Project

Developed a web-based Offender Management System as my Master’s Project. I designed and implemented a responsive, accessible UI using HTML5, CSS3 (Flexbox/Grid, SASS), Bootstrap/Tailwind, and modern JavaScript (ES6+); built component-based interfaces and state management patterns, dynamic forms with validation, asynchronous data fetching (AJAX/Fetch), and interactive dashboards using Chart.js for data visualization while ensuring cross-browser compatibility and performance optimization. On the backend I implemented Python-based RESTful APIs, designed and optimized SQL schemas and queries for reporting, enforced authentication/authorization and data-privacy measure and prepared the app for AWS deployment with automated testing and CI/CD-friendly packaging.
