LEFEBVRE
full-stack developer · @Loule95450
Tech early adopter with a hacker's bias for shipping things that are slick and fully optimized. I build end to end - from data layer to the last pixel - and I like wiring the physical world into software, whether that is a car, a home, or a pair of glasses.
Stack
Selected work
Première Action
A financial-education platform that turns investing into plain language - articles, fundamentals, and a clean reading experience.
Next.jsTailwindSupabaseVercelTeslaConnect & Undrive
Integrations and companion apps for my Tesla Model 3 'Fabia' - live state, controls, and small automations the stock app never had.
Tesla APITypeScriptAutomationHACS-Nexecur
A Home Assistant component that brings a Nexecur alarm system into the smart-home graph - arm, disarm, and read state locally.
Home AssistantPythonHACSai-sdk-provider
A custom provider for the AI SDK - wiring a model backend into a typed, streaming interface that drops straight into apps.
AI SDKTypeScriptStreamingnew-Alignwin
A window-alignment and layout utility - keyboard-driven tiling that snaps a messy desktop back into a tidy grid.

Home lab & hardware
Home Assistant runs the house. Most of my tinkering lives here: gluing devices together, teaching them to talk, and pushing new wearables to do more than they shipped with.
Home Assistant core
The hub everything plugs into - Withings health data, a robot vacuum I named 'Aspiropoutch', and the coffee machine, all on one local graph.
Tesla 'Fabia'
My Model 3 wired into the same system through TeslaConnect and Undrive - state, climate, and automations on my terms.
Meta Neural Band & Ray-Ban
Early-adopter territory: experimenting with gesture input and wearable cameras as a control surface for everything above.
Custom components
When an integration doesn't exist, I write it - like HACS-Nexecur - so a device stops being a silo and joins the rest.
