Top SchoolPaulo De Castro is an embedded software engineer with seven years of professional experience and a longer track record spanning embedded firmware, cloud services, and startup leadership. He has shipped production IoT and CLI tooling at balena—taking ownership of an npm package used indirectly by millions of projects—and led significant migrations to TypeScript, CI/CD and test-driven practices. His background ranges from low-level C firmware and power-optimised wireless MCU work to building scalable Python real-time bidding services and architecting AWS-hosted web platforms as a CTO who helped raise over £1M. Comfortable mentoring teams and reviewing large volumes of OSS contributions, he blends hands-on coding with customer-facing support and developer experience improvements. Based in Greater Leeds, Paulo pairs academic rigour (MSc, research roles at Cambridge and Unicamp) with pragmatic product delivery across hardware and cloud.
