With more than 10 years of experience, I went from working by myself with technologies that I was comfortable with to tasks across different teams worldwide with stacks that I seldom used... I developed the FRONT-END for web apps using React, Angular and AngularJS. Worked as a BACK-END engineer with Java, NodeJS, asp.net(C#) and python. MOBILE-DEVELOPMENT with React Native including Android specific features in an "offline first" asset tracking application. Configured the basic INFRA-STRUCTURE for many projects including containers with Docker and clusters with Kubernetes. Good experience with the AWS environment. I also can handle different types of DATABASES. There were cases in which applications were struggling to complete requests when using relational databases and I got amazing results by migrating/caching specific parts of them to a better fit such as DynamoDB, Redis and MongoDB for those cases. I know good strategies to reduce costs and boost performance with CACHE and COLD STORAGE for major projects. With strong fundamentals, I am very resilient and I will be happy to help you.
