ABOUT ME
Startup-friendly backend developer, poker player and coffee geek
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.
Product-wise I can help you choose the right tech stack for the problem, develop and drive your product in the right direction, lean style.

Heroku is my go-to PAAS when I need to deliver an MVP in no time without devops burden. It alows to scale the service in a couple clicks the only downside being the price tag.

I used to write a lot of Perl back in the day and I think it is still a great tool when it comes to tinkering with text and regular expressions. Perl programs are as robust as their C equivalents in text processing.
