My Shopware Core work across administration, orders, media, mail, documents, storefront behaviour, scheduled tasks, SEO, tracking, and platform stability is public evidence of depth in a complex production platform.
View contribution proofI 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 capabilityI 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 capabilityI 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 capabilityI 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 capabilityI can own a defined workstream or join an existing product or agency team for integration work, backend delivery, technical review, production debugging, and complex e-commerce implementation. Collaboration is remote until my relocation to Germany in October 2026.
Discuss collaborationShopware is no longer the boundary of my positioning, but it remains a specialist strength. These focused care and debugging options are available for existing Shopware stores that need experienced technical ownership.
For stores with broken checkout, failed orders, queue problems, plugin regressions, or production issues that need focused debugging.
A lightweight fixed monthly care retainer for small live stores that need regular technical eyes without a full agency contract.
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 combine APIs, deterministic rules, automation, and AI-assisted steps to reduce repetitive work and create useful internal capabilities. Solutions are designed around measurable outcomes, failure handling, cost, and maintainability.
Privacy and GDPR are part of the architecture: sensitive business or customer data is not sent to AI services without an explicitly agreed processing model.
I’m a senior full-stack developer with more than ten years of software experience. My core background is PHP and Symfony, expanded through APIs, databases, frontend work, cloud and production operations, automation, and AI-assisted development.
I work best on systems with real business complexity: several platforms need to exchange data, operational work is still manual, a backend carries important domain rules, or a commerce flow has to remain reliable under change.
Shopware is strong evidence of that depth. I worked as a developer on Shopware’s Core team, have public Core contributions, more than six years of platform experience, and four Shopware 6 certifications. I keep this expertise visible without limiting my work to one ecosystem.
I currently work remotely from Vietnam and will relocate to Germany in October 2026. I am available for suitable projects with companies, product teams, and agencies in Germany and across Europe.
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 Shopware 6.7.13.1 update uncovered an AI-assisted search plugin query and a missing production database safety limit.
A practical comparison of four German Shopware hosting specialists, including real strengths, limitations, pricing, support, and the type of store each provider fits best.
Shopify wins on speed and operational simplicity. Shopware becomes compelling when B2B, multiple markets, custom processes, deep integrations, and control matter over the next three to five years.
Share the business goal, current systems, technical context, 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.

Projects involving integrations and middleware, workflow automation, responsible AI features, backend systems, internal tools, complex business logic, and e-commerce platforms are a strong fit.
Yes. I can deliver a defined project directly for a company or join an existing product or agency team for a scoped workstream, technical review, debugging, or senior implementation support.
Yes. Shopware remains a specialist strength, including integrations, plugins and apps, updates, debugging, performance, and ongoing care. It is part of my experience rather than the limit of my positioning.
I am relocating to Germany in October 2026. Until then I work remotely from Vietnam with agreed collaboration windows for European teams.
