I am a graduate in Software Engineering and I have gained all the basic knowledge from my study. That’s why I knew many works related to web programming before entering this business.
I always meet deadlines. Never hesitate to make the best use of my skill and knowledge in order to complete a project successfully.
I believe I would be the best person in this project, and I am waiting for a positive response from you very soon. I am active on the internet.
Thank you for visiting my profile.
Vadim is not a great developer, he took a long time than expected but still did not complete it. Unfortunately wife got COVID and was in emergency situation that pushed me to release a huge amount without even getting the work completed. No new developer is accepting to fix it , as they say there are a lot of work pending ! Very disappointed and lost my money. I hope this money was used for his wife.
Great guy to work with. Every change I asked him to make, he did it. There were multiple iterations we had to go through to maintain the consistency, Vadim made all those iterations very easily. Thank you so much, Vadim.
