Full-Stack Development

Fullstack developing is exciting in many ways, one of which is that it allows me to build holistic systems from scratch and integrate different technologies. I usually start from first principles and plan the system's structure, recognizing that a well-organized foundation is a precondition for integrating functionality and thoughtful designs. Fullstack developing includes web applications, desktop software, mobile apps or industrial software.

Data Systems and AI

In today's world data has become an integral part of most digital technologies, products and business processes. With data gaining in importance businesses increasingly rely on systems such as artificial intelligence, databases, APIs, ETL-pipelines, big data analysis, model simulation or visualizations. In the past I built prediction algorithms for the finance industry, data integrations for marketing businesses or manufacturing systems, crawling bots, recommendation and classification systems or LLMs.

Industrial Software

Industrial software often involves automating and scaling manufacturing processes and the integration and interoperability of data streams. Industrial software is generally used in manufacturing systems, but today they are built for all kinds of industries, including logistics and transportation, accounting, banking, insurance or marketing. One of the exciting things about it is not only to automate data streams and business processes, but also to make them more intelligent by implementing AI algorithms.

Release Notes

Bitcoin onboarding - release of a comprehensive documentation

ChrisYoon April 17, 2025

Bitcoin is not only a highly fascinating rabbit hole, it is also a huge white pill that gives me hope for our future. In recent years I was frequently asked by friends and clients to help them implement a Bitcoin setup. Before I implemented the setup I tested the entire onboarding process on my own devices and documented the main steps. In doing so, I created a documentation that gives an overview of the main advantages of Bitcoin and discusses different risk scenarios, solutions for key storage and other security considerations.

The fundamental flaws of AI

ChrisYoon March 25, 2025

The invention of large language models (LLMs) has profoundly shaped the landscape of AI, sparking another wave of hype in the media and the industry with voices even speculating about the emergence of general artifical intelligence. What often goes overlooked in these optimistic accounts, however, is the fact that the challenges of AI to engineer general artificial intelligence are more fundamental than commonly assumed.

How engineering principles help me build high-quality software

ChrisYoon January 21, 2025

In recent years software engineers have become sloppy, especially when compared to the rigor and precision of traditional engineering disciplines. And, I think, at least part of the reason is that software engineering has increasingly decoupled from physical constraints. In recent years I came to the conclusion that I could borrow principles from traditional engineering and apply them to software engineering in order to improve the quality of my software products.
