Cover image for I developed a mobile application
I developed a mobile application for configuring, calibrating, and monitoring the hardware of an agricultural drone. The application allows operators to configure flight parameters, review device information, perform calibration procedures, and access manual controls. It also uses Bluetooth communication to exchange data with the drone’s hardware in real time. The project was developed using Kotlin and XML, with a strong focus on a clear user experience, reliable device communication, and ease of use during field operations. Main technologies: • Kotlin • Android SDK • XML • Bluetooth • Hardware integration • Real-time monitoring and configuration This was a particularly interesting challenge because it combined mobile development, wireless communication, and physical hardware integration within a real-world agricultural environment.

Cover image for Verbloom is a cross-platform educational
Verbloom is a cross-platform educational platform designed to complement English language instruction both inside and outside the classroom. Its primary purpose is to connect students’ daily practice with teachers’ academic monitoring. Students can develop their skills in verbs, grammar, writing, listening comprehension, and pronunciation through personalized learning paths, interactive exercises, mini-games, spaced repetition, and automatic mistake review. Teachers can manage their classrooms using class codes, create assignments, monitor individual student progress, identify inactive students or those experiencing difficulties, and handle password recovery requests. The academy has access to a SuperAdmin dashboard for managing teachers, students, classrooms, and educational content from a single system. All content, progress, and learning activity are synchronized through a centralized API and securely stored in MongoDB. Verbloom is available as an application for iOS, Android, and the web, and it also includes a separate administrative platform for teachers and educational institutions.
