Ralph D.

"Ralph helped with various projects and he's been a pleasure to work with. He also has been a resource of knowledge that I have been able to tap on."

"Unable to gauge freelancer's work as we have not had any deliverable. Due to slow progress we had to cancel project as project deadline was missed."

"Well done - consultant had all required skills and deep knowledge on the topic"

"Working with Ralph was unbelievably great. He took an old project from an engineer that left abruptly to breathe new life into the project. Not only figuring out what was poorly documented but also suggestion and implementing cost-reducing changes that improved our devices overall functionality. We have not yet come to a final version of the device so I can't speak to manufacturability, but this is due to our internal processes and has nothing to do with Ralph's work. I highly recommend Ralph for PCB design, circuit design and firmware development. He is up to date on the ecosystem and documents his work very thoroughly. He is also a great communicator and easy to work with. We will certainly be working with Ralph in the future."

No feedback given

"Ralph is a kindly freelancer to help me solve my project, 5 stars recommend to you!"

"This was my first experience working with a remote freelancer, and Ralph made the process very pleasant. His work & knowledge far exceeded my expectations, and as a result we were able to complete my project ahead of schedule. He was seemingly always available, and provided daily updates. We spoke often via Skype, and his English is very good. I am now confident that many more of my projects would benefit from Upwork, and I intend to hire Ralph again immediately to expand on the work that he has already done."

"Good combination of soft- and hardware engineering."

"While we didn't end up needing Ralph, he was very helpful during the beginning of our project and provided lots of valuable feedback about our design direction and project specifications. Clearly he is a seasoned embedded developer and somebody we would certainly consider hiring again should the need arise."
