Kelsus

Kelsus was hired by a cloud services company to help with API development for vendor integration. As an extension of the company's technology team, Kelsus attended vendor meetings, learned about their business models, and implemented their APIs using a JavaScript framework. The team was responsible for writing the code, testing, and documenting the process for each vendor. The partnership, which began in January 2020, is ongoing. The client chose Kelsus for their strong agile culture and trusted their ability to deliver based on the company's reputation and past performance.

For WazooApps Inc., a social network for pet owners, Kelsus was tasked with building and managing the mobile app. Starting from defining the product and goals, Kelsus helped refine the main features and handed it over to their engineering team for development. The app was launched in early 2018, and since then, Kelsus has been responsible for app maintenance, updates, and feature refinement. The team used a combination of JavaScript, Objective-C, React Native, Swift, and JavaScript for Android. The engagement started in January 2017 and continues to this day, with the client investing around $3.5 million in the project.

CityPASS, a hospitality and leisure company, engaged Kelsus for IT staff augmentation. The team was brought in to enhance an existing system to streamline price record handling for a major customer. Kelsus implemented a sophisticated workflow that included API communication between different systems and UX changes. The project ran from December 2024 to February 2025 and was successful, leading to Kelsus being retained for additional software development work. The client appreciated Kelsus's culture and flexibility, which aligned well with their own.
