Freelancer profile translated to English.
Back to original languageAbout Alois
Independent implementation from a single source: from architecture to development to operation, I take responsibility as a sparring partner who actively drives projects forward. Backend-focused, with over 20 years of IT experience and 15+ years of professional web development, including ten years at a Berlin digital agency.
Focus: Headless CMS platforms (Payload CMS, Contentful). My core stack includes Next.js, TypeScript, Tailwind CSS, Payload, and Contentful — not dogma, but a proven foundation that I recommend when it fits the project. Preferably low-ops and serverless infrastructure (Vercel, Northflank), but also other hosting models if needed. I quickly get up to speed with new codebases in this ecosystem. My goal: solutions as simple as possible, as powerful as necessary.
From ten years of agency experience, including: RAG extension of an enterprise AI chat platform with SharePoint and Confluence integration; solo-built Payload CMS platforms for publishing and e-commerce coaching; multi-channel headless platform for a Bundesliga club (Neos Gold Award 2022). In addition to development, I was responsible for technical concepts, contributed to roadmaps, and mentored an apprentice.
My background combines enterprise IT (EDS/Hewlett-Packard), B.Sc. Media Informatics (HTW Berlin, internship abroad in New York), and many years of agency practice. Contentful Certified Professional, IHK instructor qualification.
Remote from Berlin — also available on-site for meetings and coordination.
