Donatien Oussa | Frontend Engineer
I’m a Frontend Engineer specializing in the design and development of high-performance, scalable, and user-focused web applications.
I help startups, SMEs, and product teams transform their ideas into reliable web applications, from MVP to production-ready solutions.
My approach combines clean architecture, performance optimization, and modern UI development to deliver applications that are maintainable and built to scale.
I build web applications using a modern, proven, and production-ready frontend stack:
- React & Next.js → Modern web applications (SSR, performance, scalability)
- Angular → Structured and enterprise-grade frontend applications
- TypeScript → Type-safe and maintainable codebases
- Zustand & TanStack Query → Efficient state and server-state management
- Supabase & Firebase → API integration and backend services
- Tailwind CSS → Clean, consistent, and responsive UI
Each technology is chosen to ensure performance, scalability, and long-term maintainability.
I design and develop frontend solutions tailored to real product needs:
- Web application development (React / Next.js / Angular)
- Frontend architecture and scalable codebases
- API integration (REST, Supabase, Firebase)
- Performance optimization (loading, rendering, UX)
- UI implementation from Figma designs
- Deployment and production setup (Vercel)
All projects are delivered with clean code, clear structure, and scalable architecture.
I collaborate with:
- Startups building modern web products
- SMEs and entrepreneurs launching or improving web applications
- Product teams looking for a reliable frontend engineer
- Strong specialization in frontend engineering
- Mastery of React, Next.js, Angular, and modern tooling
- Focus on performance, scalability, and maintainability
- Clean architecture and structured codebases
- Clear communication and efficient delivery
I don’t just build interfaces.
I deliver robust, scalable, and well-structured frontend applications designed to grow with your product.
Each project is treated as a long-term product, not just a one-time delivery.
