Started by a group of passionate developers as an internal event in 2013, Haxorz now become an Unconference focused on software craftsmanship, agile practices and innovative management.

Haxorz at Selleo is a part of an internal day we hold once a month. Started by a group of passionate developers in 2013, Haxorz now became an Unconference focused on software craftsmanship, agile practices and innovative management. And yes it is open for everyone.
The idea of Haxorz looks simple—sharing knowledge with other colleagues. Most talks are held in English, but you’re not forced to do that—if you don’t feel confident enough, presenting something in Polish is better than not presenting anything at all.

If you’re wondering how many advantages it has, let me list some of them.


Honing English.

As software developers we work with clients all around the globe and it means that the whole communication is held in this contemporary lingua franca.


Learning how to sell something.

Presenting is more than selling ‘a real product’. It means selling your ideas, concepts, solutions. Every time you try to encourage someone to do something, you’re selling your idea, or a piece of advice.


Do the above in a smaller scale.

If you have a dream or a goal to give a speech to millions of people, you’d better start small, or you rather fall. Seriously.


New formula

Today during our Feedback360 session I realized that most ideas, solutions and good practices we implemented here, at Selleo, are hardly known to the ‘outside’ world. We should spread them in order to give something back to the community we live and operate in.

This is way Haxorz became open, and we’ve been successful! Apart from guys from Selleo, we had 12 guests that could take part in our unconference. All in all there were more than 30 people—number that often exceeds more regular meet-ups.


Presentations and the curse of knowledge

Most people think that there’s no point in sharing something as ‘everyone knows it’ and ‘it’s obvious’. That’s the curse.If you’re wondering how many advantages it has, let me list some of them.

Arek Janik presentation about common CSS pitfalls made me realize that guys more into the backend do common mistakes that front-end ones don’t. Even though ‘it was obvious’ some people could benefit from his presentation and, down the road, make him spend less time to fix some broken layouts.


At Selleo people thrive in an environment where nurturing your skills and habits is a standard. We want to progress as individuals and as a team. We play to the same goal.

Darek Wylon presentation about giving a feedback to other people reminded me that nowhere in the past I had a chance to learn how to do it. Schools don’t teach it. In most companies ‘making a mistake’ is a kind of a deadline, labelling you as a man failure. Giving feedback is a skill one has to learn and today’s Haxorz was, I hope, a chance to show our guests how to do that in the right way.

There were also , more technical presentations. One about Rails by Tomasz Noworyta when he told us about challenges connected with internalization and metrics systems on the global project. We also had a chance to listen to Radosław Jędryszczak presenting how to do pair programming effectively and Bartłomiej Danek showing how to document the project to make customer happy.

Working in an agile environment I didn’t cover all the details, missed some points, but let’s face it—this article is done the same way as Haxorz is–by continuous improvements and learning by mistakes.


Last but not least.

After Haxorz our guests had a chance to participate in networking part, visiting our offices and also could see how we work on a day to day basis trying to bring some value to the city we’re operating in and community we have common ideas with.
