Senior🎓
Top SchoolIsaac De Souza is a versatile Semi Senior Software Engineer based in São Paulo with seven years of experience building and refactoring full-stack systems across PHP, Typescript, Go and Node.js. He specializes in improving developer experience—creating a monorepo with cloud-configured Gitpod, CLI tools and automation that cut onboarding and manual work dramatically. Isaac migrated legacy analytics APIs to serverless AWS Lambdas, built a NestJS microservice to automate Google Analytics/GTM setup, and optimized heavy export jobs to handle millions of records in minutes. He pairs frontend React work with backend integrations (REST/GraphQL, OAuth2, RabbitMQ) and has repeatedly reduced resource usage and manual effort through pragmatic refactors. Recognized internally for consistent top performance and mentoring peers, he also acts as a technical bridge in customer meetings and cross-cultural teams. Ambitious about growth ("Rumo a dev sênior!"), he blends hands-on delivery with developer-first process improvements that scale.
