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.
Hi,
I came across your post about MintGemTen — it’s great to see you already have an MVP with core marketplace features in place.
I’m a full-stack developer working with JavaScript/TypeScript, React, and Node.js, and I’ve also worked with backend systems and databases (including Supabase/Firebase-style architectures). I’m comfortable reviewing existing codebases, improving structure, and helping prepare projects for production and scaling.
I’m currently looking for paid remote work, and your project sounds like a great fit where I can contribute real value.
I’d be happy to review your current setup and discuss how I can help refine or rebuild parts of it efficiently.
Let me know if you’d like to connect.
I'm a professional software developer and specializing in MVP creation and scale MVP to actual product.
Let's connect and discuss more about your product.
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 - 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
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.
Hey there. I can help. Would be good if you could send me detailed info.
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.
Hey there.
Is there any chance of having direct contact? I sent an invite to concrete.goon(Discord), but nothing happened. Could you ping me max_polinskiy(Discord)
This sounds like an interesting project. I’d be happy to learn more and possibly take a look at the current build.
If you'd like, you can reach me on Discord [glassestoone], or let me know the best way to contact you.
I would be glad to explore the opportunity to work with you. Could you please share your contact number? Alternatively, we can connect via email at [email protected]
I look forward to discussing this further.
