I developed a native Android application in Kotlin Multiplatform (KMP), which optimized the management of security rounds in a corporate environment, implementing a dual role system with important functionalities for real-time tracking and incident reporting.

I designed and implemented a notification system for patrol schedules, integrating native QR scanning with ML Kit Barcode and CameraX for location validation. I developed modules for incident registration linked to QR codes, PDF report generation, and real-time history visualization. I implemented a coroutine for collecting precise device location, optimized for use in security reports.

I worked in a 3-person team for 2 main clients to develop a web system for managing therapeutic services. With key features such as multi-user, role system, and calendar.

I designed, developed, and implemented the page according to the client's functional requirements. I selected and defined the set of frontend technologies for the project, considering the ability to scale and adapt to future requirements. I implemented real-time push notifications to generate automatic reminders. I digitized billing (automatic PDF generation), eliminating physical printing and reducing printing costs by 100%.

I competed in the 'Hack the Future' event. It had 30 participants and lasted 1 day. I developed an Android application that used an API with features such as login, parallel endpoint requests, and craft management. Ultimately achieving 2nd place in the competition.
