Back to original languageAbout Louis
Computer Science Engineer graduate from CESI school, I assist companies as a freelancer in their modern web development and IoT / embedded systems development.
My versatile Fullstack profile in web development, networking, infrastructure, and IoT allows me to work on the entire technical chain, from the user interface to the infrastructure, including connected hardware.
My Areas of Expertise
1. Modern Web Development & Resilient Applications
Creation of applications and showcase websites with Next.js, React, and TypeScript.
Design of tailor-made business solutions (e.g., a complete management and ordering tool for the restaurant industry).
Expertise in Offline-first architecture: development of highly reliable applications, designed from the outset to withstand network outages and ensure absolute service continuity (IndexedDB, SSE, automatic synchronization).
2. IoT, Embedded Systems & Industrial Computing
Firmware development in C / C++ (STM32, STM8, ESP32, Arduino).
Exploration and integration of embedded Linux (Yocto Project) and communication protocols (LoRa, MQTT).
Home automation, sensor measurement, and data centralization (Grafana, Home Assistant).
3. DevOps & Infrastructure Management
Automation and continuous integration via CI/CD pipelines (Azure DevOps, GitHub Actions, Jenkins).
Containerization and virtualization: Docker, Linux servers, Proxmox environment management.
Why collaborate?
With diverse experiences in demanding environments (including a year of apprenticeship at Siemens and an international project), I stand out for my rigor, adaptability, and attention to detail. I approach each project with a problem-oriented approach and an Agile methodology.
