Hitobito Contributor (2024)

As a contributor to the open-source project Hitobito, I have actively participated in the development of a sophisticated web application designed for managing large-scale organizations with intricate hierarchical structures, such as associations and clubs.

My primary focus has been on implementing a new integration for the Swiss Alpine Club, a significant organization comprising 110 sections and boasting a membership of 174,726 individuals as of 2023. This integration showcases the scalability and robustness of the Hitobito platform in handling complex organizational structures and substantial user bases.

Multilingual Webshop of Swiss Chimney Sweepers (2021-2023)

As the lead developer, I created a bespoke multilingual webshop that seamlessly integrates with the client’s accounting software via a custom Ruby-based connection tool. The shop offers advanced features such as product variants (e.g., different clothing sizes) and accessories. The webshop software was reused from a previous project, where I created a solution from scratch heavily adapted for the swiss market. I also developed the content management system (CMS) to provide a user-friendly interface for managing the webshop’s content and products.

Key features:

• Full synchronization with client’s accounting software
• Support for product variants and accessories
• Multilingual interface
• Heavily customized Bolt CMS with self-made extensions, contenttypes and design for easy content management

CS-Connector (2015-2024)

CS-Connector is a Ruby application to connect ERP Software such as SelectLine to web services. As the creator and lead developer, I strived to help small to medium sized companies to get the most out of their ERP software by avoiding manual data entry between the ERP software and the web service. The software continues to save companies many hours of manual data entry each day.

I created a custom web shop from scratch that is multilingual and fully adapted to the swiss market. It contained a design tool that let users print their design on a small sugar sachet. I collaborated with the printing company in order to automatically create and send suitable PDFs to the printing machine. I also implemented and partially designed the multilingual responsive website of the company using a user friendly CMS.

Service Provider Directory of Association K.

Association K consists of many small service providers. In order to show those to clients of K, I added a service provider directory to the website I created. Employees of K can easily add new service providers to the directory through their accounting software, which is also synchronized with the corresponding web shop. All pages can easily be edited in the CMS through employees of K.

Not shown is a separate application, which lists specialized services providers of K.

The webshop is multilanguage and comes with a website using a single design template, which I implemented from mockups from the designer
