I worked on the Magento platform inside Adobe (2018–2020, 2.3 release) and have 10+ years building and operating enterprise e-commerce. My specialty is the intersection most developers don't cover: deep Magento/Adobe Commerce engineering plus the infrastructure to run it — Terraform, Docker, CI/CD, multi-cloud — plus complex system integrations.
Most Magento developers stop at code; most DevOps engineers don't understand the application. I do both. That means I can architect a custom module, build the data pipeline behind it, ship it through a CI/CD pipeline, and keep it stable in production — without handing off between three specialists who don't coordinate.

I help businesses launch and debug their global payment and delivery integrations in days, not weeks.
With hands-on experience integrating 20+ payment and delivery channels across Southeast Asia, Middle East, and global markets, I bridge the gap between your platform and the world's most complex payment ecosystems.
**What I Bring to Your Project:**
• **Global Payment Gateways** – Deep, practical knowledge of Adyen, Stripe, and Airwallex. From KYC verification and sandbox testing to production deployment, webhook handling, and chargeback resolution.
• **Southeast Asian Local Payments** – Expert in local payment methods across Thailand (Kbank, PromptPay, TrueMoney), Indonesia (QRIS, Xendit, PayCools), Malaysia (DuitNow, CardBiz), Philippines (QRPh), and Cambodia (KHQR).
• **Delivery Platform Integrations** – Proven ability to seamlessly integrate with Uber Eats, Foodpanda, and Grab, building centralized order aggregation systems that replace fragile native SDKs.
• **Cross-Border & Chinese Payments** – Experienced with Alipay, WeChat Pay, and cross-border settlement logic for Chinese merchants expanding overseas.
**Why Work With Me:**
I don't just read documentation — I've solved the real problems that documentation doesn't cover. The webhook that fails silently. The sandbox parameter that behaves differently in production. The risk control rule that triggers at 3 AM. I've been there, and I know how to fix it fast.
I communicate clearly in written English for all technical discussions. I'm equally comfortable working with global teams or Chinese-speaking founders navigating Southeast Asian markets.
Let's connect and discuss how I can help you launch or fix your payment and delivery integrations.
