Hello, I am Feryael Justice

FeryaelJustice profile views
Mobile developer specialized in Android, building clean, user-centered products with Kotlin, Jetpack Compose, MVVM, and Clean Architecture, besides improving everyday with Compose Multiplatform (CMP) & Kotlin Multiplatform (KMP). I also work as a fullstack web developer with a strong frontend focus, creating modern web experiences with React, Vue, Laravel, TypeScript, and Node.js.

About Me

Hello and welcome. I am Fernando Gonzalez Serrano, also known as Feryael Justice, a developer from Spain focused on building polished digital products across mobile and web.

My main focus is Android development. I enjoy creating modern, secure, and scalable applications with strong architecture, clean code practices, and careful attention to user experience. I have professional experience contributing to enterprise and banking environments, including Android work delivered in collaboration with NTT Data.

Alongside mobile, I am also a fullstack web developer with a frontend-oriented profile. I have worked with Laravel, Vue.js, React, TypeScript, JavaScript, and backend integrations, always aiming for usability, performance, and maintainable code.

My technical profile is reinforced by formal training in Artificial Intelligence and Big Data and a completed specialization in Cybersecurity in IT Environments, which gives me a broader perspective on secure software, automation, and the future of intelligent products.

I am always interested in building meaningful products, collaborating with solid teams, and taking on challenging opportunities in Android, frontend, and product-focused engineering.
