Tristan Michel

Full-Stack Developer on a permanent contract at SVL, an Angers-based company specializing in online sales, I managed the entire technical development of two PrestaShop e-commerce sites, from performance optimization to application security.

E-commerce & PHP Development:

Design and development of custom PrestaShop modules in PHP to extend the platform's native functionalities: management of specific business rules, automation of internal processes, integration of payment gateways. Optimization of SQL queries (MySQL) on large product catalogs, significant reduction in front-end loading times.

Product 3D Visualization:

Development of an interactive 3D visualization module directly integrated into PrestaShop product pages. Loading of GLTF/GLB models, orbital camera controls, optimized WebGL rendering via Three.js to offer an immersive shopping experience.

Internal Ticketing System:

Architecture and complete development of an internal ticketing tool from scratch: Node.js/Express REST API, relational database, React management interface. Priority management, team assignment, action history, and notification system.

Application Cybersecurity:

Discovery and responsible disclosure of critical vulnerabilities on the PayPlug payment module (SQL injection, business logic bypass). Implementation of OWASP best practices across all developments: input validation, HTTP header hardening, permission review. Audit of third-party modules before deployment.

Infrastructure & Network:

Administration and security of the local network, user access management, and maintenance of internal servers.

Founder of RiberaDev, I design and deliver web and mobile applications from A to Z — from backend architecture to user interface — with a rare dual development/offensive security expertise in the market.

What I concretely bring:

After 6 years on a permanent contract at SVL (PrestaShop e-commerce), I developed custom PHP modules, optimized critical SQL queries, integrated product 3D visualization via Three.js, and architected a complete internal ticketing system (Node.js/Express). I also discovered and reported security vulnerabilities on a PayPlug payment module (injection, business logic).

In parallel, through RiberaDev, I actively practice Bug Bounty (IDOR, XSS, Cache Poisoning, Business Logic Errors) and develop SaaS & mobile apps: Ti'Bazar, a React Native marketplace for the French West Indies (Supabase, geolocation, real-time messaging), and a full-stack SaaS ERP (React + Node.js, CI/CD, microservices).
