The goal for this 2-3 months mission was to create a proof of concept (PoC) and deliver a beta version of the mobile application. The project aimed to demonstrate the technical feasibility and core functionalities of the required mobile application. Developed in Kotlin with the integration of sports data from an external API, I specified the essential features, designed the user interface, integrated data via the API, conducted thorough testing, and validated key functionalities before delivering the beta version on time. The results confirmed the viability of the initial idea, and the project is currently in continuous development. I continue to undertake short-term freelance assignments for this client.
