Senior🎓
Top SchoolMarco Lopes is a Senior Software Engineer from Rio de Janeiro with five years of hands-on backend experience specializing in Node.js, NestJS and TypeScript. He has designed and delivered resilient, high-throughput financial integrations and reconciliation systems that cut manual processing from weeks to hours and reduced critical query latencies from 21s to 1s. Comfortable across DDD, Clean Architecture and CQRS, he also optimized deployment artifacts (cutting Docker images from ~1GB to <200MB) and introduced observability and zero-downtime refactors in production. He pairs technical leadership—mentoring juniors and owning end-to-end features—with a pragmatic focus on reliability, transactional consistency and anti-fraud integrations. An engineer who started in mechanical engineering, Marco brings a systems-thinking mindset and a demonstrated ability to learn new technologies rapidly and deliver business-impacting solutions.
