Software Engineer | Backend Development

C#/.NET · Go

I'm a software engineer focused on backend development with C#/.NET and Go. I build APIs, data-processing services, developer tools, and infrastructure for self-hosted applications.

My background includes 6+ years in game development, building reusable systems and developer tools, optimizing runtime performance and memory use, and taking projects from prototype to production. I bring that experience to backend engineering, with an emphasis on clear architecture, predictable behavior, and maintainable code.

Open to backend engineering opportunities.

Featured Projects

Project What it does Engineering highlights
MangaRead.Backend ASP.NET Core REST API for a manga and web-novel reading platform, paired with a companion content crawler. Separate domain, application, and infrastructure layers; EF Core persistence and migrations; MySQL/SQLite; file-storage abstractions; structured logging; Docker and Linux service deployment tooling.
Shorty Go URL shortener with authenticated link management, cached redirects, and asynchronous click analytics. Redis caches URL lookups; a separate worker consumes RabbitMQ events and stores analytics in PostgreSQL. Includes JWT authentication, role-based authorization, rate limiting, Swagger documentation, and Docker Compose.
nixstead Modular NixOS homelab platform for configuring and operating self-hosted services. A shared service registry generates Nginx reverse-proxy, TLS, firewall, and health-check configuration. Includes Nix flakes, SOPS-encrypted secrets, Borg backups and restore workflows, and a Python setup wizard.
MangaRead.Crawler Configuration-driven .NET crawler for collecting manga and web-novel content, with backend-agnostic integration. JSON site definitions and XPath extraction support new static sources without changing crawler code. Configurable concurrency and Polly resilience policies control access to external sources; Linux service deployment is supported.
JuiceTwee C# node-based Unity editor and runtime for reusable animation and gameplay-effect sequences. ScriptableObject graphs and extensible effect nodes; separation of effect definitions from runtime targets, and editor tooling from runtime execution.
