Develop 50 Custom Code Calculators for WordPress (HTML, CSS, Bootstrap, React, Python – No Plugins)

I'm looking for a professional full-stack developer to build 50 custom-coded calculators for my WordPress website. The calculators must be developed from scratch using HTML, CSS, Bootstrap, React (for UI), and Python (for logic if needed). No plugins should be used—clean and custom code only.

Tech Stack to Be Used:

Frontend: HTML, CSS, Bootstrap 5, React

Backend (where required): Python

No use of WordPress plugins – everything must be integrated using custom code

Project Requirements:

Build 50 unique calculators for different niches (e.g. finance, health, digital tools, unit converters, etc.)

Fully responsive and optimized for mobile and desktop

Match my preferred design:

Dark theme

Left-side input / right-side result layout

White font with #1E3A5F button and accent colors

Calculators must be easy to update, extend, and maintain

Fast-loading, SEO-friendly, and cleanly written code

All source code must be well-structured and documented

Example Calculators:

Loan Calculator

BMI Calculator

Bandwidth Calculator

Hexadecimal Converter

Sample Size Calculator

Calorie Intake Calculator
(I will provide the full list of 50 calculators after hiring)

Ideal Developer Should:

Be highly skilled in React, Python, and WordPress integration

Know how to work without plugins in a WordPress environment

Have experience building custom tools and calculators

Be detail-oriented and deliver high-quality, production-ready work

I’m ready to start ASAP with the right developer. If you've built similar tools before, feel free to share links or examples.
