Engineering Philosophy

architecture

Clean Architecture

Separation of concerns, dependency inversion, and modular design to build maintainable, decoupled NestJS systems with clear domain boundaries.

labs

Test-Driven Development

Rigorous TDD with Jest & Supertest ensuring 85%+ code coverage, behavioral verification, and reliable CI/CD deployment pipelines.

security

Security-by-Design

Implementing zero-trust RBAC models, JWT authentication, and proactive security hardening throughout every layer of the stack.
