Looking for a shared apartment

I am Tawkir Ahmed Fakir, Age 27, Male from Bangladesh. I will be starting my Masters in TUM Garching campus this summer. I am looking for shared accommodation in Garching or nearby areas.
Being a student, I will mostly be spending time with studies, exploring Munich and finding the best beer garden there is. Besides, I like to read a lot and addicted to science fiction and medieval dark fantasy genres. I am also super excited to learn more about the German language and culture. Lastly, if you are interested to learn programming I can help you learn a thing or two.
I am on a tight budget and looking for something within 450 euros. I understand managing accommodation is hard and every bit of help counts! Please send me a message if you have any leads for me.
