Starlin Marrero
@starlinmarrero
Full-Stack developer focused on scalable web systems, APIs, and real-time features.
Dominican RepublicWhat I'm looking for
I build secure, reliable backend and full-stack solutions with a strong emphasis on clean APIs and maintainable data access. Currently, I develop and maintain backend APIs with Node.js and NestJS for BANTRAB, using Oracle DB with TypeORM and Jest unit/integration tests to support core banking-related systems.
Previously, I engineered security-critical platforms at OpSec Security, building RESTful APIs, containerizing services with Docker, and deploying to Azure to improve environment consistency and release speed. At Media Revolution, SRL, I architected scalable features across web and mobile, delivered real-time experiences with WebSockets and Socket.io, integrated blockchain initiatives, optimized REST/GraphQL APIs with PostgreSQL for faster queries, and mentored junior developers while improving AWS infrastructure and CI/CD workflows.
