Who I am

I'm a self-motivated .NET backend developer with 328 hours of structured training and 4 completed projects — including a live application delivered for a paying client. I have hands-on experience with Clean Architecture, Microservices, JWT authentication, and Entity Framework Core, built through real projects rather than coursework. Based in Prague full-time, I'm looking for an internship where I can contribute from day one and grow alongside experienced engineers.

ASP.NET Core MVC · SQL Server · EF Core · Custom CMS Admin Panel

  • Designed, developed and deployed a full-stack web app for a paying client — actively used in production.
  • Built a CMS admin panel: client manages all content (blog, recipes, FAQ, pages) with no code changes.
  • Public features: health blog, diet recipes, BMI & weight calculators, testimonials, contact form.
  • Owned the full project lifecycle solo — requirements, development, deployment, handover.

  • 3 independent microservices — Auth (5001), FileMetadata (5002), FileStorage (5003) — behind Ocelot API Gateway.
  • Custom inter-service JWT middleware: no shared secret — tokens validated via HTTP call to Auth Service.
  • File sharing: Public (anonymous), Private (owner only), SharedWith (GUID whitelist).
  • Strict Clean Architecture across all services: API · Application · Core · Infrastructure.
