I'm a spreadsheet engine developer with 8+ years of experience in building excel data systems.And I am a 13 years+ web font developer.
I specialize in:
- Spreadsheet core architecture
- Pivot table engine design
- Chart rendering systems
- Shape & drawing infrastructure
- Excel compatibility (including XML parsing & rendering)
- High-performance data processing
I enjoy building structured, scalable, and deterministic systems — especially those that handle complex data transformations and visualizations.
Currently working on building a powerful open-source spreadsheet ecosystem.
Always interested in deep technical discussions.
