I've led frontend delivery for Shain's e-commerce product, where I migrated state management from SWR and Zustand to Effector, reducing state-related bugs by approximately 30% and feature development time by around 25%.
I assembled and led a team of five frontend engineers, introduced Feature-Sliced Design, and built a Storybook-documented UI kit to improve onboarding, code quality, and design-to-development handoffs.
At GetMobi, I designed a fintech application with gamification, finance tracking, and an LLM-powered financial assistant. The leaderboard and daily rewards increased average session frequency by approximately 20%, while natural-language expense tracking reduced manual-entry friction.
Earlier at Toptal, I modernized a legacy JavaScript codebase with TypeScript and Effector, built defect tracking and interactive inspection maps, and delivered workforce calendars that cut manual reporting time by approximately 40%.
