Mentorship

PDF Compare Tool

I have mentored a team of 3 students in the development of a PDF compare tool using ReactJS, HTML, CSS, and JavaScript. The tool allows users to compare two PDF files and highlight the differences between them.
PDF Compare Tool is a utility that allows users to efficiently compare the contents of two PDF documents. It highlights textual differences, formatting inconsistencies, and layout changes to help users identify edits, revisions, or errors between versions.

HTML Editor for Open-EdX Courseware Management System

A custom-built HTML content editor designed specifically for Open-EdX CMS and LMS platforms. Enables course creators to easily edit and preview content blocks using a user-friendly interface, reducing dependency on raw HTML and minimizing formatting errors.

Peer Assessment Tool for e-learning platform

Designed and developed a Peer Assessment Tool integrated into an e-learning platform to facilitate student-driven evaluations. This tool enables learners to review and provide constructive feedback on peer submissions, promoting collaborative learning, critical thinking, and engagement within online courses. The system supports customizable rubrics, anonymous reviews, and automated scoring summaries to streamline instructor workload and enhance learning outcomes.

e-Book for Aakash Tablet

Developed an e-book for Aakash Tablet, a 7-inch Android-based tablet designed for education. The e-book features interactive content, multimedia elements, and a user-friendly interface to enhance learning experiences on the device.
The e-book was developed using HTML5, CSS3, and JavaScript, and was designed to be compatible with the Aakash Tablet's screen size and resolution. The e-book also features a user-friendly interface, with a navigation bar at the bottom of the screen, and a sidebar for quick access to different sections of the e-book.

The platform allows users to create, edit, and share animations using a drag-and-drop interface. The animations can be used in e-learning courses to enhance the learning experience.

Interests

When I'm not coding, I love being outdoors—especially during the monsoon and winter, exploring roads on my car or bike. In the colder months, I also enjoy working in my hometown fields.
Indoors, I unwind with suspense, thriller, and horror films and dive into the latest trends in front-end web development, I'm passionate about exploring the latest innovations in cars, bikes, and mobile tech.

PROFESSIONAL VALUE PROPOSITION

I bring a combination that is especially valuable for technology-driven product teams:
Product Thinking + Engineering Understanding + UX Awareness + Delivery Ownership

I can communicate with business stakeholders about what should be built and why, while working with engineering teams to understand how it should be built, its technical constraints, dependencies, APIs, architecture, testing requirements, and scalability considerations.

This allows me to operate effectively between:
Business ↔ Product ↔ UX ↔ Engineering ↔ QA ↔ Stakeholders

and help teams deliver products that are technically practical, user-focused, measurable, and aligned with organizational objectives.
