I am a computer systems engineer specialized in programming languages and databases, networking, electronics, and technology. I enjoy turning theoretical knowledge into practical solutions for everyday life. With over 15 years of experience, I have dedicated my career to building high-performance systems based on multiple architectures and stacks with the idea of bringing down to earth abstract ideas or concepts and convert them into real-world applications. I believe technology that works for people is the key to achieving a higher quality of life and I am excited to contribute to projects that improve day-to-day living. In Mexico, I built time attendance SaaS systems; I worked for the Oil&Gas industry building control and monitoring systems. In China, I worked mostly on the E-Commerce sector building platforms for international companies so that they could sell their products on that market. In Europe (mainly Germany and Spain), I've been building digital marketing solutions for the vehicle industry. Whether it is debugging legacy interfaces or designing new cloud-native services, troubleshooting intricate system bottlenecks or architecting new event-driven services, my approach is always defined by a proactive and curious mindset.
