Top SchoolGuil Caggia is a Principal Software Engineer based in London with 10 years of experience designing and shipping scalable, service-oriented systems across startups and enterprise teams. He combines hands-on backend architecture (Node.js, TypeScript, GraphQL) and cloud migrations with people leadership — having built greenfield platforms, hired and mentored engineering teams, and steered product pivots at Pynea. His career spans DevOps-heavy roles and high-traffic media and infrastructure companies (The Economist, Vorboss, IAG), where he focused on reliability, observability, and immutable deployment practices. Guil frequently blends domain-driven design, functional patterns and rigorous testing to produce maintainable codebases and has migrated systems between AWS and Google Cloud to align product strategy with operational needs. He brings an entrepreneurial mindset from founding HubEngineer and an IoT startup, pairing pragmatic delivery with technical curiosity rooted in a background in mathematics and teaching. Notably, he drives both hands-on execution and long-term engineering culture, making trade-offs that balance speed, quality and scalability.
