Hi there 👋

About

Backend-focused .NET developer building services in C#/.NET with a strong interest in cloud (AWS), containerized deployments, and observability.

I’m building a small AI-native platform operations stack: Kubernetes-MCP-Guard an MCP-based Kubernetes control layer with OAuth, RBAC, audit, guardrails, and approval-gated changes and a weather microservices.

Tech stack

  • Core: C#, .NET, AWS
  • Architecture: Microservices, CQRS, SOLID
  • Communication: REST, gRPC, GraphQL, SignalR, messaging (RabbitMQ / SQS)
  • Data: SQL / T-SQL, PostgreSQL, MongoDB, Redis
  • DevOps/Tools: Kubernetes, Docker, Git, CI/CD, Grafana, Postman/Insomnia, Rider / Visual Studio / VS Code
  • Libraries: EF Core, Dapper, MediatR, Hangfire, Serilog (Seq)
  • Testing: xUnit/NUnit, Moq, AutoFixture

What I've worked on (high level)

  • Designing and maintaining backend services/APIs in .NET (incl. AWS integrations)
  • Building microservice-based systems with Docker and async workflows
  • Integrations with external services/tooling (e.g. Stripe)
  • Health checks, logging, and “keep it running” improvements (reliability/observability)
  • Writing tests, doing code reviews, and iterating on architecture

About 6 years of commercial experience

Certifications

Currently

  • Open to .NET Backend / Software Engineer roles (Poznań / hybrid / remote) — Mid / early Senior
  • Deepening AWS + cloud-native patterns and exploring AI tooling
