Top SchoolSergei Demchuk is a Senior Full Stack Engineer with 12 years building scalable web and backend systems, currently focused on Golang and cloud-native architectures. He has shipped microservices, GraphQL and gRPC APIs, and integrations for payments, telephony and video conferencing across products like LMS, TalentTech and OZON, combining strong PostgreSQL and Kafka experience with Kubernetes-based deployments. Comfortable across the stack, he pairs TypeScript/React front-ends with production-grade Go services and CI/CD practices, and has deep operational experience in nginx, DNS, release automation and observability. Beyond enterprise projects he has independently developed varied consumer-facing sites (e‑commerce, dating, forex signals, video) and an Android TV control app, showing a pragmatic full-product mindset from server to UX. Not obvious from titles: he has a military engineering background and a long history of owning boxed product releases, licensing and update mechanisms, reflecting a systems-level approach to reliability and deployment.
