Imagine you are designing a B2B service that will serve millions of businesses. This service will have dozens of different microservices with their own data, which can contain millions of records. How do you design such a database? Why is sharding not always the answer? What other options are there for such an architectural solution? I'll tell you how we at Uspacy came to serve thousands of small databases instead of a few large ones, what we've encountered and what we plan to face)

Localization and Internationalization are two core concepts to create sites and applications for international users. In creating and working on such international websites I repeatedly made or found the same mistakes and pitfalls that made creating international websites much harder than necessary. Let me take you on a tour through the concepts and common problems that arise and see how they can be solved with less headache than you might think.

In this talk, I'll give a quick introduction to LLM and how to use it in a PHP application. I'll show some examples using the LLPhant project including a retrieval-augmented generation (RAG) system using a local LLM (Llama 3) and Elasticsearch as a vector database.

I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Software performance engineering (SPE) aims to build predictable performance into systems by specifying and analyzing quantitative behavior from the beginning of a system to its deployment and evolution. We should also apply this thinking to the data portions of our applications and systems. Performing data operations with Entity Framework Core 8 can seem simple, but there is a hidden part of this framework that can allow developers to unlock the performance users expect. We will lean into this, explore those EF Core features, and leave the talk as better developers.

<p>In this talk, we will get acquainted with TechEmpower Web Framework Benchmarks, consider generalized (programming language-independent) approaches to optimizing a web application and its environment to achieve extreme loads, and most importantly, how some of these things can be applied in practice in your projects. </p>
