• Architected a cross-platform internal chat app (NestJS backend + React Native client) covering system design, API contracts, and database schema end-to-end.
• Implemented End-to-End Encryption (E2EE) via RSA + AES key exchange, ensuring messages are unreadable in transit, at rest, and to the server.
• Built real-time messaging with Socket.IO and RabbitMQ as a message broker, decoupling services to prevent message loss under concurrent load.
• Managed dual-database architecture (PostgreSQL + MongoDB via Prisma ORM) to balance relational consistency with high-throughput message storage.
• Integrated an AI conversational agent into legacy internal systems to automate support workflows and reduce manual intervention.
