Two dry-run presentations from Devoxx this time!

  • Topic 1: Client says your web app works slowly. Now what?

Abstract: You did great job finishing this web app on time and budget. Design patterns, good code coverage, cutting edge frameworks and best CI ever. It goes to production and boom, clients complain it's too slow. They don't really care, if it's best engineering ever, if each view loads 2 seconds. My presentation will give you hints on how to look for bottlenecks. I will also share simple tricks to make the app work faster, or at least seem to work faster.

Speaker: Ola Kunysz

Difficulties level: mid

Language: PL / EN


Ola Kunysz is a programmer with 11 years of experience in software engineering, going it's through all stages, from business analysis to backend programming. Her biggest interest is solving real-life problems and writing code that matters. For 2 years she organised meetups and workshops of Geek Girls Carrots in Wrocław. She enjoys meeting people and working on interesting projects, so you can meet her on hackathons and conferences. When it’s time to relax, she’s offline [with dog(s), playing board games, in the forest, in the mountains]*.

  • Topic 2: GraphQL - when REST API is not enough - lessons learned

Abstract: We all know the REST architectural style to define a good API for your applications. However, REST has its disadvantages and constraints. That’s why Facebook developed GraphQL as an alternative.

In my talk, I will present you some REST constraints and how GraphQL solves them. I will talk about how we implemented GraphQL in our application and why.

Get to know our successes… and failures from the first row.

I'm a software engineer mainly focused on Java and JVM technologies. I write Clean Code usually using TDD. I appreciate Agile methodologies (because they work), automation of everything and NoSQL solutions. I was a reviewer of the book practicalunittesting.com and organiser of chamberconf.pl. Currently I'm a leader of Wrocław Java User Group wroclaw.jug.pl. I'm a speaker at technical conferences: mstachniuk.github.io/talks, trainer in coding bootcamps and Open Source contributor: shipkit.org. I’m working at Collibra.

In my free time I ride snowboard, splitboard, wakeboard and sometimes skateboard. I also enjoy biking, hip-hop music, traveling and winter swimming.
