Laravel developer – improvements and optimization on a management & inventory system

Description: I have a working Laravel web system (Livewire + MySQL) and need improvements and optimizations across several modules. The work would be done in stages, module by module:

1. Inventory / code sales: show the amount with its unit (usd / diamonds / uc), order products by value, show out-of-stock products, add cost per code, show cost and profit in the history, and improve the excel import preview.

2. Digital cards / recharges: real profit and margin calculation in bolivianos, and a balance reconciliation screen.

3. Streaming: account-level cost control (with renewal and expiration), profit reports by store and platform, history cleanup and performance optimization.

4. Wallet: history and logging improvements.

Looking for a developer experienced in Laravel and business logic, organized and with good communication. Please send your proposal with your experience, estimated timeline and budget.
