This saves time and prevents misunderstandings. ### Flexible Engagement (Direct or via Agencies/Teams) I work directly with end clients - and just as well as senior reinforcement embedded in existing teams and agencies, white-label under your brand. You keep the client relationship; I deliver code and architecture. No end-client poaching, no agency overhead on your side. ### Dual-Stack & Architecture At home in PHP/Symfony and Java/Spring Boot, with Vue.js/React/TypeScript frontends. From architecture decisions and API/middleware integration to rollout - end to end. ### Team & Leadership Experience Led up to 20 developers at 1&1 (staffing, onboarding, steering) and founded/ran my own digital agency as managing director. I slot into your processes and tooling (Git, CI/CD, JIRA/Confluence). ### Agency Background I come from the agency world and have seen a lot. This means: fast delivery without compromising quality. And I understand that your project needs to keep running after launch. ### Modern Development & AI Tools I use AI tools daily and productively: Claude Code for AI-assisted development, n8n for workflow automation with AI agents, and Ollama for self-hosted language models. This means faster implementation, consistent code quality, and privacy-compliant AI solutions without cloud dependency. ### No Surprises Transparent communication, clear scope, predictable costs. --- ## Service Portfolio ### 1.
