Dear Hiring Manager,
I'm professional electrical engineer with high expertise in arduino etc. I charge high and maintain very good quality of the work, but I want to know what's your definition of the low budget and I'll see it suits the critical value I can afford. However, I deliver on time once the timeline is decided and as long as the payments are made on-time. Moreover, I take 20% advance payment to start the work.
Regards.
Faraz Ahmad
