I help companies and startups in thedesignanddevelopment of high-performance, reliable native mobile applications**, as well as in the implementation of the **backendandcloudarchitectures that support them.
Specializing in nativeiOS and Android**, I work on projects ranging from mobile **MVPs(0→1) to high-traffic applications, focusing on code quality, performance, maintainability, and user experience. I also have extensive experience in integrating APIs, distributed services, and CI/CD pipelines, which are essential for modern mobile products.
What sets me apart is anend-to-end approach**: I can design the architecture, develop natively, structure backend communication, and **support product teamsin their technical decisions. Having held technical lead and CTO roles, I know how to make the right trade-offs to deliver quickly without sacrificing quality.
I typically work on:
native iOS / Android development
refactoring or modernization of existing mobile applications
API design and backend integration
0→1 support and scaling
improvement of production performance and stability
My goal is to deliver robust, fluid, and scalable mobile applications, aligned with product needs and the real constraints of the teams.
