Summary

I'm a passionate software engineer, trainer, international conference speaker, and a blogger (http://4comprehension.com) who cares about quality, craftsmanship, clean code and getting things done.

I am a committer in a few big open source projects. Besides this, I am a ex-lead technical editor at Baeldung where I used to be responsible for the technical correctness of almost all articles published between 2016 and 2018.

Codementor is a great place where I can help people and not corporations.

Sessions are risk-free. Simply put, if I don't manage to help you, you get a refund immediately.

If you need an on-site training, I'm there for you as well (EU, North America)
