.NET Backend & Distributed Systems Engineer

Dawid Mika

Building reliable, scalable software with .NET & C#.

Available for freelance work & collaborations

Backend Engineer specializing in distributed systems and HA infrastructure. Designed and built a three-tier platform managing thousands of live game servers running 24/7 in production — from the central orchestration layer down to individual server agents injecting directly into game processes. Experienced in the .NET ecosystem, microservices architecture, API design, and DevOps practices.

+ Years of experience

+ Projects delivered

+ Technologies used

Backend Development

APIs and services built with ASP.NET Core and EF Core, focused on clean boundaries, testability, and performance under real load.

Blazor & Frontend

Interactive UIs with Blazor Server and WebAssembly — component-driven, accessible, and easy to reason about without a separate JS framework.

Cloud & DevOps

Containerized deployments, CI/CD pipelines, and cloud infrastructure that make shipping a non-event instead of a fire drill.

Backend & API Development

ASP.NET Core APIs, microservices, and distributed systems designed to hold up under real production load.

Legacy Modernization

Untangling technical debt and moving monoliths toward modular, maintainable architectures — incrementally, without stopping the business.

Contract & Team Augmentation

Embedded on a B2B contract — sprints, code review, architecture decisions, and full ownership of a module or service.

I run my own registered business (Net Glow Studios) — happy to invoice B2B, no employment contract or umbrella company needed.
