Experienced Bootstrap Developer Needed for Responsive Web UI Project

We are looking for a highly skilled Bootstrap Developer to create modern, responsive, and visually polished front-end interfaces for our web application. The ideal candidate must have deep experience with Bootstrap 4 and Bootstrap 5, mobile-first development, cross-browser compatibility, and clean, accessible UI implementation.

Your primary role will be to convert Figma/Adobe XD designs into pixel-perfect frontend layouts using HTML5, CSS3, Bootstrap utilities, components, and responsive grid systems. You should have a strong understanding of layout techniques, spacing utilities, custom themes, SASS variables, animations, and how to optimize UI performance without compromising quality.

This project involves building pages, reusable components, navigation systems, forms, modals, tables, cards, and dashboards. You will collaborate closely with backend developers to integrate APIs, ensure seamless interactions, and maintain consistent design across the entire application.

A successful candidate will understand how Bootstrap interacts with custom CSS, JavaScript plugins, and responsive breakpoints. Strong attention to detail is required — every component should feel polished, aligned, and intuitive.

You must be comfortable debugging layout issues, optimizing for Core Web Vitals, handling device testing, and ensuring performance across all major browsers (Chrome, Edge, Firefox, Safari). Familiarity with accessibility guidelines, ARIA labels, and semantic HTML is essential.

If you’re passionate about building clean, elegant, and responsive web interfaces, this project will be a great match. The work will follow weekly milestones and structured delivery, with clear expectations for quality, documentation, and performance benchmarks.
