Hi,
I don't think that its a possible thing to do this requirements under native c/c++ environment for such low budget,
I am a full-stack Engineer,
I've BS degree in Computer Science,
I've ISTQB certification in Testing,
i have 6Y+ of experience in:
(Analysis, Web Development, Software Engineering, Software Architect, Quality Assurance, Databases and Linux Administration)
I can deliver better result in this project, but please consider the availability to increase your project budget.
Looking forward to do business with you,
Thank you
