Monthly Shopware Care for stable stores after launch or agency handover.
I’m Hung Mac, a Vietnam-based Fullstack PHP developer focused on Shopware 6 and Symfony. I help small and mid-sized Shopware stores stay stable after launch with monthly health checks, issue triage, update risk notes, and practical technical ownership.
Good fit if you need:
ongoing care for a stable Shopware store, a technical owner after agency handover, or dependable help for checkout, orders, emails, queues, plugins, updates, and small production issues.

Boundaries
Clear scope keeps monthly care predictable.
- Not 24/7 support unless separately agreed.
- Large features, redesigns, migrations, and major rebuilds are scoped separately.
- Production access, backups, staging, and deployment responsibility must be agreed before work.
- Sensitive store or customer data is not sent to AI tools without explicit approval.
AI helps with clarity, not magic.
I use AI carefully to produce clearer reports, summarize logs and release notes, review plugin/update risk, draft practical backlog items, and identify small automation opportunities. You are buying stability, clarity, and Shopware expertise, not AI hype.
Privacy and GDPR matter: sensitive store, order, or customer data is not sent to AI tools without explicit approval.
Who I am
A calm technical owner for stores that already work and need to stay that way.
I’m a Fullstack PHP developer with deep experience in Symfony and Shopware. My background includes Shopware core development, custom plugins, Shopware apps, upgrades, integrations, performance issues, production bugs, and long-term maintenance.
The best fit is a store that is already live, mostly stable, and needs someone technical to keep an eye on the moving parts: checkout, orders, emails, queues, plugins, updates, performance signals, and the backlog after handover.
My Shopware core work is publicly visible in the shopware/shopware repository, including administration workflows, order creation, promotions, media handling, mail templates, documents, storefront behavior, scheduled tasks, SEO, and tracking fixes.
For readers who want extra context: I currently support Aventux as a freelance Technical Lead on Shopware and Symfony work, including architecture decisions, code review, delivery quality, and complex production issues.

AI Workflow
Ecommerce Thinking
Online marketing is not dead, but generic marketing packages are dying
AI is not killing marketing. It is making repetitive, generic, and hard-to-prove work cheaper while making strategy and measurable value more important.

The Internet is still a gold mine, but not in the obvious places
SEO, ads, marketplaces, and content still work, but online businesses need sharper tools, better niches, and faster adaptation.
