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 using n8n and agentic AI systems.

My recent work includes penetration testing, API security development, and secure backend design at Linguistic Communication (QUALIOPI-certified), where I’ve contributed to scalable, compliant infrastructure for EdTech platforms. Alongside engineering, I teach at IPI école d'informatique | IPI Paris and American Business College (ABC)—both under the IGENSIA Group—covering a range of technical and management modules including Agile, Lean Methodology, Scrum, Digital Strategies, Web Development, Networking, Software Lifecycle, DevOps, and IT Audit. My teaching connects industry best practices with real-world application, helping students develop both technical mastery and strategic awareness in today’s cybersecurity-driven landscape.
