“He knows his stuff (i.e. he knows what he's doing, unlike others). My project would have ended in disaster if he was not around. Thanks for your help! :) I highly recommend this freelancer. I'm sure I'll approach him if I have other projects like this.”Gene Carlo D. hace un año

“Stuart made a good job and have good knowledge in dc-dc”or682 hace 2 años
PCB Redesign - mSATA dual adaptor to USB
“Stuart placed an offer on my project like few others, but unlike most, he gave me a realistic picture of the upcoming costs and a better understanding of the expected bumps in the road ahead, plus a clear vision of how and when the job will get done. We set the deadline of 10 days for the first job and he was on it from the first second. Not a question left unanswered or an issue of concern unaddressed before and during the work. I found him available online almost all the time even with a big time difference between our locations, which certainly is a great help. Moreover, and on the top of his expertise in electronics and PCB design, Stuart has a great understanding of the business side of the story, and that is a huge advantage. Having no proper knowledge of electronics and PCB design, I started to get a bit worried at first when sometimes conversations seemed too technical for me, but he was explaining terms in plain English and I learnt a lot from him. He delivered a great looking design on-time and he provided (and still providing) amazing level support in every aspects. With Stuart, you would have an experienced, knowledgeable expert on your side and I am glad to highly recommend him. And I am looking forward to work with him again on my other projects.”BruceRichard hace 2 años
