Raj was professional, end-to-end. He reframed my requirements, crystallising communications, and delivered spot-on. Ditto for my change requests. Patient all throughout, bearing with my Pi and BLE newbieness. And highly responsive too. All in all, a delight to work with.

Raj has produced a great beta app (work in progress!), and fully understood a complicated brief. 100% fluent English helps with understanding from both sides. Definitely reccommend and will use again.
