About

Quality over complexity

We keep teams small and outcomes focused. We believe in strong fundamentals: clear architecture, automated tests, measurable SLOs, and documentation your team will actually use.

Principles

Security-first, least privilege, reproducible builds, and observable systems. If it isn't monitored, it doesn't exist.

.NET, Java, TypeScript/JavaScript, Docker, Kubernetes, PostgreSQL, Redis, MQTT, Keycloak, WireGuard, Terraform, and modern cloud tooling.
