• Developed and enhanced multiple cross-platform applications using Flutter. Utilized various Flutter libraries such as maps for geolocation features, PayPal integration for payment processing, and REST API protocol for data fetching and synchronization with backend services. • Developed and contributed to multiple XR applications using Unity, encompassing a range of projects from small-scale prototypes to large-scale deployments. Focused on various aspects including interactive user interfaces, and immersive environments, fully integrated within IoT ecosystems. Utilized additional tools and plugins to enhance functionality, such as Android Anchors and MRTK for XR experiences, and integrated REST API and MQTT protocols for efficient data transfer. Addressed and overcame challenges related to optimizing performance and ensuring a smooth user experience, while participating from the design of the applications all the way to testing them. • Developed and contributed to several web platforms and CMS tools using Angular, including a small-scale platform for a Horizon project and a large-scale, ongoing project aimed at allowing users to upload multilingual content. Focused on frontend development using Angular, incorporating technologies such as RxJS and HttpClient to handle REST API interactions for fetching and updating backend data. Integrated interactive maps using the Leaflet library, and utilized HTML, CSS, and TypeScript for overall development.• Developed and contributed to a driving simulator for research on driving behavior, utilizing Unreal Engine 4 and Python. Implemented the Carla Simulator plugin to set up a server with various maps, and created client applications using Python and the Pygame library for the test subjects to use, while logging their driving data. Modified maps and environments using Unreal Engine 4, and developed UI elements and gameplay mechanics with Python.

• Developed and contributed to a native Android application using Java for the Play Store, aimed at facilitating volunteering activities. Focused primarily on designing and implementing the user interface, as well as integrating REST API for data fetching and synchronization. The application achieved a decent number of downloads, reflecting its positive reception and utility among users. • Transferred an internal AR project from mobile to AR glasses using Unity and Vuforia. The application was designed to display hardware components in augmented reality for enhanced visualization and interaction. Focused on adapting the application for the new hardware, ensuring compatibility and optimizing performance for AR glasses.
