What I'm looking for

I'm looking to build scalable web products where I can apply full-stack engineering, clean architecture, secure APIs, performance optimisation and DevOps practices in an Agile environment.

At DecliTech, I build Declingo, a scalable language-learning platform using Next.js, Node.js, MongoDB and TypeScript. I develop authenticated REST APIs, role-based access control, reusable components and Docker-based environments.

I've delivered full-stack products across tourism, electric-vehicle charging and medical appointment booking. My work includes real-time messaging, secure JWT authentication, admin dashboards, Google Maps integration, Spring Boot services and documented REST APIs.

I also build SaaS and open-source products, including MyCoachTN, IAresume and an Express.js authentication package. My projects cover subscriptions, payments, scheduling, AI-assisted resume generation, PDF exports and production-ready e-commerce.

I focus on clean, tested architecture, performance optimisation and reliable delivery in Agile teams. I use monitoring, CI/CD and secure backend practices to ship web applications that scale.
