Pham Hoa (Joe) — Magento 2 / Adobe Commerce Engineer & Team Lead

LinkedIn Email Adobe Certified Expert Ho Chi Minh City, UTC+7 Open to new roles and Magento projects

I build and run Magento 2 / Adobe Commerce stores that sell in five markets, and I lead the team that ships them. 5+ years in software: checkout speed, ERP and accounting integrations, tracking that the marketing team can trust, and a release process where nothing deploys until the tests pass. These days I also put AI coding agents to work, inside the same test gates.

Problem What I did
Checkout performance
US fireplace retailer · Magento 2.4.6		 Cut checkout time by 70% from cart to payment and the checkout step itself by over 80%, slashed brand-page response time by over 70% with a query rework, and lifted mobile PageSpeed to 90. Led the 3–4 developer team: onboarding, reviews, every production release.
Accounting & inventory integration
Canadian B2B distributor · QuickBooks Desktop		 Rebuilt the QuickBooks Desktop integration end to end: customers, orders, invoices and stock reach accounting on their own, backed by a full automated test suite.
B2B storefront redesign
Same distributor · Hyvä		 Took the redesign from concept to a custom Hyvä storefront, with USD and CAD pricing, Canadian tax and ShipStation shipping.
Omnichannel ERP sync
Vietnamese fashion retailer · Odoo		 Connected online and retail stores to the Odoo ERP, so products, stock and orders stay in sync across every channel.
Analytics you can trust
Fast-food chain, Vietnam · GA4 + Meta		 Made sales data accurate: every purchase tracked exactly once in Google Analytics and Meta, from browser and server, with missing details filled in. Also added MoMo payments.
Platform upgrade
Steel & building materials group · Magento 2.4.8		 Brought the store up to Magento 2.4.8 and PHP 8.4, upgrading about 20 add-ons inherited from a previous vendor.
Extended warranties
Global camera brand · US & Canada eStore · Adobe Commerce Cloud		 Built the flow that sells extended warranties, including warranty-only purchases, and closed security-scan findings on the eStore.

Project What it is
aic2026-video-retrieval The backend I owned in our team's AI Challenge HCMC 2026 entry: describe a scene in plain words, and it finds the moment in hundreds of hours of video. Contract-checked across repos, 538 tests behind a CI gate. Python · NumPy · SigLIP-2 / CLIP · OCR · ASR · SQLite FTS5
chatkeep-zalo Chrome extension, on the Chrome Web Store: export your own Zalo chats with photos and media, resumable, nothing leaves the computer. JavaScript · Manifest V3 · IndexedDB
chatkeep-messenger The same idea for Messenger on facebook.com, plus a module that turns a group's posts and comments into a digest. JavaScript · Manifest V3 · IndexedDB
Private side projects (happy to demo)
  • Store audit pipeline: finds slow US and EU online stores and writes each a one-page speed and tracking audit; 28,000+ stores screened. Node.js · BigQuery · PageSpeed Insights API · pm2
  • myIelts: a browser-only IELTS computer-test simulator with timed exams, answer review and an AI-tutor report, covered by end-to-end tests. React · TypeScript · Vite · Vitest · Playwright
  • PODSpark: a test-gated harness in which an AI coding agent built a print-on-demand planning tool overnight, unattended, finishing 100% of its planned tasks. Next.js · PostgreSQL + pgvector · Drizzle
  • buildloop: a command-line tool that keeps AI coding agents honest: a task counts as done only when its tests pass.

How I work

  • Measure first. Before and after on the same environment, so the numbers settle the argument.
  • Gates over promises. CI that blocks the deploy until the tests pass, for people and for AI agents alike.
  • Leave a trail. Decision records and handoff notes, so the next engineer starts warm.
  • Speak business. A merchant should understand what changed and why it pays off.
