Designing modular, maintainable, and high-throughput backend services using NestJS, TypeScript, PostgreSQL, and Redis.
NestJS brings Angular-style enterprise architecture, dependency injection, and strict type-safety to Node.js backend development.
I specialize in architecting modular NestJS backends that scale cleanly as engineering teams grow, avoiding the spaghetti code common in unstructured Express apps.
From microservices with RabbitMQ/Redis to robust REST APIs documented with Swagger and validated with Class-Validator, I build rock-solid server architectures.

JWT access/refresh tokens, role-based access control (RBAC), and custom guards for API security.
