    Shopware 6 Full-Stack Developer

    Blue Design – felgen-schweiz.ch, Switzerland

    Swiss B2C and B2B online shop for wheels and tyres, built on Shopware 6 and available in four languages. Same scope as on enthus.de – custom plugins, storefront theme, integrations and deployment pipeline – with a strong focus on the sales process.

    • Plugin development – 30+ custom plugins built or maintained: B2B pricing and registration, product catalog and tyre finder, redirects and SEO, checkout and order flows.
    • respond.io integration – new customers are synced as contacts and their conversations opened, assigned and tagged automatically, so the sales team picks up every lead right away.
    • AI across the sales cycle – Claude Code for development and the OpenAI / Gemini APIs in the shop itself, optimising the whole sales cycle from automated catalog translation (DE / FR / EN / IT) to lead handling and customer communication.
    • DevOps – zero-downtime atomic deployments with GitHub Actions and PHP Deployer across six environments, nightly production-to-mirror sync with data sanitising.

How I work

Clear requirements, consistent architecture, AI held to the same standards.

Consulting & communication

  • Requirements elicitation & ticket breakdown

    Work directly with clients to uncover the real need behind a request, ask the right questions early and agree on scope, then translate it into clear, estimable tickets with acceptance criteria that the team can pick up without back-and-forth.

  • Team consulting & continuous documentation

    Technical point of contact for the whole development team (architecture decisions, code review, unblocking colleagues, keeping the codebase consistent). Treats continuous reports and analysis documents as the backbone of agile, accurate development and progress tracking, steadily building a rich knowledge base of project history and decisions that powers every future AI-assisted analysis.

AI-assisted development

  • Claude Code as the primary tool

    Strictly organised context for every branch and ticket (isolated sessions and git worktrees), so each session starts with exactly the knowledge the task needs and nothing leaks between tasks.

  • Two-level skillsets, built for multi-project teams

    A generic, company-wide set of skills applied to every project, keeping architecture and conventions coherent across all of them, making each easier to maintain and extend, and shortening the learning curve for newcomers. On top of it, a deeper layer of project-specific skills and CLAUDE.md committed to each repository, shared between developers and continuously upgraded with every change.

  • Architecture & quality standards

    Strict separation of concerns, predefined architectural rules and naming conventions enforced across the entire project, built on solid OOP (SOLID, dependency injection, design patterns) and backed by strong QA; AI-generated code is held to exactly the same standards as hand-written code.
