Salesforce Development for Inventory Management

I need a Salesforce expert to create custom objects for inventory management. The project would entail managing inventory items in Salesforce and synching with our SaaS application for the inventory lifecycle management, case management, and subscription billing. The project will entail: - Create / modify 8 Salesforce objects (6 custom, 2 SF objects) - Creating relationships between objects - Create or integrate .csv bulk data uploaders for 2 custom objects - Integrating Salesforce with our SaaS application for data sync via REST API's - Creating automations for synching records between Salesforce and our SaaS application - Implement error handling, retry logic, and failure logging and alerts - Migrate data from our SaaS application into Salesforce. The ideal candidate will have a strong understanding of data management and organizational skills to effectively manage inventory. We prefer a developer with Salesforce Platform II certification. Our budget is to be viewed as a baseline. We may break this project up based on budget availability and may complete various phases over time.
