Python Dev Needed for Calculation Logic

• Experience with Python/backend development and algorithms
• Experience with data processing and complex calculation logic
• Ability to work on an existing application without breaking current features
• Experience with AI/API integrations is a plus
• Code must be properly documented

Note: An NDA will be required before sharing codebase or project details, as this involves proprietary business logic. Access will be limited to the relevant module/repo only, not the full production system.

Initially, I need 3 new calculation logic tricks to be implemented. I will explain the required input, rules, and expected output with examples.

Important: I have a limited budget, so please share a cost estimate for each trick separately. I prefer starting with one small paid task and continuing further if the results are correct.

Please share your relevant past projects, proposed approach, estimated timeline, and pricing.
