Code that matters

Senior Web3 Frontend Developer with 8 years of commercial experience crafting responsive web platforms, applications, dApps and games. I have 1.5 years of experience leading teams from 2 to 30 people, both remotely and on-site using various Agile frameworks such as LeSS, as well as Kanban, Waterfall, and release management. I also oversaw the full development cycle, from gathering requirements from the product owner to setting up a fully automated release process with extensive test coverage, detailed analytics, CI/CD integration, and applied a T-shape approach to support team members in their tech stacks.
