Turns business needs into working products, from architectural scope to final delivery. From thousands of IoT sensors to fintech software.

Untangles any integration problem you throw at them. Thousands of real-time betting transactions for half a continent, a sales pipeline rebuilt for a national market leader, audio waves, analysed.

An investment marketplace, rebuilt and extended over five years, still in active development.
A legacy ad platform rebuilt as a modular, multi-brand SaaS with previews and GDPR roles.
Mobile games, a web system and the whole brand, built from the very beginning to support therapy for children.
Beyond the code, we can also lead your technology as a fractional CTO and build the team that runs it.
From first workshop to production and beyond. A business need goes in, working software comes out.
We set the technical direction, build and coach your team, and take responsibility for delivery, without a full-time hire.
We replace the old platform in stages, without pausing the business.
Payments, streaming, betting or IoT sensors and the integrations between them.
Assistants and agents that answer from your own documents and automate real workflows.
A senior review of your architecture, code and risks, with clear next steps.
Each of us has led teams of ten and budgets in the millions, so we know where projects go wrong before they start.
Each of us builds and owns delivery. You talk to the people doing the work, not a layer of managers.
Here since 2011, with clients who stay for many years.
We start with risks and trade-offs, before code.
Every change has a senior owner.
You talk to the same people from start to finish.

What AI-ready architecture actually means: modular design, event-driven infrastructure, and embedded AI, without rewriting your whole system.
