The Letter app is an app for iPhone and iPad to write classic letters. Even today, various things have to be done with classic letters. With this app, you can focus on the content and don't have to worry about formatting. Templates for standard letters, such as the cancellation of subscriptions or insurance policies, make your life even easier.

David Übelacker

The company Übelacker Solutions was founded by me, David Übelacker, to work as freelancer in Switzerland.

I'm a full-stack developer and software architect with 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.

Now, I look back on 20 years of experience in web-based application development. I started with PHP and then worked my way through Java-based development from servlets to JSP and Java Server Faces to Spring Boot and Angular.js. During this time I learned a lot about good web design and excellent user experience, which I can now rely on every day.

For the last 6 years, I've been working for a large Swiss industrial company as technical lead for the implementation of the digitalization strategy with several IIoT services where I gained a lot of experience with React, React Native, Ruby on Rails, Node.js, DevOps and cloud based solutions.

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.
