turnover ;)
I am a software developer based in Warsaw, Poland (and Seoul, SK - depending on the time of the year). I spent 15+ years building software in various languages.
Recently I worked with early-stage startups using a variety of technologies to get work done. My experience includes async and reactive programming in Node.
In 2015-2016, I worked with an R&D team for developing Blockchain-based smart contract service (Java, bitcoinj, Python, Twisted, pycoin, JavaScript, React, Flux). I also collaborated on product development and hiring process. In 2014 I was involved in building prediction models (Clojure, Java, Storm, Trident, WEKA) with a big data startup.
My recent projects included a mix of frontend and backend work. Before that I spent several years on application and middleware development, integration and mediation solutions for major telecom companies.
I'm looking forward to hearing from you and learning more about the project.
Best regards,
Patryk
