Staff Python Engineer @ Rossum / PyData Prague Co-Organizer
About
I help machine learning/research teams to pay off the technical debt and to transform validated ML prototypes into production.
I have hands-on experience with Python backend development, cloud-native microservices, message brokers, relational and various NoSQL databases, observability, continuous integration, static analysis, automated testing and developer experience. I have a broad exposure to problems solved by SRE and MLOps and enjoy expanding that knowledge.
I can work independently, cooperate in a team or lead a small team as needed -- interesting work matters more than a fancy job title. I spent 11 years in customer-facing IT roles until 2016 and since then I do my passion, Python for machine learning on Linux in the cloud.
I am a curious and quick learner, strong analytical thinker, knowledge base builder, frequent user of common sense and simplification freak. I prefer proactive design over firefighting and sharing over knowledge silos. I believe in freedom and responsibility at work and I try to give back to the community.
I live in Prague (and don't plan to relocate), work 4 days a week, mostly remote and as a regular employee (no freelancing/B2B contracts, please).
