Their Android app streams music, talk and sports at continental scale. Since 2023 I've led the app's in-app purchase features: Google Play and Amazon Appstore billing, multi-tier subscriptions, upgrades and downgrades, free trials.

Two years in the Content Discovery team: the collection and content-detail screens hundreds of millions of people scroll, on anything from phones and tablets to FireOS TVs and ChromeOS laptops, with sustained accessibility work throughout.

Swile's employee-benefits app was live and growing fast when I arrived. I led instant chat inside it from first specification onward: prioritization, architecture, and the development of a real-time messaging stack. Priorities later shifted and the feature never launched.

Five years of consulting and development: tech lead on teams of 2 to 8, TDD and clean-architecture culture, security and performance audits, B2B and B2C apps with regional to European reach. Also: Google Glass demonstrators for a luxury house, the USI conference app, published articles on ProGuard and mobile code sharing.
Along the way, I also worked with Virtuo, BNP Paribas and Match.
The lab
in development
Private photo and video sharing for family and close friends, privacy-first and hosted in Europe. It started where these things start: kids, a phone full of photos, and no good place to put them. Built from an empty repository: Ruby on Rails backend, a Kotlin Multiplatform shared library, native Android and Apple apps. It's also my R&D lab, where I explore what client work hasn't asked of me yet: video transcoding, passkeys, hardening a server exposed to the internet…
About
I'm Louis Davin, an Android engineer in Lille, France. I trained at OCTO Technology in Paris: software craftsmanship, agile methods, consulting. Since then the work has alternated between long engagements and short, focused ones, always native, and increasingly across the whole stack.
Away from client work, I co-founded the Lille Android User Group, published on ProGuard and mobile code sharing, and build home-made IoT sensors for the house. At home, two small kids keep the days full.
Day to day I work remotely from France. A few times a year I make a point of being in the room with the people I work with, and I like engagements to plan for it.
