Freelancer profile translated to English.

Description

Software developer and agency founder from Düsseldorf with 6 years of development experience. I build websites, web apps, and AI features for businesses – from initial consultation to ongoing support, all in one place.

What I build for clients:

- Business Websites: fast, hand-coded sites on modern infrastructure (Cloudflare Pages, GitHub Actions CI/CD) instead of bloated builders

- E-Commerce: Shopify theme development and customization including custom product features, checkout logic, and multilingual SEO

- Web Applications: Full-stack apps with React/TypeScript and Node.js – including an internal helpdesk platform with an AI support bot based on the Claude API

- AI Integration: LLM features, multi-agent pipelines, and automation workflows; my own agency runs on a self-built AI system

- SEO: technical SEO, local SEO, schema markup, and Google Ads for clients in the German market

Why clients work with me:

- I run a business myself and think in terms of revenue and results, not just code

- I verify with data and primary sources instead of guessing

- Native-level German and English, business-fluent Japanese and Chinese – I have professionally localized e-commerce content for the Japanese market (Rakuten)

- Clear communication, punctual delivery, and I stand by what I build

Tech: JavaScript/TypeScript, React, Node.js, Python, HTML/CSS, Shopify/Liquid, SQL, Claude & OpenAI APIs, Figma, Git/GitHub Actions, Cloudflare
