I build secure banking software, mobile apps, APIs, and automated cloud deployments.

I'm building and maintaining a NextJS web application and a native Kotlin application with Jetpack Compose at Datafast Ecuador, while automating AWS deployments through CodePipeline, CodeBuild, and CodeDeploy.

At Topaz Ecuador, I developed Java and Spring Boot microservices and REST APIs integrating fraud prevention and facial recognition tools to strengthen transactional security. I also delivered mobile features with Flutter and React Native, managed Google Play Store and Apple App Store releases, and implemented Azure CI/CD processes.

I've supported internal software, automated operational processes, and bring a computer systems engineering background with an interest in game development, e-sports, and technology.
