About Wong
(Google Sheets) Sales Automation & Spreadsheet System Designer
Kuantan, Malaysia - 6:32 pm local time
I specialize in building system-level spreadsheet solutions, not basic one-off templates or manual data work.
My work focuses on designing reusable and scalable Google Sheets systems, including:
• Data Entry Systems with structured input flow and error prevention
• Data Quality Control (QC) Systems to detect duplicates, missing data, and data status issues
• Sales Data Automation Systems where data is entered once and automatically flows into summaries and dashboards
These systems are designed to reduce manual checking, minimize human error, and give users clear visual indicators (such as status flags and QC layers) to quickly identify data issues.
Unlike basic spreadsheet setup, my systems emphasize:
• Clear separation between raw data, QC logic, and reporting layers
• Reusable formulas and scalable structure
• Long-term usability for growing datasets and recurring workflows
This approach is suitable for businesses handling customer lists, leads, sales records, or internal reporting that require consistent data quality and reliable automation.
I usually work on fixed-price system projects, depending on scope and complexity.
If you already have a workflow or data problem in mind, feel free to describe it — I can advise whether a system-based solution is the right fit.
