on four continents.
