  • goldenpathsolns的图片 Migrate Java applet to JavaScript: a tool for defining direction of travel in agricultural fields $1500.00 USD

    “Overall, the project was executed well, and added value to my business. The product generally met the requirements, although there were some issues that we weren't able to iron out in the time that I had, we were very close on delivery. I ended up doing some rework to make the product production-ready. I was able to handle those changes within a day, and the cause of those issues could be attributed to a lack of clarity in the initial requirements I provided. The developer clearly worked hard to understand my needs, communicated frequently and was quick to ask questions when needed. They put in long hours, and overall, communication was very good. The product was well written, easy for me to maintain, and showed good proficiency.”
