Discuss a pluginI also support German Shopware agencies with remote overflow work, debugging, plugin/app development, update projects, and implementation tasks when an in-house team needs extra Shopware capacity.
Discuss agency supportMonthly Care is a fixed retainer for reserved technical attention: regular checks, issue triage, small fixes, update risk notes, and calm follow-up before small problems become expensive.
For stores with broken checkout, failed orders, queue problems, plugin regressions, or production issues that need focused debugging.

The main fixed monthly care setup for small and mid-sized Shopware stores that need regular checks, triage, small fixes, and reliable help after agency handover.
A deeper fixed monthly care retainer for stores with custom plugins, integrations, higher order volume, or more frequent operational changes.
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.
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.
A Shopware 6 Search & Filter plugin that remembers selected category, manufacturer, and property filters for smoother browsing.
A Shopware 6 conversion app for showing recently viewed products in CMS layouts, search, checkout, and customer context.
A free Shopware 6 customer account plugin that cleans up unused guest accounts while keeping associated orders available.
Posts can originate here and queue to LinkedIn, or be imported back as references when API access is available.
A busy Shopware day with staging-to-production go-lives, Shopware 5 to Shopware 6 migrations, careful preparation, and another Shopware 6.7 update.
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.
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.
Share the store version, current situation, and desired timing. I usually reply within one business day with the next sensible step.
Short answers for the questions clients usually ask before starting a technical conversation.
Hung Mac is a Vietnam-based Fullstack PHP developer focused on Shopware 6 and Symfony. He works remotely with German Shopware agencies and merchants. His background includes public Shopware core contributions, custom plugins, Shopware apps, updates, integrations, performance work, debugging, and production support.
It is for small and mid-sized Shopware stores that are already live and mostly stable, especially after launch or agency handover, when the merchant still needs technical ownership without keeping a full agency contract.
Yes. Agency work is a secondary fit: overflow support, debugging, update projects, plugin/app development, and implementation tasks for German Shopware agencies.
Yes. Monthly care is the main offer, but hourly freelance work is possible for scoped Shopware/Symfony tasks, agency overflow, debugging, plugin work, technical reviews, and implementation support.

24/7 support, large features, redesigns, migrations, and major rebuilds are scoped separately. Production access, backups, staging, deployment responsibility, and sensitive data handling are agreed before work starts.
