Fix Calendly event not showing availability (quick job)
Janinam was very committed to getting this project done correctly. It was a challenge at times to understand his English. HOWEVER, he was patient with me (as I was with him) and we worked through everything perfectly. I understand Janinam is relatively new to Upwork but I had a very positive experience with him.
