Clubers
Mobile loyalty application for a club network spanning restaurants and other venues, where users earn discount percentages based on their consumption across participating locations. Provided support on the original Xamarin app and led the full migration to Flutter as the sole mobile developer. The app includes a home feed of participating venues, an interactive map, and a QR code system for registering consumptions. Also contributed to the ASP.NET backend, with a key contribution being the implementation of in-app payments, and built the React-based admin panel for managing platform data. Firebase and SQL Server used for storage and data management.
CvBuilder
Full-stack web application for creating and showcasing a professional virtual resume. Users can manage their work experience, projects, education, career information, and skills — all presented through a unique public profile with per-module visibility controls. Includes a contact profile feature that allows visitors to reach out directly to the user. Built with Next.js on the frontend, ASP.NET as the backend API, PostgreSQL as the primary database, and Firebase Storage for image handling.
Epod
Native Android application for vehicle transport logistics, built solo with Kotlin, Jetpack Compose, and MVVM architecture, consuming a custom REST API. Designed for a client whose operation involves shipping Mexican-manufactured vehicles to the United States. The app supports multiple user roles across the full transport workflow: drivers inspecting vehicles and logging VIN numbers, damage reports, and photos; border crossing agents verifying documentation; and staff managing cargo pickup and final delivery. Involved in both development and functional definition of the application.
Dr. ISSS
Healthcare mobile application enabling video consultations between doctors and patients, including prescription management, appointment scheduling, medical records, and lab studies — built with Flutter. Contributed to multiple modules across the app, combining hands-on development, technical support, and involvement in project and implementation planning. Also helped build a React-based web platform for medication administration during the project's early stages.
HoS
Mobile application for hotel housekeeping management, built with Flutter and a custom REST API backend. Worked as Tech Lead for the mobile area, gathering requirements directly with the client, defining development strategy, and contributing to hands-on development. The app delivered a fast, fluid experience for hotel staff, with push notifications alerting teams about rooms pending cleaning or status changes.
Sofia EMED
Full-stack medical management system built with ASP.NET, SQL Server, jQuery, and Bootstrap. Led a small team of one developer and one tester, taking over an existing system to build new modules and provide ongoing support. Key contributions included a dynamic consultation system adaptable to any medical specialty, doctor schedule notifications, and fully customizable prescription templates per doctor — enabling the system to be marketed to physicians across any specialty.
Clicfans
