About Me

I develop and optimize interfaces with a strong focus on accessibility and reliability. I have over 4 years of experience as a Full Stack Developer, actively contributing to technical and product decision-making from both frontend and backend perspectives. I focus on ensuring the performance, stability, and quality of every product I work on. I’m driven by staying up to date with the latest technologies and taking on challenges that foster my professional growth. I enjoy being part of the full development cycle of products, supporting their evolution, and working with a long-term vision.

How I can help you

Build web pages

From concept to launch, I build fast, accessible, and optimized sites so you don’t lose customers to slow load times or poor usability.

Build cross-platform applications

A single codebase for web, iOS, and Android, reducing costs and time-to-market without compromising quality.

Optimize and scale your existing platform

I enhance performance, security, and stability so your product can handle more users and deliver a seamless experience.

Audit your code and architecture

I identify bottlenecks, bad practices, and security risks so you can prevent costly issues before they arise.

Integrate technologies and APIs

I connect your product to external services (payments, authentication, analytics) to expand functionality without reinventing the wheel.

My Projects

Here are some of the projects I’ve worked on.
