Top SchoolAlexander Flenniken is a Senior Full Stack Engineer based in New York City with nine years of experience building scalable web applications and design systems. He has shipped production software across agencies, startups, and ad-fraud detection at HUMAN, where he led a transition to React/GraphQL and helped grow a component library to 90+ pieces. At Bocoup he contributed to W3C accessibility efforts and rebuilt the ARIA documentation site, driving a 10x traffic increase after launch. Comfortable across React, Node, GraphQL, PostgreSQL, MongoDB and D3, he pairs front-end polish with robust back-end services and microservices thinking.
