Hi! I’m Karol, a remote Ruby on Rails and Ember.js consultant, currently working as CTO at BookingSync. I build ambitious and high performant web applications.
Thanks to several years of experience and learning new skills every day, I had a chance to work on variety of problems, from building applications from scratch to helping in growing advanced startups in post-MVP phase. The problems I particularly enjoy working and are areas of my expertise:
- building REST APIs
- implementing PCI DSS compliant microservices for credit card payments processing
- building beautiful and fast Single Page Applications
- higher level architecture
- refactoring legacy code and making it maintainable
I strongly believe in always giving back. That’s why I’ve been involed in many open source projects and have been sharing knowledge on multiple possibilities. I’m always happy to do paid open souce work, mentor developers and write guest blog posts.
At this moment I’m not available for Ruby on Rails or Ember.js consulting, being CTO and maintaing open source projects keeps me pretty busy ;).
