About Me

Hi, I'm Krystian Mikrut -- a .NET developer and tech lead with 12+ years in software engineering, including 6 years in leadership roles.

Before I wrote my first line of code, I spent 10 years as a plumber. Turns out, debugging leaky pipes is surprisingly good training for debugging leaky abstractions. That career taught me problem-solving under pressure, attention to detail, and the value of doing things right the first time.

My biggest project: an IoT Alarm Receiving Centre on Azure serving 300,000+ users and processing 10 million+ events daily with zero downtime. Built with Cosmos DB, Service Bus, Azure Functions, and API Management -- all managed via Pulumi IaC, zone redundant.

Currently, I'm focused on breaking legacy systems and building AI agents -- using n8n workflows, code execution agents, and exploring the intersection of .NET and AI. Goal: Microsoft MVP.
