qoliber Representatives
Jakub Winkler is the founder and CEO of qoliber – a development agency dedicated exclusively to building Magento 2 extensions for other dev teams and solution partners.
As an experienced engineer and contributor to the Magento Association, Jakub regularly shares deep technical insights at conferences like Meet Magento New York, Florida, France, and India.
His work influences how agencies worldwide integrate Hyvä and ElasticSuite – with a strong focus on clean architecture, scalability, and developer experience.
Jakub’s sessions are known for clarity, hands-on examples, and real-world improvements many senior Magento developers apply in their own practices.
Ola Czapiewska stands beside Jakub as the strategic force behind qoliber’s execution. She ensures projects stay on track, Partners stay happy, and priorities are always clear.
With nearly 20 years of experience in media and digital marketing, Ola has led marketing campaigns with monthly budgets exceeding 100,000 EUR - delivering results for brands like Burda Media, TIM S.A., and Media Saturn.
She's known for her precision, timing, and clarity in decision-making. And if you’re at a Magento event, there’s a high chance you’ll meet her - either near the keynote or ruling the afterparty dancefloor.
