Backend systems & APIs
Designing and building server-side applications and APIs, mostly in .NET — architecture, performance, and code that holds up in production.
.NET Engineer · Prague
Software and infrastructure, shipped reliably.
I work on backend systems and the infrastructure that ships them — from applications and APIs to CI/CD pipelines, containers, and Kubernetes. I also help modernize older systems, and I'm interested in putting AI to practical use.

What I do
Building, modernizing, and running systems — from design to deployment.
CI/CD, containers & Kubernetes
Setting up pipelines, containerizing services, and running them on Kubernetes clusters — the plumbing that gets code from commit to production.
Migrating to modern technologies
Moving applications off .NET Framework onto .NET 8 and beyond — incremental migration, cloud and container deployment, and cutting the dependencies that keep a system in the past.
AI & MCP server adoption
Bringing AI assistants into company workflows and building MCP (Model Context Protocol) servers that connect them safely to your systems and data — from pilot to production.

Migration audit
Fixed scope, fixed price, no commitment beyond it. I map your .NET Framework system and within two weeks you get:
- a dependency and risk overview
- an incremental migration plan to .NET 8+
- an effort estimate per phase
The ideal first step when a system is held together mostly by inertia.

About
I work on both sides of a deployment: the applications themselves and the infrastructure that gets them to users. Most often in .NET, but I treat tools as tools — a lot of my time goes into modernizing older systems and automating what used to be done by hand. Outside work, front-end motion and the practical side of AI.
