| 9:30 AM | [Mobile] - Ahmed Tikiwa - Channel me perfect: the importance of app notifications and delivering them via notification channels | Notifications play a pivotal role for any user-facing application as it gives your users the necessary updates when required. However, if they are not used correctly, they can end up being an annoyance for your users as opposed to something they need. Android has Notification Channels which assist in placing notifications into groups or categories, think of, "Urgent Notifications" vs "Promo Notifications". By placing notifications into channels, important notifications can be received into the right channel and non-trivial notifications can be optionally received and the user can decide to receive them, or not, without compromising receiving important notifications. This can be very beneficial for a delivery app for example - where delivery updates are the important notifications and promo notifications are the trivial, which can be turned off. |
| 9:30 AM | [Web] - Paul Negoescu - Clean Code for Frontend AIs | What are AI chat-bots currently capable of? Will they help us be better developers or will they even replace us? As a trainer, engineer, and architect myself I wanted to explore to what degree will AI be able to mess with my job. Will it make evaluating students or job candidates impossible? What are the limits, how can I as an interviewer throw a wrench into the wheels of someone using AI to “beat” my interview questions? How can I ensure that students taking my courses will play fair? How can I get help from an AI and generate code that is not only relevant but also clean and efficient? During this presentation we will look together at some code examples, where and how AI failed to produce maintainable code and even how it can fail to produce working code. Let’s try to answer some of the above questions together, in the short time we have. |
| 9:30 AM | [Cloud] - Natalie Godec - Balancing tight security with fluid devex, powered by GKE | The most secure server is one that is disconnected from the Internet and unplugged. And the most convenient environment for devs is where they have admin access to production and the freedom do what they want. How do you marry the two? Let's look at a real-world scenario where we built a cloud-native fintech platform on GKE. The vision? A robust, flexible, and secure foundation that supports SOC2-compliant deployments and empowers developers to be as productive as possible, contrary to the typical for the financial sector blown-out processes and approval chases. This solution is powered by Google Kubernetes Engine (GKE) and the cloud's niftiest security tools from the Secure Supply Chain toolkit. |
| 10:15 AM | Lunch break | |
| 11:15 AM | [Mobile] - Radu Radu Marin & Radu-Ioan Ciobanu - Watt’s Draining Your Battery? | There’s no worse feeling than your phone’s battery draining when you need it the most. As developers, in our quest to deliver the most exquisite mobile experiences, we often overlook the fact that our apps are running on battery-powered devices. The more we crank it up, the more we sacrifice battery life. And this is a compromise that users aren’t always willing to make, so we shouldn’t either. Let’s take a look under the hood of Android’s power management and better understand how it works, and, more importantly, how we can work with it. From idle states to Doze, we’ll uncover the mechanisms that are currently used to preserve battery life. We’ll see that performance doesn’t need to be compromised for extending battery life. From proper background behavior to smarter resource usage, you’ll learn best practices on how to measure and optimize the power consumption of your apps. You’ll also find out how you can keep your users more informed and engaged, and they’ll thank you for it! |

| 1:00 PM | [Cloud] - Joshua Fox - Taking Machine Learning to production: Vertex MLOps for speed and efficiency | I have worked with many startups which emerged from university projects. They often run on a single virtual machine, which is what works for research.
However, as the system scales and enters production, automation becomes crucial. Google Vertex can radically streamline this process. For example, model training is more efficient with a managed service that automatically scales compute resources based on your training needs, eliminating the cost of idle resources – as happens when you use a Jupyter Notebook or a VM for training.
We’ll cover other parts of the ML process with Vertex and other Google Cloud services, including development, hypertuning, deployment for inference, tracking model performance, and defining the entire pipeline.
The hard part is deciding when to switch. Learning new services and migrating to them takes precious time that a fast-moving startup cannot afford. But If you stay too long with the simple architecture, you end up building components yourself, and eventually get locked in. So, after reviewing the Google Cloud services you can use, I will explain the key decision points for when to adopt each of the services. |
| 1:45 PM | [Mobile] - TBA | |
| 1:45 PM | [Web] - Bogdan Hobeanu - The Dart stack: why code twice when once is nice? | You’ve built your Flutter app, and now you need a backend. Who you gonna call? Dart might be the answer! Tired of switching between different languages and tools? Can Dart simplify full-stack development and let you use one language for both frontend and backend? Let’s find out together. |
| 1:45 PM | [Cloud] - Marton Kodok - Vector search and multimodal embeddings in BigQuery | BigQuery allows you to generate multimodal embeddings and perform vector searches directly on your data without complex preprocessing steps. Simplify the process of finding relevant data, identifying patterns and trends, and clustering similar objects together. Learn how to generate embeddings using familiar BigQuery SQL syntax with multimodal inputs (text, images, audio). We’ll then review how to use BigQuery’s vector search capabilities to explore data in new and innovative ways, leading to faster decision-making and improved insights. |
