Talks I gave
Build vs. Buy: software edition
Internal - Octobre 2025
For a while I wanted to give this talk because I cared about its subject a lot — it's about the classic question of whether to buy an existing software solution or build your own. Opinions on this topic are often divided, with a slight preference toward “Buy.” As someone who tends to lean toward the “Build” side, I’m often challenged on that perspective. So I decided to prepare this short talk — not to convince anyone to change their mind, but to explore the topic in depth and better understand the reasoning behind both approaches.
Rex on TDD: from someone who had never been into 😅
Internal - Decembre 2024
In this talk, i've demonstrated how Test-Driven Development (TDD) can accelerate development and ensure reliability when working on critical, complex components of an iOS application. Using a GPS track editor as an example -a tool for bikers and hikers to create custom paths with GPS coordinates— I talked about the evolution of a basic editor into a feature-rich application. During the developement process, TDD became essential at key stages, helped me achieve stability, maintainability, and confidence in my code.
From a third party map SDK to DktMaps: an abstraction interface for a better usage
Internal - Mars 2024
When I joined Decathlon, our goal was to integrate a map SDK that supported advanced map interactions and turn-by-turn navigation. To make the Mapbox SDK easier to use within our ecosystem, we built an abstraction layer around it — resulting in DktMaps, a developer-friendly interface that simplifies data interactions and improves integration consistency. In this talk, I discussed how Mapbox works under the hood, how we streamlined its usage through our abstraction layer, and how we integrated turn-by-turn navigation — all while ensuring full SwiftUI compatibility.
