Join us for **BipTalks Engineering Meetup**, where we’ll explore how to work *with* your database – not against it – through real-world engineering examples and practical insights. Using concrete scenarios from production systems, we’ll show how often-overlooked aspects of **relational database design and usage** can have a major impact on application performance. You’ll learn how to spot common pitfalls, understand what happens **behind the scenes in a database engine**, and make architectural decisions that help your system scale and perform better. The talk is **database-engine agnostic** and valuable for anyone working with data. 💡 **What to expect:** * **Real-world database insights** – See how seemingly small decisions in database usage can significantly affect performance and stability. * **Actionable design advice** – Learn how to recognize common pitfalls and make architectural choices that work in favor of your applications. * **A deeper technical perspective** – Gain a clearer understanding of how relational databases operate internally and why they behave the way they do. * **Networking & fun after the talk** – Connect with fellow engineers and Infobip developers, enjoy food and drinks, try out the **F1 simulator**, and win tickets for the **Shift conference** 🏎️🎉 **🎤 Speaker:** **Borna Biljan**, Principal Engineer @ Infobip Borna Biljan is a Principal Engineer at Infobip with over 15 years of industry experience. He holds a Master’s degree in Electrical Engineering and Information Technology and has built strong expertise in designing and developing complex systems. Currently, he works as a back-end engineer focused on **high-throughput, highly available, low-latency systems**, most often using **Java technologies and MS SQL Server**. After the official part of the program, stay with us for **great conversations, refreshments, and hands-on fun with the F1 simulator**! 🍕🥤 🎟️The event is **free**, but the spots are limited so please register here: [Bip Talks Zagreb - Infobip](https://www.infobip.com/hr/c/biptalks-engineering-meetup)
