Looking for developer partner to help refine a sports trading card marketplace MVP

I’ve been building a sports trading card marketplace called MintGemTen. The goal is to create a cleaner, lower-fee platform for buying and selling sports cards.

I already have a partial build going using Supabase that includes:

• user accounts
• card listings
• marketplace browsing
• image uploads
• seller tier system

However, as the project grew I realized parts of the architecture could likely be improved or refactored to scale better.

I’m looking for a developer who might be interested in reviewing the current project and helping refine or rebuild parts of it so it can become a solid production platform.

Ideally this would be someone interested in startups or marketplaces. I’m open to collaboration, long-term partnership, or paid work depending on the fit.

    Hey - we're a software engineering team and MintGemTen caught my eye. We've worked on sports-adjacent products in the US - including ScoreAI, a sports analytics and predictions platform using ML to process sports data in real time - and on marketplace architecture for an EU omnichannel retailer (multi-seller listings, integrations, scalable order flows on AWS).

    The Supabase foundation you have is a solid start but you're right that scaling a marketplace brings real architectural challenges - seller trust systems, image handling at volume, search and filtering as inventory grows, transaction integrity.

    Happy to take a look at what you've built and give you honest feedback on where the architecture holds up and where it might need rethinking. If you wish - please share your email or linkedin and let's continue there

      Thanks for reaching out, I appreciate it. I’d definitely be open to discussing it further. The project is still early and I’ve realized parts of the architecture likely need to be refactored before it becomes a solid MVP.

      If you’re interested, I’d be happy to walk through the current build and what I’m hoping to improve to see if it might be a good fit to collaborate.

      Feel free to reach out on Discord: concrete.goon

    Hey MGT Market Place,

    This sounds like an interesting project and one that I'm sure we can assist with. We've build many custom platforms for start ups.

    It would be great to hear more about this project and the next steps.

      Thanks for reaching out, I appreciate it.

      The project is a sports trading card marketplace called MintGemTen. I currently have an early build using Supabase with user accounts, card listings, image uploads, and basic marketplace browsing.

      I’m mainly looking for help reviewing the current architecture and refining it into a stable MVP that can be launched publicly.

      If you’ve worked on marketplace or marketplace-style platforms before, I’d be interested to hear about your experience and the tech stack you usually work with.
