Custom software development
End‑to‑end delivery of web applications and services on .NET and modern SQL databases: from initial design and architecture to deployment and handover.
Who we are
Focused engineering for .NET & data‑driven systems.
We are a senior‑level engineering team based in Sisak, Croatia, focused on backend architecture, cloud‑ready APIs, and reliable data platforms for companies that need systems they can evolve and maintain for years.
What we do
Backend, data and web foundations that last.
We design and deliver maintainable systems – clean APIs, reliable databases, and simple frontends that stay understandable years from now.
Architecture & technical consulting
Reviewing existing systems, proposing pragmatic architectures, and helping you make technology decisions that balance performance, cost, and long‑term maintainability.
Team extension & outsourcing
Adding senior .NET and database engineers to your team on a flexible basis: covering delivery spikes, refactors, and long‑running maintenance work.
Maintenance & modernization
Stabilizing legacy codebases, improving performance, and gradually introducing cleaner patterns without big‑bang rewrites.
