Hi, I'm
Master's in Computer Science UCR · Bachelor's in Computing TEC
Costa Rican with over 16 years as a software developer, technical leader, university educator, and freelance. When I'm not coding, I enjoy playing football, tennis, hitting the gym, and hiking.
I started coding mobile apps, then mastered full-stack, led teams, and taught the next generation. I work full-time for companies and, on my own time, take on freelance projects.
Technologies I've worked with
Key milestones shaping my career
I shipped the next generation of the e-commerce product with a full UI and stack redesign from CoffeeScript and Rails to React and TypeScript. Promoted to re-architect applications and modernize the stack, I now lead the decoupling from the monolith, coach teams on best practices, and curate products across Angular, React, React Native, Node, and PHP.
React, React Native, TypeScript, JavaScript, AWS, Azure, Fastlane, GitHub Actions
I led people in QA, Android, iOS, web, and backend for several clients. I owned platform and project structure, code quality, and best practices and drove layered, event-driven, and microservices architectures. I mentored careers, ran code reviews, and led technical interviews while staying close to clients to plan and deliver solutions that moved the needle.
React, React Native, Node, TypeScript, Serverless, AWS, Firebase, GCP, GraphQL, Kubernetes
I architected and built the technical capabilities that powered multiple client projects and ran technical interviews for new talent. I created and led Hangar Lab, where I taught and coached developers on the company stack. I led over 15 projects and more than 50 people for global brands like Nissan, Marriott, Big Rock Brewery, Citi, LegalShield, and Coaching Corps.
React, React Native, Node, GraphQL, Kubernetes, PHP, WordPress, Drupal, AWS
I owned design, development, testing, deployment, and maintenance of software and kept delivery on quality, on budget, and on time. I led IoT demos on BeagleBone with GCP and built a strong track record of execution that opened the door to larger leadership roles.
Node.js, Vue.js, D3.js, Python, GCP, Kubernetes, Docker, Tensorflow, AWS
I was part of the Search, Browse and Recommendations team that migrated the search and browse backend from the legacy Java/Scala Oracle ATG platform to a new Node.js stack. I delivered a modern, scalable foundation that empowered the product for millions of users.
Node.js, Express, KrakenJs, Java, Solr, Cassandra, MongoDB
I designed, built, and shipped apps for Android and iOS plus the backend that powered them, growing from junior to leading the banking app, with a direct relationship with the client and a track record of reliable delivery. That experience became my foundation in mobile, Java, and cloud.
Java, Android, iOS, SQL Server, Glassfish, Parse, Google App Engine, AWS
