Senior🎓
Top SchoolPaulo De Santana is a senior software engineer with 19 years of experience building high-performance systems across Python, C++, JavaScript/TypeScript and Java, with deep roots in GNU/Linux and embedded multiplatform development. He blends scientific rigor from a Physics background with hands-on engineering—from low-level profiling and OpenGL/DirectX game engines to cloud-native AWS/GCP architectures and serverless orchestration. Paulo has led teams and startups (CTO and co-founder roles) to deliver production products, including integrations at scale using Lambda, Step Functions, SNS/SQS, and enterprise ERP connectors. He is an active open-source contributor to projects including CPython, where he helped port core modules for PEP 489 and fixed stability issues, and earlier GNOME work that improved PDF annotations. Based in Santa Catarina, Brazil, he pairs systems-level expertise (ARM/PowerPC/S390x experience) with product-focused delivery and a long-standing interest in astronomy and electronics that informs practical automation and observatory software. Colleagues count on him for performance-driven code, architectural clarity, and a knack for turning scientific problems into deployable solutions.
