About us

NOSIRIUS is a Kyiv‑based engineering studio that grew from a small circle of .NET enthusiasts into a full‑scale data‑access team. We started by integrating legacy information systems and gradually built our own approach to Entity Framework—from the very first context initialization to automated query profiling in production. The core idea behind every NOSIRIUS project is transparency. We share only the techniques we trust in our client work and document each step so it can be reproduced without extra tooling.

The course is crafted by an interdisciplinary crew of developers, technical writers, and knowledge‑management specialists. Each module passes multiple internal reviews—architectural, editorial, and practical—so the guides stay concise and the code samples match current .NET and SQL‑server versions. Our authors explain not only “how” but also “why”, presenting alternative approaches and the trade‑offs behind every decision.

We believe in steady progress rather than leaps and memorized “magic” patterns. That is why the course is divided into short logical blocks; each ends with a task in which learners replicate the techniques inside a real repository. The outcome is stored as a separate Git branch, making it easy to track the solution’s evolution from simple models to production‑grade settings.

The NOSIRIUS support service answers all technical and logistical queries within one business day. We carefully collect frequent questions and add them to living documentation so future readers find answers instantly. If a message calls for a deep code review, we respect repository privacy and provide structured feedback with references to relevant course sections.

Today NOSIRIUS unites professionals from Ukraine, Poland, and Portugal, yet every material is published simultaneously in Ukrainian and English. Our aim is to let specialists share knowledge freely, regardless of country or background: clear texts, runnable examples, and a touch of perseverance are all that’s needed.
