Macro Enhancement and Calculation Revision

I am seeking a proficient Excel expert to enhance macros within an existing spreadsheet. My primary concern involves re-scripting macros for performance enhancement. On top of this, the spreadheet needs to have its calculation functions updated in certain areas. Hence, the ideal candidate should be comfortable in tweaking and improving formulas for better functionality. I also anticipate that some redundant aspects of the macros may be stripped off as we progress to streamline performance.
Required Skills:
- Proven Macro scripting and implementation in Excel
- Solid understanding and experience in complex formula manipulation
- Ability to optimize spreadsheet for improved performance and efficiency.
Note: Specific deliverables relating to the calculation changes will be shared during our one-on-one project discussion.
