Fullstack Web App Development

Frontend Architecture

To build responsive and reactive interfaces, I rely on Atomic Design, DDD (Domain-Driven Design), a mobile-first approach, and user-centered UX methodologies.

Backend Architecture

Backend business logic development using Node.js or .NET Core, following SOLID and KISS principles, and applying architectures like the Repository Pattern, Service Layer, and Clean Architecture to ensure maintainable and testable code.

I leverage microservices and serverless infrastructures for lower costs and optimal scalability.

Performance & SEO

I improve the performance of your websites and applications by optimising resources, reducing network requests, and implementing effective caching strategies.
