frankel.ch is the personal technical blog of veteran Java developer Nicolas Fränkel. The author previously worked on the Apache APISIX team, and most of the blog content comes from the author's first-hand work experience, technical insights, and records of personal side projects. It focuses mainly on technical sharing for backend development and architecture.
The blog covers a very wide range of topics: it includes in-depth discussions of classic issues in the Java ecosystem (such as whether you should use BigDecimal for monetary calculations), analysis of architectural patterns like API gateways and AI gateways, and complete walkthroughs of the author's personal projects. For example, he documented the full process of creating a seasonal time-lapse video from years of photos taken from the same spot, with detailed breakdowns of everything from image alignment to video generation. He has also recently been consistently sharing explorations of AI applications in software engineering. All content is based on the author's real-world practice, so originality is extremely high.
Unlike much of the clickbait-driven technical content online, discussions on this blog don't lean on dogma. Instead, it prioritizes analyzing problems based on real engineering scenarios, which makes it extremely valuable for working developers to reference.
The site is currently directly accessible from networks in China, loads at a normal speed, and all content can be browsed for free without requiring account registration or login. That said, as a personal blog, it lacks a robust category and search system, so finding specific content is not very convenient. The entire site is only available in English, which creates a higher barrier for Chinese readers, and there is no official support for answering questions about the content.
This blog is great for Java backend developers, API architecture practitioners, and AI engineering enthusiasts with a solid foundation in English, especially anyone who wants to access first-hand practical experience from a working developer.
