Back to original languageAbout Gwendal
Hello! I'm Gwendal. With a degree in Digital Systems, IT, and Networks (BTS SN-IR), I specialize in the behind-the-scenes: the plumbing, Back-End logic, infrastructure, and security.
Thanks to my technical background, I understand what's happening under the hood of your servers. I'm not afraid to dive into existing code, perform reverse engineering, or diagnose complex failures to unblock your business.
My services:
- Back-End & API Development: Design of robust services (Python, Node.js).
- Scripting & Automation: Custom scripts (Python, JS) to connect your tools (ERP, CRM, MySQL/MariaDB databases) and automate your tasks.
- Network & Protocols: Data streams (MQTT/Mosquitto) and management of local or remote servers.
- Emergency Maintenance & Bug Hunting: Server down, application crashing, or broken API? I intervene quickly to audit, secure, and repair.
- Why work with me?
- I am discreet, meticulous, and demanding about the reliability of my deliverables. You entrust me with a technical problem or specifications, I isolate myself, I solve it, and I deliver a secure tool that works. No fuss, just results.
Available immediately for one-off missions, urgent fixes, or technical assistance.
Shall we discuss your current blockage?
