Part traceability for furniture manufacturing
FABRIK · Taller CNC
“Identify and track every part after nesting.” Imports the nesting CSV and the TopSolid STEP into a single viewer: each part with its reference, size and position on the board, linked to its 3D solid.
- Label: generate and stick QR labels, board by board
- Machine: cut the parts on the CNC following the nesting
- Laminate: mark the sheets placed on already-labelled parts
- Assemble: build the furniture step by step with QR scanning and hardware control
- Full traceability of every step of the process

The digital dashboard your car didn't come with
VehicleOS
“Read. Understand. Protect.” Turns the OBD-II port of a twenty-year-old car into a digital dashboard with explained diagnostics, an assistant that interprets real telemetry, and a web fleet panel. Installable PWA: it runs on the dashboard screen, a tablet or a phone.
- Translated diagnostics: it doesn't say P0401 — it names the part that's suffering and lights it up on the car
- An assistant that answers with the actual telemetry of the moment: ranked causes and whether you can keep driving
- Fleet panel: trips, automatic alerts and WebSocket telemetry, with an offline mode
- An Android bridge (Kotlin) is the only process touching the adapter: the screen never touches the hardware

From craft to infrastructure
Full-stack developer and designer with more than two decades delivering websites, e-commerce and custom applications. I've owned the full cycle of hundreds of projects: briefing, wireframes, design, layout, programming, infrastructure and launch.
Versatile and self-taught: I learn from real projects and the free-software community. I pair a solid back-end (NestJS, Node, REST APIs) with modern front-ends (React 19, Next.js, Chakra UI) and AI and ERP integration.

Hours logged to projects in the manager. Many institutional commissions were invoiced without logging hours, so the real dedication is higher.
