Calculate Central - Online Calculator Toolkit
Overview
Calculate Central is an online calculator toolkit designed for high-frequency and professional calculation scenarios.
It focuses on encapsulating complex formulas, business rules, and multi-step workflows into intuitive user interfaces so that users can complete advanced calculations directly in the browser.
Technical Challenges
The core challenges of the project lie in performing accurate calculations on complex formulas while keeping the UI responsive and performant.
- Handling high-precision numeric operations in the browser to minimise floating-point errors.
- Designing an extensible computation module so that new calculators from different domains can be added over time.
- Maintaining smooth interactions and good perceived performance even under frequent user input and recalculation.
Tech Stack
- TypeScript + React / Next.js for the frontend interface and routing.
- A modular calculation engine that abstracts formulas and validation logic for each calculator.
- Modern frontend tooling and optimisation techniques for bundle size and runtime performance.
