I need an experienced developer to:
Fix the critical security issues identified in the audit
Complete and correct key financial features (deposits, withdrawals, balances)

Deploy the platform on Vercel
Connect my domain
Configure my own API keys (Twelve Data, email, etc.)
Import the existing database if provided
Perform full testing (login, trading, charts, admin, deposits, withdrawals)
I will provide the full audit report and source code to the selected developer.
