Description: I’m looking for a talented JavaScript developer who can build a custom calculator engine that can power hundreds (eventually 1,000+) of calculators on my website. The goal is to create a high-performance, scalable calculator platform — similar to Omni Calculator or Calculator.net — where each calculator (like BMI, EMI, SIP, Age, Percentage, etc.) is generated dynamically using configuration files (e.g., JSON). Responsibilities: Develop a modular JS calculator engine that can render calculators dynamically. Each calculator should be generated using a simple config file (JSON) defining inputs, formulas, and outputs. Integrate the calculator system into WordPress pages via shortcode or script embed. Ensure fast load speed, responsive UI, and clean design. Build the first 30 calculators as part of the initial phase. Provide clear documentation for adding more calculators easily in the future. Requirements: Strong skills in JavaScript, HTML, and CSS. Experience with dynamic form generation and formula-based tools. Understanding of WordPress integration (enqueue scripts, shortcodes, etc.). Good code structure, modular thinking, and attention to detail. Bonus: Experience with TailwindCSS, Chart.js, or other lightweight libraries. Phase 1 Deliverables: Fully functional JS calculator engine. Integration setup with WordPress. 30 calculators implemented (e.g., BMI, EMI, SIP, Age, Percentage, etc.). Documentation for adding more calculators.
