I am searching for programmer who can make online web based tool which will do the following: 1) manual data entry, 2) specific calculations (~50 formulas), 3) showing results of calculations 4) saving the results 5) presenting the results in graphical and table formats. The specific area is heat balances calculations for cement plants (kiln unit) which I am working for (chemical engineering area). I have a concept of how this tool should look like, I have all formulas (excel and guidance documents) and even started myself developing such tool in replit. I want to make it programmed in replit, so i can adapt in the future and use it in website to be used by myself and my colleagues.
