To be very honest, we are a startup but before coming to this freelancer portal we had worked on some projects:
1) Course allocation system for IIT G
2) Exam portal for conducting exam
3) Server health monitor system
4) Internet of things based app( an app which talks to phone, television, air conditioner and more)
even we would love to share that we mostly are IIT passed outs just to show we are capable enough to understand your needs and value of your time.
