Hi,
After reading your requirements, I’m confident that I could deliver a platform that meets your expectations.
I’m a co-founder of a software company in Hanoi, Vietnam. We have built a number of complex platforms from scratch using C# as the main language. We built a HR portal for a company of 1500 employees that includes features such as Timesheet, payroll, Expense management, chart/report generation, etc. We also developed a cloud-based and standalone solution that provides traffic operators with a user management tool to monitor intersection performance via conditions set as alarms. The platform can provide many interactive charts rendered from the front-end for visualizing the huge amount of data for end-users. You can check out my portfolio via https://www.freelancer.com/u/NhungAI?page=portfolio&w=f&ngsw-bypass=
If this makes sense to talk, please let me know if you would like to schedule a call this week.
Kindly be noted that the proposed timelines and budget are just placeholder and open for negotiation to increase or decrease as per the full requirements at hand.
Thanks and regards,
Nhung
