Eugene Efremov is a senior Front-End JavaScript developer with 10+ years of experience building high-performance, production-grade web applications across banking, e‑commerce and telecom domains. He combines deep front-end expertise (TypeScript, React, Next.js, performance tuning, WebGL/Three.js) with backend and DevOps skills (Node.js, GraphQL, Docker, CI/CD, Kubernetes), and has led teams and architecture decisions at scale. Eugene has driven migrations to monorepos and microfrontends, introduced FSD practices, and solved real-world performance bottlenecks (including million-row tables and optimized rendering/asset loading). He mentors and hires engineers, runs onboarding and release processes, and has built developer tools like a Chrome DevTools extension used for logging and feature-toggles. An active educator and content creator, he published ~80 video lessons and runs a Telegram channel about development, reflecting a passion for teaching that complements his hands-on engineering. Based in Oregon but originally from Russia, he traces his roots from assembler and Arduino hardware to modern full‑stack JavaScript, giving him an atypical breadth across low-level and high-level systems.
