Build a backend that scales with your business logic, not just your user count. I design modular, multi-tenant SaaS architectures that support diverse industry workflows within a single, maintainable codebase. Utilizing Nx Monorepos and NestJS, I create decoupled services for IAM, Payments (PayPal/Stripe/etc), and real-time communication via WebSockets. My approach includes implementing Redis caching layers to handle high-traffic windows and architecting robust CI/CD pipelines via GitHub Actions or Azure. I focus on creating flexible systems where core logic remains stable even as you add tenant-specific features
