What I'm looking for

I'm looking to build modern, secure, user-focused mobile or web products where I can apply clean architecture, MVVM, performance optimization, and collaborative agile development.

I've built Android features for a large-scale banking app at Exis TI (Altia), using Jetpack Compose, MVVM, Kotlin Coroutines, and Flow under quality, security, and performance standards.

At Homerti, I developed and maintained internal PHP, Laravel, and Vue products, improving performance and user experience by 60%. I've also developed enterprise software at Tec-Soft, contributing to a 20% product-quality improvement.

I build clean, user-focused applications with Clean Architecture and MVVM, spanning Android, backend APIs, and full-stack web development. My projects include MiraiLink, a Google Play social app, and Hotel Aura de Mallorca, a climate-aware booking website with security features including 2FA and Google reCAPTCHA.
