Sergey Semenov is a Technical Lead based in Malaga with 13 years of experience building full-stack and blockchain systems, with deep hands-on expertise in Solidity and Web3 as well as Elixir and classic web stacks. He has progressed from PHP/MySQL web development and backend engineering at Readdle to architect and lead roles, recently focusing on DeFi and smart-contract work alongside full-stack responsibilities. Sergey combines systems-level architecture experience with practical implementation—shipping dApps and multiple smart contracts while also running server-side infrastructure in AWS. Comfortable moving between legacy LAMP projects and modern distributed architectures, he brings a pragmatic engineering mindset and a track record of turning prototypes into production services. An interesting thread through his career is frequent role-shifting between backend, architect, and Solidity specialist positions, reflecting adaptability and a broad technical palette.
