What I'm looking for

I’m looking for a role where I can build reliable full-stack services and clean REST API’s, collaborate on Cloud and IaC features, and keep improving through research and constant practice.

I’m a Full-Stack Developer with an emphasis on Back-end. I enjoy delivering quality applications through constant practice and research, and I’m motivated by building reliable systems I can maintain and improve.

Recently, I’ve developed healthcare and health system solutions by working with monolith architecture, building scalable APIs with Node.js + TypeScript, Express, and Sequelize, and leveraging PostgreSQL. I’ve also managed cloud infrastructure with GCP and Terraform, implemented asynchronous operations with message queues and event-driven communication using Pub/Sub, and built interactive front-ends with React (Vite) + TypeScript.
