Complex enterprise integrations,
and products built from scratch.
We connect what you already run and build what's missing. You talk directly to the engineer.
Two lines of work, one technical standard.
Our specialty. Product and architecture end to end as well.
We connect what doesn't talk: ERPs, third-party APIs, payments, tax authorities.
Let's talk about this →Platforms, apps and internal systems built to fit. The projects in section 04 came from here.
Let's talk about this →Microservices, cloud-native on AWS, Google Cloud or Firebase. And monolith migrations.
Let's talk about this →Automation, data analysis and internal assistants where there's a concrete result.
Let's talk about this →
Engineers hiring engineers: we know what to look for and how to evaluate it.
We run the evaluation because we work in production with those profiles.
Let's talk about this →We speed up search and technical screening without lowering the evaluation bar.
Let's talk about this →We support the first months and clear the friction of onboarding.

Greenfield projects.
Architecture, backend, frontend and release, with the same team that maintains it afterwards.

Integration diagnostic.
Before a line of code: what systems you have, how they talk today and where it breaks.
- Scope
- Current integration map, data flows and single points of failure. Usually 4 to 8 systems.
- Duration
- Two weeks from kickoff, with one discovery session per critical system.
- Budget
- Fixed before we start. If you move on to implementation, it's deducted.
- Deliverable
- Technical document and presentation: map, prioritized risks and a staged plan.
- Testing
- Test cases per critical flow and acceptance criteria agreed in writing.
- Maintenance plan
- Monitoring, alerts, API contract versioning and a documented handover.
Four stages, one technical contact.
