| [Android] - Elaine Dias Batista - How to pick the right mobile technology | If at the very beginning of mobile development (2008) and until recently, we only had official solutions provided by manufacturers which were considered to be serious solutions for creating mobile applications, in 2023 the possibilities have multiplied. Google and Apple have introduced solutions to realize the UI in a declarative way (Jetpack Compose, Swift UI), React Native has a large market share, Flutter continues to grow, and solutions like KMM (Kotlin Multiplatform Mobile) allow the sharing of business code between the two platforms. What solution should you start as a dev? As a business? In this talk, we will present you with elements to help you in your choice by answering the following questions: - Why and how each solution was created? On what basis? By who? - How it works ? How is the code executed? What are the technical limitations? - What are the possibilities for integrating these technologies into a new project? In an existing project? Can we mix these technologies? |
| [Flutter] - Bogdan Hobeanu - Dart & Flutter: A Worthy Duo for Your Upcoming Web App Project? | When mentioning Flutter and Dart, most people think about mobile apps. However, Flutter and Dart can also help with building desktop and web apps.
If you’ve heard about Dart and Flutter but aren’t sure if they could be beneficial for your next web app, this talk is for you. |
| [Cloud] - Rustam Mehmandarov - Building Data Pipelines With Java And Open Source | A few years ago, moving data between applications and data stores included expensive monolithic stacks from large software vendors with little flexibility. Now, with frameworks such as Apache Beam and Apache Airflow, we can schedule and run data processing jobs for both streaming and batch with the same underlying code. This presentation demonstrates the concepts of how this can glue your applications together and shows how we can run data pipelines as Java code, the use cases for such pipelines, and how we can move them from local machines to the cloud solutions by changing just a few lines of Java in our Apache Beam code. |
| [Android] - Adrian Cruceanu, Monica Muntean - Building a Scalable Multi-Product Android Platform | Scaling an Android app from a single-product to a multi-product mobile platform requires careful attention paid towards its overall architectural framework – particularly when moving towards a single codebase and multi-product platform. In our upcoming talk we’ll explore both the benefits and downsides involved in managing several individual apps versus implementing one codebase supporting many distinct products simultaneously. With our insights you’ll gain a comprehensive understanding of how to build an architecture to enable multiple products while avoiding the issues that come with managing multiple apps. Join us for an insightful discussion on building large-scale mobile platforms! |
| [Flutter] - Alex Bordei - 🌐 Flutter & IoT: Mastering Sensor Integration 📲🔌 | Discover Flutter’s new frontier in IoT at DevFest Bucharest! 🌐📱 Learn to integrate and read sensors, transforming apps with real-world data.

| [Cloud] - Marton Kodok - BigQuery Remote Functions for Dynamic Mapping of Emobility Charging Networks | We will be showcasing the capability of BigQuery Remote Functions to extend a company name database, by pulling their public address, storing as a new column, then geocode into coordinates. Our presentation will demonstrate how Remote Functions enables us to leverage the Places API and Geocode API, in order to visualize on Looker Datastudio a database of company names who installed public charging points for electric cars. The analyses will be done on the Romanian Government's Electric Up program's approved project list for solar panel and electric charging stations installed. |
| Lunch break | |
| [Android] - Adrian Coman - From Monolith to Modular: Pago's Approach to App Modularization and SDKs | This will be a presentation about the technical approach of splitting a monolith app that would build in 5+ minutes. We'll look at how we split it into modules and those modules into even smaller modules. The focus will be on how this approach streamlined internal development processes and enabled the creation of standalone SDKs for partners interested in integrating specific Pago products.
The presentation will also cover the strategic planning behind the refactoring and rewriting efforts, outlining the necessary steps and safety measures. You will gain valuable insights and learn practical tips and tricks for enhancing your build times, workflows, and apps. These insights are applicable whether you're working on a product or in an outsourcing company. |
| [Flutter] - Mangirdas Kazlauskas - Control your Flutter application on the fly with Firebase Remote Config | Real-time updates, A/B testing, app personalisation - what if I told you that you could enable these powerful features in your Flutter application with minimal development effort and without any costs? Firebase Remote Config is a free service that enables changing the behaviour of an app remotely without publishing an app update. In this talk, I will cover multiple real-world use cases where Firebase Remote Config could help you while building Flutter apps.
The talk will revolve around an example app that will be gradually extended with multiple Firebase Remote Config features. Specific use cases covered in the talk:
1) App configuration values;
2) Notifying users about a new app version;
3) Feature toggling (enabling/disabling features on the fly, staged rollout, etc.);
4) App personalisation (using different config values based on conditions - platform, language, region, date/time, etc.);
5) A/B testing;
6) And more! |
| [Cloud] - Lucian Gruia - Neural networks and the emergence of Learning | Neural networks are now one of the most powerful impact drivers globally. They make revolutions in entire industries alongside advancing natural language understanding.
Being foundational to deep learning, neural networks enable unprecedented data processing sophistication & transform artificial intelligence by mimicking human brain structures.
Beyond their vast applications, there's a deeper discussion: While we might lean on AI for many tasks, who builds the AI? How can we design them right, thus affecting massive tectonic changes?
Understanding neural networks isn't merely academic—it's understanding the very fabric of our digital future.
## The agenda:
* What a neuron is and how it functions.
* The fundamental principles behind neural networks and their role in constructing artificial intelligence engines.
* Construct a neural network programmatically.
* Illustrate how learning emerges.
* Emphasis on the differences between learning and data storage.
* Explore concepts such as knowledge, understanding, and reasoning.
* Discussion on the different types of learning. |
| [Android] - Gabriel Stefan - Instant(App) Gratification: What, How, Why? | In the last few years we’ve seen a trend of short-form content: TikTok, Threads, Shorts. People want their content now! What if there was a way to deliver your app instantly and seamlessly, without users having to install it? Enter Instant Apps! In this talk we’ll go over what instant apps are, why should you consider them as your next step in enriching your user experience and raising your conversion rates and how did we go about developing and fitting it into one of our client’s app: Mazed.
