Phat Nguyen is a great freelancer. Quick and efficient and provided a rapid solution with really good follow up support. It was a small job, but it will hopefully lead to more work. He is highly recommended.

Toby Hart

UK Customer

We have worked with Phat to complete our project on IoT. We needed some customized Firmware for running our parts. Phat was able to code everything very efficently and with a very result driven mentality. He was very welcome, and helped us along the way. He solved the many issued which come up during our development iteneration, eventhough he was not responsible for them.

Lorenzo Querci

Italy Customer

Phat planned his time well and put real thought into how to address the problem well before winning the contract. We had local resources which helped with the timezone and language but Phat made himself available to support our needs.

Malcolm Wild

UK Customer

Phat completely rewrote our Arduino based firmware in a very professional way and added a lot of new features. Highly recommended freelancer!

Achim Haug

Thailand Customer

Phat was extremely organized and that enabled us to communicate clearly and easily. The software he developed for our product was well-architected and is maintainable after delivery. He consistently hit deadlines and has the technical depth for embedded systems to resolve items on his own based on schematics/testing and make suggestions/implement improvements. He was flexible in working with us as our project scope changed over time. We will work with him again in the future.
