Experience

Offline-first Drone Flight Planning App

An iOS application designed for drone pilots to plan and document flights safely and efficiently. The app combines location-based planning, weather data, airspace restrictions, and structured checklists into a single pre-flight workflow.

Built with an offline-first approach, it remains fully usable in remote areas with limited connectivity, a critical requirement for real-world flight operations. The experience was optimized for both iPhone and iPad, with iPad-specific layouts to support larger-screen workflows used in professional and field environments.

Social Network App for Sports Communities

A mobile marketplace connecting youth athletes with professional coaches through personalized video analysis, real-time chat, and paid coaching services.

Athletes could submit gameplay videos and receive professional feedback through annotated video breakdowns, voice commentary, and in-app messaging. Payments, subscriptions, and media sharing were fully integrated into a streamlined iOS experience.

White-label Soccer Team Apps

A suite of 4 iOS applications built for professional soccer teams, all powered by a shared, reusable codebase with team-specific customization. The platform was designed to support the rapid deployment of new team apps while allowing features and improvements to be rolled out consistently across all existing apps.

Each app delivers a complete fan experience, including news and video content, detailed match centers, live scores, standings, and player profiles. Live match updates and commentary ensure fans stay engaged in real time, while the modular architecture enables efficient maintenance and long-term scalability.

Motorsports Fan Engagement & Livestream

A fan engagement app designed to enhance the live motorsports experience through real-time event data, interactive features, and high-quality live streaming.

The app supported multiple simultaneous live streams, driver profiles, competition brackets, real-time event updates, and interactive fan features. It significantly increased daily app usage during live events compared to the previous generation app.
