Honest, clear, and capable.

Rajesh complete a job for me that involved creating a form in ASP.Net core that captured user information and a photo for upload to a SQL Server table for review. I especially appreciated his willingness to tweak the deliverable to ensure it met the requirements of the job.

My initial review for Rajesh was limited because he requested time to review the problem after my providing some details. That reflects his honesty - he is not charging while doing some research. Following this I hired Rajesh to implement PayPal for our organization. He returned the updated project with clear, functioning code on time. His communication during the development was excellent, allowing me to efficiently and effectively collaborate with him. In this session today he guided me in cutting over from Sandbox to Live account processing. I could not be happier and certainly will be working with Rajesh to solve future code challenges!
