I am an electronics engineer, trained in the design of analog circuits. Working in a R&D/Design department, I like mathematical analysis, physics and beautifully produced documents. I started contributing to the StackExchange by asking questions on the TEX.StackExchange, but soon I posted answers to questions on mathematics and electrical engineering. At present I am still contributing and I like it. I think this community is capable to provide effective advice and help to students/scholars and practitioners/professionals alike, and this is one of the main reasons I want to be an active part of it. ©
