Frontend Developer at Domclick
Moscow, Moscow, Russia
Summary
👤
SeniorDenis Ostapenko is a Frontend Developer with over five years focused on the React ecosystem and eleven years in software, known for launching MVPs and shipping complex modules from scratch. He combines hands-on implementation (React, TypeScript, Redux Toolkit, TanStack Query) with feature leadership: mentoring hires, establishing frontend infrastructure, and optimizing SDLC processes to remove bottlenecks. At Domclick he delivered a cross-platform calendar MVP, automated partner onboarding with an AI-assisted risk module, and refactored legacy features to cut code volume and speed delivery. At Labirint he improved Lighthouse scores dramatically, migrated core logic to TypeScript and Redux Toolkit, and helped create a unified UI library validated across the holding. He prefers pragmatic engineering trade-offs—forking and adapting UI libraries and moving assets to CDNs to gain autonomy and faster design delivery. Active in the frontend community and a regular conference attendee, he experiments with emerging methodologies and brings those learnings into production.
