⚡ What I’m Known For

  • Strangler Fig Migrations: Safely carving up massive 10-year-old monolithic applications (Magento/PHP) and routing them to Golang Microservices with zero-downtime data sync strategies.
  • Platform Reliability Engineering: Designing resilient event-driven systems using Dapr PubSub, Saga patterns, and Transactional Outboxes that do not drop records under heavy loads.
  • GitOps Orchestration: Establishing highly automated, developer-friendly CI/CD pipelines deploying multiple containers to Kubernetes via ArgoCD without manual interventions.

🚀 Core Competencies

  • Backend & Systems: Go (Kratos Framework), PHP (Laravel, Magento 2), Node.js, C/C++
  • Infrastructure & DevOps: Kubernetes (EKS/K3s), Docker, ArgoCD (GitOps), CI/CD pipelines
  • Databases & State: PostgreSQL, MySQL, Redis, Elasticsearch
  • Architecture: Clean Architecture, Domain-Driven Design (DDD), gRPC, REST, Dapr (Pub/Sub & Service Mesh), Saga Transactions

💻 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.
