Generative AI currently dominates discussions, inspiring my decision to integrate ChatGPT into my Letter App (https://letter-app.com). This app enables users to easily compose and print impeccably formatted letters across iPhone, iPad, and Mac devices. By leveraging ChatGPT, I can introduce users to a plethora of supplementary features. These include text correction, enhancement, professional and humorous writing styles, and even the generation of entire letters guided by specific instructions. Read more
In today’s rapidly evolving technological landscape, the integration of Large Language Models (LLMs) into various applications has become increasingly popular. These models, such as GPT-3 and GPT-4 from OpenAI, Turing-NLG from Microsoft, LaMDA from Google, and Llama 2.0 from Meta, possess the remarkable ability to comprehend and generate human-like text. In this article, I will focus on integrating OpenAI’s GPT into Java applications using Spring AI, a upcoming framework designed to simplify the development of AI-powered applications.

When potential users stumble upon your app’s listing, the first impression they get is often through the screenshots you provide. High-quality screenshots can effectively convey the value and functionality of your app, enticing users to explore further and, ideally, hit that “Download” button. Read more
- On January 23, 1996, Java was first released, and over the years, it has undergone significant changes. I started working with Java in the early 2000s, using J2SE 1.3, which lacked features that are now commonplace. Java 5 introduced generics, “for each” loops, annotations, autoboxing, and unboxing, resulting in more modern Java code. Read more

About
I'm a full-stack developer and software architect with over 20 years of experience in web and mobile application development. Passionate about coding, problem solving and modern technologies.
My fascination with computers started early on. When I was 12 years old, I reset my father's computer out of curiosity because I wanted to know what happens when you enter format c:. Only a few years later I created my first own homepage with pure HTML.
Since then, I've worked my way through the full evolution of web development: starting with PHP, then Java-based development from servlets to JSP and JavaServer Faces, on to Spring Boot and Angular. Along the way I learned a lot about good web design and excellent user experience, which I still rely on every day.
I spent six years as technical lead at a large Swiss industrial company, implementing its digitalization strategy with several IIoT services. There I gained extensive experience with React, React Native, Ruby on Rails, Node.js, DevOps and cloud-based solutions.
Today, I work as a senior software developer and technical lead in the Swiss financial sector, building business-critical applications with Java, Spring Boot, Camunda BPM, Angular, Kubernetes and ArgoCD. As an iSAQB-certified software architect, I have a strong focus on AI-augmented engineering: I build solutions with LLMs, AI agents and RAG using LangChain and LangChain4j, maintain open-source developer tooling, and share my experience as a speaker at conferences.
One of my strengths is that I'm very quick to get to grips with new topics and technologies, so I can easily adapt to ongoing projects or kick off new ones from scratch. I believe in building quality from day one. Topics like clean code, secure coding, test-driven development and a good user experience are central to my work.
