Senior🎓
Top SchoolAlberto Brealey-guzman is a Senior Frontend Developer based in London with a 25-year track record building enterprise and consumer web applications, and 13 years of focused professional experience in financial services and trading platforms. He has driven front-end architecture, design systems and reusable SDKs at firms like LSEG, UBS and RBS, enabling rapid onboarding of teams and production-grade cloud-native UIs for P&L and risk tooling. Comfortable across legacy migrations and modern stacks, he has migrated Adobe Flex platforms to JavaScript/AWS, optimised performance at scale, and created testing and state-management tooling used by QA and developer teams. Beyond fintech, he studies climate action and is committed to decarbonisation at the intersection of clean energy, smart grids and climate justice—bringing that systems-thinking into product decisions. Known for pragmatic problem solving, Alberto also quietly maintains engineering craftwork (his GitHub bio: "mostly idle 🐝") while mentoring teams to ship robust, reusable front-end solutions.
