The Challenge
Kalasar had a Svelte-based widget that needed to be migrated to React within a monorepo architecture, plus new AI-powered features, a payment system, analytics tooling, and rapid iteration across multiple product areas.
The Solution
Led the full Svelte-to-React widget migration with monorepo setup, component mapping, and API compatibility planning. Built Widget 2.0 from Figma designs to production React code. Implemented Stripe Connect for coach-to-member payments, an emailing system, a real-time voice tour using the Real Time API, UI components, admin tools, and backend features. Built the frontend architecture and landing page from a greenfield repository, an analytics dashboard with PDF export, a review system with free introductory session support, and handled backend optimization and deployment migration.
