Profile

I'm a natural born software engineer. I mostly enjoy spending my work life in a terminal, solving the puzzles of large scale systems. During my work experience I was often exposed to non-trivial obstacles of creating, delivering and maintaining bleeding edge software in a harsh conditions where potential issues required instantaneous actions. In my career I've used multiple programming languages, frameworks and tools to get desired results done in a most efficient time/cost manner. As of 2022, my favourite technology stack is a Golang microservice running either on top of Kubernetes or as a serverless function. Software craftsmanship is one of my passions - if you wish to hear more from me, don't hesitate and shoot me an email. I'd be more than happy to speak up my mind 😊
