ABOUT ME

Who I am and how I work

Production-focused .NET Software Engineer with 5 years of experience in distributed systems, RESTful API design, and high-performance C# software development. Combined background of delivering enterprise projects for commercial clients and building complex software products from scratch. Deep expertise in the modern .NET stack, microservices, Docker, CI/CD, and system-level performance optimization.

+ 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.

HOW I CAN HELP

Freelance & contract work

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.
