Software reverse engineering

I have a small crypto win exe file (not sure what language it was developed in) and looking for a software engineer to reverse engineer it, provide source code, and identify any malware, backdoors, root kits or crypto wallets that are hardcoded in it and if there are work with me to reverse close the security gaps.

Ideal Skills and Experience:
- Proven experience in software reverse engineering
- Comprehensive knowledge of various programming languages
- Strong knowledge in identifying security vulnerabilities
- Competence in enhancing software performance
- Ability to deliver results with partial information

Deliverables:
- complete source code for exe file provided
- provide overview of functionality (simple 1 page documentation)
- identified risks, malware and hardcoded wallets
- make changes to software per my instructions (only change hardcoded wallet or remove and/or remove all malware)
- test software with me for full functionality
- deliver final source code and new exe
