At Taaly, I build and maintain a production language-learning platform with TypeScript Firebase Cloud Functions, Firestore workflows, payments, notifications, and AI-assisted learning features.
I deliver backend modules for bookings, sessions, vouchers, user statistics, organization workflows, balances, and payments. I design secure, scalable Firestore data flows using Security Rules, indexes, transactional writes, idempotency handling, Zod validation, webhooks, and real-time services.
I also build React and Next.js dashboards, strengthen delivery through Jest, Firebase Emulator Suite, GitHub Actions, Docker, and multi-environment deployments, and mentor students in React, Node.js, databases, and full-stack project structure.
