My work centres on four connected areas: system integration and middleware, automation and AI, backend and full-stack development, and e-commerce platforms. Shopware remains available as a specialist capability and a verifiable depth signal.
I design and build reliable integrations between commerce platforms, ERP, CRM, PIM, payment, logistics, marketplaces, and internal tools. The goal is not merely to connect two APIs, but to make data flow traceable, recoverable, and maintainable in daily operations.
View serviceI automate repetitive processes and integrate AI where it creates measurable value: classification, extraction, summarisation, assisted decisions, content operations, support tooling, and developer workflows. Every solution is designed around data boundaries, human review, cost, and failure handling.
View serviceI build and improve backend services, APIs, internal tools, and web applications with a focus on maintainable architecture, clear domain logic, and safe delivery. I can own a scoped product slice or work alongside an existing engineering team.
View serviceI 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.
View serviceI’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.
View serviceI develop and review maintainable Shopware 6 solutions across plugins, apps, Store API and Admin API integrations, storefront behavior, checkout rules, administration extensions, migrations, and production fixes.
View serviceA focused technical review of your Shopware 6 store, custom plugins, theme overrides, checkout flow, logs, queues, indexing, integrations, and update risks.
View serviceI plan and execute the update to the latest stable Shopware 6.7 patch available for your project. Before production, I review server and Composer requirements, custom plugins, apps, themes, integrations, checkout, the online revocation flow, scheduled tasks, queues, and rollback options.
View serviceI investigate broken checkout flows, plugin conflicts, admin errors, failed jobs, payment and shipping issues, API problems, and regressions after updates.
View serviceFor stores that need steady technical ownership, I can review the current state, take over ongoing maintenance, handle updates, fix bugs, and keep a practical backlog for future work.
View serviceI help turn slow Shopware 6 stores into a clear technical backlog by measuring storefront speed, checkout behavior, cache usage, indexing, database queries, plugin overhead, media weight, and third-party scripts.
View serviceI build Shopware 6 plugins and apps for storefront behavior, admin workflows, integrations, checkout rules, data flows, and agency-delivered ecommerce projects.
View serviceI help Shopware merchants who need a technical owner for their server and hosting, a custom plugin, or code prepared with Codex or Claude Code. I review what has been created, finish or correct it where necessary, test it in the right environment, and support a controlled deployment to production.
