Dear sir
Thank you for giving me this opportunity to bid on your project. I read your job requirement and wish I can work on your project.
I have rich experience in the app developments with c#, and I'm able to build your project to satisfy you. You can be sure and believe me if you test my skills directly.
I have completed 100+ USSD applications which include Ghana's Health application and MastercardFoundation sponsored applications and also working as a team lead for the Ghana-based payment gateway.
I was also part of PCI compliance.
Along with above I also work on Oracle (in which most of our business logic is written) and MSSQL.
I never disappoint clients and their benefits come first. I provide a qualified and trustworthy long-term service. I hope you contact me to discuss more in detail on your project. I can also show my work on your request.
Regards
