Hi,
I can create a calculator similar to the one you are having in Excel using javascript. Pls let me know whether the values have to be saved or just calculation is enough.
Pls PM me to discuss further details.
I have 3+ years of front-end devlopment using HTML, CSS, JS, jQuery, Bootstrap and AngualarJS. I am proficient programmer in asp.net and php also. I can assure you that I will provide quality work in given time period without any issues. The final code will be delivered with comments and documentation.
Looking forward to work with you,
Kasi
