Zero external dependencies
What Was Built
- Engineered a zero-dependency custom Excel-like computation engine, completely eliminating the organization's reliance on legacy spreadsheet workflows.
- Architected a regex-based tokenizer and a dependency graph utilizing topological sort to ensure precise, stale-free recalculation of dependent cells.
- Enabled dynamic custom variables with automatic propagation of updates across 300+ rows × 20 columns of highly interdependent financial data.
- Integrated the computation engine seamlessly into the admin panel as a modular layer for real-time freight rate calculations, P&L projections, and insurance costing.
