# Shopware freelancer for merchants and agencies.

> I’m Hung Mac, a former developer on Shopware’s Core team and now an independent senior full-stack developer. I support merchants and agencies with plugins and apps, updates, production debugging, technical reviews, integrations, and ongoing care for existing stores. I currently work remotely from Vietnam and will relocate to Germany in October 2026.

Provider: Hung Mac — Senior Full-Stack Developer and Technical Consultant, former Shopware Core developer, relocating to Germany in October 2026.

## Best for

- Merchants with an existing Shopware 6 store who need dependable technical support
- Shopware agencies looking for experienced overflow capacity for a project or longer engagement
- Teams dealing with difficult checkout, order, email, queue, scheduled-task, or integration issues
- Projects involving custom plugins, apps, updates, or a technical handover

## Deliverables

- A clearly defined scope with priorities, risks, and a realistic next step
- Maintainable implementation aligned with Shopware and Symfony conventions
- Testing of the affected storefront, administration, checkout, or background processes
- Transparent progress communication plus technical handover and deployment notes

## Process

1. Share the Shopware version, task, desired outcome, timeline, and current setup
2. Agree on scope, access, staging, responsibilities, and relevant risks before work starts
3. Implement and test in traceable steps while communicating progress and blockers directly
4. Document the changes, deployment path, and practical next steps for the existing team

## FAQ

### Can I hire you as a Shopware freelancer for a single project?

Yes. I take on clearly scoped audits, debugging, updates, plugin and app development, integrations, and implementation tasks. Before work begins, we agree on the outcome, access, responsibilities, timeline, and acceptance criteria.

### Do you work with Shopware agencies in Germany and Europe?

Yes. I support agency teams with overflow development, difficult production issues, plugin and app work, updates, code reviews, and technical implementation inside their existing delivery process.

### Can you take over an existing Shopware store?

Yes. I normally begin with a technical review covering the Shopware version, custom code, active plugins and apps, integrations, hosting, deployment, backups, and the most important risks before ongoing work starts.

### How does collaboration from Vietnam work?

We agree on shared working windows for discussions and decisions. Some focused work can happen before the European business day begins. Progress, questions, decisions, and risks are documented in writing.

### Which language do you use for communication?

Direct technical communication is in English. German-language project content and written communication are available. Important requirements and acceptance criteria are documented clearly for both sides.

### Do you work hourly or at a fixed price?

Both are possible. Debugging, reviews, and ongoing support are usually handled hourly or within an agreed support framework. A fixed price can be proposed for a clearly defined outcome after a short technical review.

### Can you provide immediate 24/7 support?

No. Availability, response expectations, and production responsibility must be agreed before work begins. For an urgent but contained problem, a focused debugging engagement is often more appropriate than an undefined 24/7 support scope.
