Definitely, This is the best Developer ever at goo experience and friendly behavior to deal with all the time. He cares about the project and he make sure project is working before he gets pay. I trust me all the time and stay late hours working to solve any issues or dislike with design. I love this Developer and I will always ask him for advice on many other projects before wasting my time and money. well done!
Great Developer, fast and with full knowledgeable about C++ and ESP8266 modules. Definitely I will always ask this developer to do all my new projects.
