  • hình của Shtm Electrical engineer needed to convert a functional specification into a circuit design based around the ESP8266 -- 3 $15.00 USD

    “Khaled did a good job. Doubtless Khaled will be disappointed that he did not receive all 5-star feedback for this project. I realize that many clients provide all 5-star feedback to freelancers unless they are very dissatisfied. Please do not look at the lack of 5 star rating as any sort of harsh criticism of Khaled but rather my honest feedback. I paid another engineer to review Khaled's submission. The other engineer indicated several points about Khaled's submission. The one point I am willing to share is, "Reasonable design proposal." Like I indicated at the beginning, Khaled did a good job. Will I work with Khaled again? Probably not. I am looking to work with engineers whose submissions we (another engineer and I) judge to be at least “very good.” In other words, “good” is not good enough for me.”
