Startup-friendly backend developer, poker player and coffee geek
I've got more than 10 years of experience building backend systems across varying problem domains and tech stacks, in big companies and startups. I've set up machine learning pipelines, managed big data with Hadoop and orchestrated swarms of microservices.
