# Solve commerce problems beyond a single platform.

> I support commerce teams with platform architecture, custom business logic, integrations, checkout and order flows, performance, migrations, and production issues. Shopware is my deepest platform experience and a strong technical proof point—not a boundary around the projects I take on.

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

## Best for

- Complex checkout, order, catalogue, customer, or fulfilment workflows
- Commerce integrations and platform extensions
- Platform reviews, migrations, performance, and production debugging
- Shopware projects that benefit from former Core-team experience

## Deliverables

- Technical assessment and prioritised path
- Platform, extension, integration, or custom application work
- Testing across affected customer and operational flows
- Release planning, documentation, and handover

## Process

1. Start with the business flow and platform constraints
2. Trace dependencies across code, extensions, infrastructure, and integrations
3. Deliver the smallest safe change with clear validation
4. Document follow-up work and operational ownership

## FAQ

### Do you still take Shopware projects?

Yes. Shopware remains a specialist strength, including integrations, custom plugins and apps, updates, debugging, performance, and ongoing care. I also take suitable backend, integration, automation, AI, and broader commerce projects.
