Continents, one delivery standard
Enterprise-grade by default
SSO, audit logging, role-based access, and data residency on every project — not as a premium add-on.
Built across BR · DE · PT
A team that natively speaks both European procurement and Brazilian operational reality.
Senior-only delivery
No bait-and-switch staffing. The senior who pitches is the senior who builds and the senior who supports.
What we do
Six practices, one delivery team.
We don't sell you a department. We embed senior people who can move between strategy, architecture, and code as the problem demands — and hand back something your engineers can own.
CTO as a Service
Fractional CTO leadership for funded startups and scale-ups.

A senior team, deliberately small.
We staff every engagement with the same people who pitch it. No layered agency, no rotating juniors — just the team you meet on day one.
Marcos Ramos
Founder & CEO
Two decades shipping enterprise systems across LATAM and DACH. Hands-on architect who still reviews production code on Friday afternoons.

Specialises in design systems and performant React. The person we trust with anything users will actually touch.
Alex Freitas
Back-End Engineer
Owns the systems users never see — APIs, data pipelines, and the integration glue that keeps everything talking. Quietly responsible for things not breaking at 3am.
Carlos Wimmer
Solutions Architect
Designs the systems behind the systems — cloud, data, and integration architectures that scale without rewrites.
Roberta Oliveira
