About Me

Know Me More

I'm Marcin Czernecki, a Software Engineer

Hey there! I'm Marcin Czernecki and I am a software developer based in Barcelona, Spain. I enjoy building apps for any platform: desktop, web and mobile but my real calling is web/cloud development.

As a developer you have to be able to code in a number of languages to be successful. I have learned a ton from others by reading and watching hundreds (maybe even thousands) of tutorials and keeping up with blogs from top developers and designers.
