Dennis

Hello world 👋🏻

I'm Dennis, a full stack developer from Germany with over 10 years of experience in building, breaking, and rebuilding web systems.

I started my coding journey with VBA, moved through Java, C#, and Go, and finally found my flow in Python, HTML, and JavaScript the perfect mix for automation and web scraping.

Over the years, I’ve built crawlers of all kinds: from lightweight data collectors to complex distributed scrapers for e-commerce, analytics, and content aggregation. Now, I’m sharing that expertise so others can use it too.

💻 Tech stack: Python, Node.js, Go, C#, HTML/CSS, JavaScript, SQL, REST APIs, Puppeteer, Playwright, Scrapy
⚙️ Focus areas: Crawling architecture, API integrations, automation pipelines, data normalization
🌍 From: Germany
