Mobile Skins Escrow Site with Sharetribe

I'm looking for a professional who can develop a game item escrow site using Sharetribe. This platform should primarily facilitate the trading of skins amongst users on mobile platforms. While I'm open to a variety of design options, I currently don't have a specific theme or design in mind, so using Sharetribe templates is also an option.

Skills and Experience:
- Proficiency in Sharetribe
- Mobile/web platform development experience
- Understanding of game item trading systems
- UI/UX design skills
- Ability to create a secure and user-friendly escrow system

Please provide relevant examples from your portfolio.
