Back to original languageAbout Kossi Edem
Looking for a developer who can handle your project from start to finish, from backend to mobile application? I can assist you in designing, developing, and deploying high-performing, scalable, and production-ready solutions.
Specializing in **Flutter, Node.js/NestJS, Laravel**, and Firebase, I develop mobile applications, APIs, and backend platforms tailored to your business needs. I can work on creating a new product as well as taking over, maintaining, or evolving an existing application.
I can specifically assist you with:
- Flutter mobile application development (Android & iOS)
- REST API and Node.js/NestJS or Laravel backend creation
- Database design (PostgreSQL, MongoDB, MySQL, Firestore)
- Third-party service integration (payment, notifications, geolocation, Firebase, etc.)
- Docker, CI/CD setup, and deployment on VPS or Cloud
- Performance optimization, bug fixing, and evolution of existing projects
Throughout my projects, I have developed and published several applications on the App Store and Google Play, designed scalable backend architectures, and supported teams as a Tech Lead. My approach is based on clean code, maintainable architecture, and transparent communication throughout the project.
My goal is simple: to deliver a reliable, high-performing, and scalable product that can sustainably support your business growth.
