- Built an agentic AI platform that turned fragmented HR and analytics data into instant, high-accuracy answers using RAG, saving 100+ work-hours every month. - Led the frontend architecture for a unified internal platform (1700+ users) enabling company-wide planning, reporting, org structure visualization, and automated process execution (e.g., business trips, education) during rapid company growth. - Significantly improved system integrity (decreasing bug report rate by 3x), performance (e.g., improved Lighthouse score from ~40 to 90+, reduced network latency by 40%) and feature delivery speed (up to 4x on similar tasks) by automatic code generation, network layer improvements, full typescript coverage, vertical slice architecture, monitoring, and CI/CD infrastructure.

Led the engineering of the internal Design System (UI Kit). Engineered 40+ strictly typed components in tight collaboration with designers, documented fully in Storybook and ranging from core primitives to complex components used across the entire platform. - Enhanced main data visualization functionality by boosting the performance, browser compatibility, and capabilities of a schema-driven UI generator. - Led the complete migration from Flow to TypeScript. Achieved zero roadmap disruption during an 8-month transition using custom codemods and a hybrid adoption strategy. -Designed unified infrastructure for 30+ frontend repositories via shared npm modules, standardizing local development, quality, and CI/CD. Stack: Git, NodeJS, GitLab, Docker, Kubernetes, Sentry, Webpack, Rollup, Semantic Release - Implemented performance optimizations. Reduced the overall render time in multiple modules and components by up to 7x. - Mentored developers and initiated internal technical workshops. Led knowledge-sharing sessions (advanced topics, architectural patterns) while guiding junior colleagues in their technical growth and daily engineering tasks.
