Hi,
I have read your job post, I'm very interested to work on your project.
I'm a Computer Science student, so I learnt how to do various tasks using computer. I have also learnt how to use C++ and Java, so it would not be a big problem do write a program using C++ and Java.
Please don't hesitate to contact me back and provide any additional details for further discussion. I'm also available on Email and Whatsapp. I'm looking forwards to collaborate with you in this project.
Thank you,
Wui Kian
