Building high-quality mobile and web applications for modern businesses

Freelance Software engineer & Problem Solver

Hello! I'm Manuel 👋

I’m a freelance software engineer from Barcelona specialized in building scalable, high-quality web and mobile applications for startups, scaleups, and established companies.

With over 8 years of professional experience, I’ve partnered with product teams, founders, and CTOs to design, build, and deliver reliable software, from early-stage MVPs to large-scale production systems used by millions of users. I combine strong technical expertise with a product mindset, ensuring that what we build is not only well-engineered, but also aligned with real business goals.

My work spans the full development lifecycle: architecture, frontend and backend development, performance optimization, CI/CD, and deployment. I’m particularly experienced with modern JavaScript ecosystems (React, React Native, Next.js, TypeScript) and enjoy collaborating closely with design, product, and business stakeholders.

I’m always open to discussing new projects, consulting opportunities, or long-term collaborations.
