Cross-Platform Distance Measuring App Development

I'm seeking a skilled app developer for a unique project. The goal is to create an app for both Android and iOS that uses device cameras to measure distances between various items. This could be for applications like determining "closest to the hole" in a golf tournament or measuring from a bullseye on a target.

Key Features:
- Primary focus on measuring distances
- Ability to save only selected measurements

Ideal Skills and Experience:
- Proficient in cross-platform app development
- Experience with camera integration in mobile apps
- Strong understanding of measurement algorithms
- Knowledge of user-friendly interface design
- Ability to implement selective data saving

Please provide your portfolio and examples of similar projects you've completed. Looking forward to your bids.
