ABOUT ME
Software engineer with a sense for code quality and maintainability.
Software engineer with a sense for code quality and maintainability.
Freelance software engineer with over a decade of experiences in healthcare life-critical development but also realtime networking applications.
I've worked in Python, Go, C++(11,14,17,20) with Docker and Kubernetes but also on low end devices like network routers.
I have a very strong sense for code quality and maintainability. The architecture and design of objects matters but you can't spent 90% of the project time (and money) designing a feature you won't use. It's about the balance and I believe I have it.

In Seznam (which is the Czech Google :) I was helping the team to bring up kubernetes and dockerize our applications. I wrote a master thesis about it together with some Go apps. Check my github profile, it's an open source.

Programmer in one of the full-text teams. Our team was in charge of search engine website and everything around it (logging, A/B testing). My job was to create support libraries across applications using technologies such as Python, Tornado, C++, Cython, Heka, ElasticSearch, Kibana, Kafka, Logstash. My specialities were Docker and Kubernetes as they were the topic of my master thesis. I've done a Kubernetes cluster bring-ups, stress-testing as well as Go programming.
