Architecture-First Engineering Services
Senior engineers and architecture sprints for funded B2B SaaS startups and Mittelstand teams. Built to survive growth — not to be rewritten.
All engagements begin with a structured Architecture Sprint — where we define system logic, scalability risks, and execution roadmap before build.
Based in Berlin, we work with distributed teams across the EU to design and build production-ready web platforms, business software, and automation systems.
Core engineering domains
Five core service clusters
This is the commercial entry layer. Specialized audits, migrations, and narrower services remain available below as a second layer.
Architecture-led MVPs, product foundations, and scoped builds for teams that need a credible version one without creating rewrite debt.
Backend systems, APIs, event flows, and architecture decisions for products that need reliability clarified before scale exposes the cracks.
Web platforms, product interfaces, design systems, and frontend delivery for systems where UX and system logic need to work together cleanly.
Cloud infrastructure, deployment pipelines, observability, and resilience work for teams that need delivery and operations to scale together.
Data pipelines, AI workflows, CRM logic, and operational integrations that turn disconnected tools into usable systems.
Common scenarios we help with
We’re stuck with a fragile MVP
The product works, but every change breaks something.
When changes repeatedly cause side effects, architecture clarity is the next lever.
Our system doesn’t scale anymore
Traffic, data, or users grow — reliability doesn’t.
Scaling issues are usually system design issues, not only infrastructure issues.
We need to pass audits / compliance
Security, GDPR, data flows, and traceability must hold under review.
Compliance succeeds with clean architecture, not with late-stage workarounds.
Our analytics can’t be trusted
Decisions are made on dashboards nobody fully believes.
Growth decisions need reliable data, not only nice dashboards.
We’re rebuilding too often
Rewrites slow the roadmap and kill momentum.
Rewrites kill momentum; targeted architecture decisions save years.
