Hello am a CS Masters student at Columbia. Have significant experience in C, C++, Java, PHP, SQL, javscript, etc. At a certain point, you understand that learning a new language is not a large undertaking, just a matter of practice.
If there is a need, I am willing and able to start learning this language. I will not put in the up-front work unless it is financially compensated. This is not a language I would learn on my own for fun (I think that goes without saying).
Therefore, if it can be arranged to assign increasingly challenging projects that are substantial and actually needed, I can learn as I go. If interested, send an email to firstname.lastname@example.org. Thanks!
