Krakow, Poland, 25 - 27 August 2021
Writing computer programs has been my passion since I was a kid, but back then I didn't think it would be my career choice. I studied Molecular Biology and Computer Science at College of Interfaculty Individual Studies in Maths and Natural Sciences at Warsaw University. After graduating in Molecular Biology I decided to pursue my career in IT. I have been developing web applications in Java and JavaScript for more than 10 years now. I worked for Capgemini, Polish National Center for Research and Development, Bunge. In September 2013 I joined Vaadin, the Finnish company behind the framework with the same name, where I worked as a programmer and trainer, developing, among others, Vaadin Designer. In spring 2018 I left Vaadin to explore opportunities in Poland and around the world. In May 2019 I joined Atlassian, where I develop one of the most popular tools used by software engineers all around the world – Jira. My speaking experiences include Devoxx.PL, Gr8Conf, Liferay DevConf, and Confitura.
A tale from the trenches: we initially got our DB schema wrong and now we have millions of users…
Conference
How to safely perform schema changes like changing the primary key of the table on a scale of millions of users and thousands of tenants and not have an incident? How to not make SREs angry with you for being woken up in the middle of the night? This talk is based on real-life events, any resemblance to actual products might not be coincidental :)
Scheduled on Thursday from 11:40 to 12:30 in Room 3
