Sharing knowledge

Working as a developer means being a part of a global community. We all use open-source code and learn from free tutorials.

I try to give back to this community as much as possible, by sharing my knowledge with others. The one I’m most proud of? The 3-part long introduction to Unicode:

I’ve also written about faster file uploads in JS , managing versions with git tags , using GitLab CI and more. All my blog posts are available for free on my Medium profile .

Conferences

Another great opportunity to share knowledge is during tech conferences. I’ve attended many meetups and conferences and always tried to give back as much as possible.

Becoming a speaker at an international conference is still on my bucket list. But I already tested my abilities when giving some lightning talks:

When not preparing for a lightning talk I try to help those who struggle to keep up with all the talks. I’ve been publishing notes for all the talks I attend:

• EuRuKo 2022 Unofficial Notes
• EuRuKo 2019 Unofficial Notes
• RubyKaigi 2018 Unofficial Notes

In Poland I also try to contribute to the local Warsaw Ruby User Group, where I already did a few talks:
