Monthly Shopware Care for stable stores after launch or agency handover.
I’m Hung Mac, a Fullstack PHP developer focused on Shopware 6 and Symfony. I work remotely from Vietnam with German Shopware agencies and merchants, helping small and mid-sized 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 remote help for checkout, orders, emails, queues, plugins, updates, and small production issues.

Boundaries
Clear scope keeps monthly care predictable.
- Monthly Care is not a simple hourly block. It reserves recurring technical attention for keeping the shop stable.
- Included capacity is used for checks, triage, small fixes, reporting, and follow-up within the agreed care scope.
- Unused time does not roll over unless separately agreed.
- 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, including public Shopware core contributions and certified Shopware 6 developer credentials. My background covers 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.

Shopware Tips
Debug Notes
My Shopware store is not sending emails. What should I check first?
When Shopware is not sending emails, first check whether all emails fail or only one template. Then review Flow Builder, mailer settings, disabled email delivery, logs, queues, and MailArchive.

Debug Notes
Shopware 6.7.11.1 Administration 500 error: Twig Markup returned and shopware/conflicts fix
If the Shopware Administration fails with a 500 Internal Server Error after upgrading to 6.7.11.1, update to 6.7.12.x when possible. Otherwise add shopware/conflicts and rerun Composer.
Need Shopware maintenance or custom plugin development?
Send your Shopware version, current agency/developer situation, known risks, and the support you need. I will suggest the smallest care setup or scoped implementation path that makes sense.
