Available to hire
I am Axel Hernández Domínguez, a Computer Systems Engineer with a passion for full-stack development, game design, and mobile applications. I specialize in backend technologies such as Java Spring and Node.js, and frontend work with JavaScript, jQuery, AngularJS, Angular 8, and Ionic. I also manage databases including MySQL, Oracle, PostgreSQL, and MongoDB, and I develop games using Unity 3D (C#) and Unreal Engine (C++), with hands-on experience creating 3D models in Blender from 2D references.
I have held roles at IBM, Herasoft, and Nordsterntech Technologies, focusing on Java, React, Kotlin, documentation, and testing with Kibana and Grafana. I have experience with mainframe development (COBOL, REXX) and real-time data exchange via socket backends, and I enjoy mentoring new engineers and pursuing my creative passions in art, storytelling, and game design. I currently reside in Tlajomulco de Zúñiga, Jalisco, Mexico.
