JIT Compiler & Spring Boot 3, ready or not!?

25/10/2022

A Barcelona Jug meetup was held in Glovo offices on the 25th of October, 2022 about the JIT compiler and Spring Boot 3. André Lopes Nogueira, Backend Software Engineer at Glovo, speaking about the JIT compiler. Abstract: The JIT(Just-In-Time) compiler is a key component of Java Virtual Machine(JVM) that is responsible for performance optimizations at runtime, applying advanced techniques to boost applications' performance. In this talk, we will provide an overview of the Java JIT compiler: its architecture, how it works, what the different optimization techniques are when it is triggered, and how we can inspect it live. Speaker: Andre Ricardo Lopes Nogueira, Backend Software Engineer at Glovo since 2019 and previously a computer science researcher at the University of Lisbon for 6 years, focused on dependable and intrusion-tolerant systems. Next up, Abel Salgado Romero from VMWare spoke about: Spring Boot 3: ready or not? Abstract: Spring Boot 3 will be out on the 24th of November, just around the corner! With it, many improvements and the long-awaited Spring Native Support. In this session, Abel will try to answer what to expect from it and what it means for your current and future application.

Kafka: Let it Flow

12/5/2022

Nowadays, data is the most valuable product a company has, and being able to work over it with flexibility, security, and reliability, to get the most out of it, is a must. Becoming a data-driven company is not simple but is key to success. In this online session, we covered the basics of how Kafka can help us during this journey. We presented different examples to explain Kafka's capabilities and explored how to leverage high-level tools such as Kafka Streams API and ksqlDB to add more brainpower to our data in motion. This was our first Tech Meetup in Madrid together with MadridJUG where our experts shared their knowledge about Kafka. Note: the talk starts in Spanish but the content is in English.

Frontend at Glovo

26/4/2022

In April 2022, we hosted our Tech Talk #2! The topic was Frontend at Glovo. Angel Sola, Software Engineer at Glovo, talked about how Complex State management is -arguably- one of the keys to scalable applications. There are many libraries at our disposal, but little bibliography is available on what makes a robust state management system, and some guidelines to get it right are needed. In this talk, we’ll take a step back and analyse the keys to good state management, including taking a quick tour of its history. After this talk, you should feel empowered to make the right choice for your next app’s state management. Dan Neciu Stroe, Software Engineer at Glovo, presented how to build Scalable Components. Customer Software Development requires shipping fast, reliable, A/B testable code and design. This is how we at Glovo are building multiple variations of the same component and shipping it to millions of users in 26 different countries.

Modern Android at Glovo

22/3/2022

On March 22nd, we hosted our first Tech Talk of 2022, where we had the chance to share our learnings in the tech field and connect and network with the public. The topic covered was Modern Android at Glovo: what we learned introducing Jetpack Compose and Hilt in our apps. Compose is a UI declarative framework that enables you to build complex UI with little effort. Let’s look together at its APIs and the basic notions you must know before starting using it in your app. Why Hilt? We already had Dagger, did we really need another dependency injection library? In this talk, we will try answering these questions by starting from what Hilt promises and then diving into how it works.
