💻 Featured Engineering Work

🛍️ Composable E-Commerce Microservices Platform
A production-ready e-commerce ecosystem spanning 21+ independently deployable microservices.

Rather than relying purely on theoretical designs, I architected this holistic platform from the ground up to deeply understand modern, production-grade engineering complexities:

  • Resilient Distributed Data: Employs Dapr Pub/Sub coupled with the Transactional Outbox pattern for guaranteed cross-service event delivery.
  • Complex Orchestration: Utilizes Saga patterns for reliable cross-domain Order and Payment rollbacks natively in Go.
  • GitOps Operations: Declarative infrastructure scaling, secrets management, and automated cluster deployment via ArgoCD.
