Rockstar🎓
Top SchoolJoão De Souza is a software engineer with five years of experience building full-stack web and release automation tooling, currently based in Montevideo, Uruguay. He moved from front-end and full-stack roles into developer-focused infrastructure work, most recently improving CI/CD and release pipelines as a Release Automation Engineer at Parity Technologies. At Parity he automated benchmark PR creation, optimized crate publishing and parallelized builds for the Polkadot SDK, demonstrating a knack for squeezing performance out of build systems and CI runners. His background includes internal tools development and several early full-stack and mobile projects, giving him a practical end-to-end perspective on developer workflows. Comfortable scripting and configuring complex pipelines, he blends hands-on coding with operational thinking to make developer life smoother. He often operates where developer experience, automation and distributed build performance intersect — a quieter but high-impact part of shipping reliable software.
