About Javier

Hello! 👋

I am a freelance programmer with over 15 years of experience, specializing in the development of native mobile applications for iOS and Android, as well as in the creation of robust and scalable backend solutions, using the Vapor framework.

I have collaborated on projects for sectors such as banking, energy, health, and tourism, adapting each development to the specific needs of my clients. I work with modern technologies like Swift, Kotlin, and Vapor, integrating databases such as MongoDB and PostgreSQL, and deploying on cloud platforms like AWS and Digital Ocean.

I have worked in startups developing applications for third parties (Cuadernillos Rubio, Consum, etc.), video games (Hungry Monster for the company Belros), as well as in large companies, developing a BaaS for internal use in the company, both applications and video games developed by Pyro Mobile. I have also developed Android applications (official application of the series Águila Roja, for TVE), as well as iOS application development for the banking sector.

My approach combines technological innovation with a firm commitment to quality, meeting deadlines, and delivering solutions that drive the success of each project.
