Architecting Systems at Scale

I'm a Backend & Platform Engineer with 7+ years of experience designing and stabilizing large-scale SaaS systems — with deep ownership of architecture, data modeling, and production reliability.

Currently at AppSquadz, I lead the complete re-architecture of a legacy CodeIgniter platform into a Distributed Modular Monolith using NestJS. Domain-driven services run independently on AWS EKS while sharing centralized MySQL and Redis, maintaining transactional consistency without the complexity of full microservices.

I own the full stack of platform decisions — API design, database schemas, multi-tenant isolation, and technology choices — while collaborating with DevOps on observability and scalability.
