About Me

Full-Stack Developer
Cybersecurity / DevSecOps
Cloud Architect

I’m a security-focused full-stack developer and instructor who builds and hardens modern web applications using React/Next.js on the front end and Node.js/Express with PostgreSQL on the back end—balancing scalability, performance, and defense-in-depth. Currently pursuing a Master’s (M2) in Cybersecurity & Cloud Computing at ESILV (Paris) and holding a First-Class BSc (Hons) in Computing from the University of Greenwich, I focus on cloud architecture, DevSecOps, zero-trust authentication, and workflow automation via n8n and agentic AI systems.

Recent work spans penetration testing, API security, and secure backend design at Linguistic Communication (QUALIOPI-certified), where I help ship compliant EdTech infrastructure. I also teach at IPI école d'informatique (Paris) and American Business College (IGENSIA Group), covering Agile, Lean, Web Development, Networking, DevOps, and IT Audit—linking industry best practices with classroom delivery.
