Dear employer,
Hi
I can convert your Fortran code to C++ and develop a GUI for it. I am completely familiar with both of these languages as I had used them in my masters' thesis. I can help you with your project. Would you please send me the details of the work so that we can talk about it more accurately?
I am a computer programmer with more than 10 years of working experience using Python, C#, VB.Net, C++, MATLAB, FORTRAN, etc.
I can develop your required code with the highest quality and the lowest price.
Believe me one time and you will start hiring me as a long term employee.
Regards,
Abbas
