Senior Frontend Engineer → Team Lead Dats.Team
Worked as an independent remote contractor in a full-time engagement, becoming Team Lead for the final two years. Designed and owned a reusable React and TypeScript library with a shared data layer and headless UI components, reducing backend feature integration time by two to three times versus the previous approach.
Built and maintained React and Next.js applications using Redux, REST APIs, WebSockets, Zod, SSR, ISR, the App Router, and React Server Components. Owned semantic versioning and release management within a Lerna monorepo, reduced client bundle size by 20%, and improved Lighthouse LCP and FCP metrics.
Led a frontend team of four to five engineers through planning, prioritization, architecture decisions, code reviews, mentoring, and monthly one-to-one meetings. Expanded automated coverage with Jest, React Testing Library, and Playwright, and introduced Claude Code workflows and reusable AI-assisted development skills.
