Hi @bludnic! 👋

I've been following the OpenTrader project and I'm really impressed with the work being done here. I noticed you're following me (thank you!) and I'd love to contribute to this amazing project.

I have experience with both React Final Form and TanStack Form, and I'd be very interested in taking on this migration task if you're open to it. I've worked with form libraries extensively and understand the nuances of migrating from one form solution to another while maintaining functionality and improving developer experience.

Would you be willing to assign this task to me? I'd be happy to:

• Audit the current React Final Form usage across the codebase
• Create a migration plan that minimizes breaking changes
• Implement the changes incrementally with proper testing

I'm excited about the possibility of contributing to OpenTrader and would appreciate the opportunity to work on this!

Best regards!
