About
I'm Manuel, a Cloud Solutions Architect at Global Bank Corp in Panama City. I turn business ideas into scalable, maintainable, and cost-efficient technical environments — standardizing cloud patterns across digital products in a regulated financial setting, with AWS, Java/Quarkus, Node.js, and TypeScript.
I hold three AWS certifications — Cloud Practitioner, Developer Associate, and Solutions Architect Associate (2026) — with Solutions Architect Professional in progress. On the side I ship production-grade projects: serverless architecture, a mobile backend on AWS, and AI-powered developer tooling.
Outside of code: I ride a Yamaha R3, shoot motorcycle content with an Insta360 X4, and I'm slowly picking up guitar.
