About

I'm a Software Solutions Architect based in Bangkok, Thailand, with 10+ years of experience across software engineering, enterprise architecture, digital commerce, cloud solutions, and technical leadership.

I turn business requirements into scalable, reliable, and maintainable platforms — owning architecture end to end, from system design and integration strategy through production readiness, performance, and incident resolution. My background as a hands-on backend engineer and team lead keeps my architecture grounded in what teams can actually build and operate.

Area Focus
Architecture Enterprise software architecture, microservices, system integrations, REST and GraphQL APIs
Digital Commerce Adobe Commerce / Magento 2, Shopify and Shopify Plus, enterprise, multi-brand, and multi-country commerce
Cloud AWS cloud architecture, high availability, scalability, and disaster recovery
Performance & Data Performance optimization, database architecture, caching, and background processing
Leadership Technical leadership, architecture reviews, mentoring, and digital transformation

Career Highlights

  • Enterprise fashion retail: led solution architecture for H&M and COS e-commerce environments across Southeast Asia, spanning Adobe Commerce Cloud, Shopify Plus, AWS, PIM, payments, search, and marketplace integrations.
  • Peak-traffic resilience: designed traffic-protection and product-ranking capabilities to keep commerce platforms available during the highest-demand sales events.
  • Multi-tenant scale: architected a custom Magento indexing approach supporting 800 storefronts on a single shared platform for a US-based SaaS client.
  • Modernization: led an enterprise search migration from Elasticsearch to Algolia for a major electronics retailer.
  • Delivery: led a 14-person cross-functional engineering team and used blue/green deployment strategies for zero-downtime production releases.

Shopify Apps & Development

Published apps on the Shopify App Store that I've designed and built, covering store monitoring, image SEO, and automated pricing.

AltStar app icon AltStar  SEO · Accessibility
Finds product images with missing ALT text and generates it in bulk from a store-defined template, with real-time product sync and daily scheduled generation on higher plans.
Flash Sale app icon Flash Sale  Pricing · Bulk Editor
Schedules flash-sale campaigns: prices update through the Shopify Admin API when a sale starts, a public page shows a live countdown, and original prices are restored automatically when it ends. Supports bulk SKU import.
StoreGuard app icon StoreGuard – Store Monitor  Store Monitoring
Monitors product, variant, inventory, price, collection, media, and publishing changes; flags unusual catalog activity as prioritized incidents, with change history, automated scans, and alerts.
