But sooner or later they begin to slow down — like driving through a city during rush hour, when every street hides another traffic jam. In this presentation, we'll explore where queue wait time actually appears in our systems, how to spot them and how to fix them. All insights come straight from Production.18:15 – 18:45 ❓ Q&amp;A with Mateusz18:45 – 19:15 🤝 Networking Break19:15 – 19:35 ⚡ Presentation #2: Piotr Mroz (commercetools) — TBUDescription TBU19:35 – 20:00 ❓ Q&amp;A with Mateusz20:05 – 21:00 🍕 Networking &amp; Pizza🎙️ Meet the SpeakersMateusz  Nalepa (Allegro ) Mateusz is a software engineer with nine years of commercial experience. His work focuses on building efficient, well-designed systems, with a particular emphasis on core software engineering principles that drive performance and scalability. He believes that "MS Paint" and the phrase "it depends" are the absolute best tools for explaining complex programming concepts. His favourite AI prompt - "Hey, explain XYZ to me like I’m a 6-year-old"—helps him quickly find a solid point of reference. At work, he enjoys sharing his knowledge and is always eager to onboard new team members. In his free time, he performs in theater and plays the piano.Piotr Mróz (commercetools) Principal Engineer helping teams build fast, scalable, and reliable cloud services. He leads performance initiatives across commercetools, focusing on automating load and resilience testing, optimizing JVM performance, improving Kubernetes scalability, and promoting data-driven engineering. Outside of work, he trains in amateur kickboxing and enjoys bouldering.Photos may be taken during the event and published on the social networks and websites of SII, Sabre, Pega, IG Group, and Allegro for promotional and marketing purposes.
