How many team leaders do you think there are at Allegro? Earlier this year, about a hundred of us had the chance to meet in person for two days. We tackled company-wide technical challenges, exchanged experiences and discussed the way we and our teams work. We encourage you to read our story since it offers a glimpse at the inner workings of our company and its culture.
After 5 years of developing and maintaining Hermes, we are very excited to announce that version 1.0 has been released.
A modern look and fully mobile-friendly design — this is how we created the new version of ads.allegro.pl. Unfortunately, several hundred tests did not protect us from errors. The last straw was when a simple but very annoying problem appeared in production. We decided to start a revolution. We considered Flow, but ended up adopting TypeScript for Allegro Ads.

What kind of builders do you use in your tests? Do you use the old good builders where properties are set by a withProperty method? Or maybe, you use builders that make use of closures? As soon as I joined my team, I found out that there is another approach to test builders, and it embraces maps. It seemed innovative, but after a while, it became annoying legacy code. After one of the debugging sessions, I decided to get rid of it, but the monster fought me back.
Since the beginning of my career as a Java developer, keeping up to date with Java was fairly straightforward. Big releases came every few years, causing a bit of mayhem in tooling, IDEs and job interview questions. However with each release there was a lot of time to adjust and migrate to newer versions. With Java 9 things have changed. The so called new release cadence was announced by Oracle. Instead of releasing a new major version each few years, we will get one every half year. This poses a lot of challenges to companies using Java in production, developers and the community as a whole.
