Summary
👤
Senior🎓
Top SchoolLeonardo Vinsen is a Senior Full Stack Engineer with nine years of hands-on experience building product-focused systems across mobile and web using Flutter/React/Angular, Node.js/Go, MongoDB/SQL, and GCP/AWS. He thrives in early-stage startups (including YC-backed Dropezy and multiple Series A companies), where he wears many hats to move fast while keeping engineering quality high. He pairs close stakeholder collaboration with pragmatic architecture decisions—recently leading a Node-to-Go migration that improved throughput and introduced OpenAPI codegen to streamline frontend-backend workflows. His delivery track record includes performance optimizations (test sharding, CI caching), payments and bookkeeping design, and reducing operational costs like logging spend. Based in Jakarta and trained in Information and Computing Science, he brings a mix of product sensitivity, low-level engineering rigor, and a bias for shipping impactful, maintainable systems.
