Experience

Food Subscription SPA Application

https://omnifood-nepal.netlify.app/
Omnifood Nepal is a fully responsive, high-performance landing page for a fictional food delivery subscription service. The project focuses on delivering a modern, user-centric UI/UX with sections such as features, meal plans, testimonials, and pricing to simulate a real-world SaaS product.

I designed and developed the entire front end using HTML, CSS, and JavaScript, emphasizing performance optimization, accessibility, and SEO best practices. The application achieves high Lighthouse scores (95+), with optimized assets, responsive layouts for all devices, and smooth interactions.

This project demonstrates my ability to build production-quality marketing websites with clean architecture, reusable components, and attention to detail in both design and performance.

Quiz Builder Application

https://quiz-frontend-rho-eight.vercel.app
This is a full-stack quiz-building platform that lets users create, manage, publish, and share interactive quizzes via unique links. I built the front end with React (Vite) and the back end using NestJS with PostgreSQL. The application includes authentication, protected routes, dynamic quiz creation flows, and REST APIs for managing quizzes and responses. I paid close attention to clean architecture, state management, and reliable communication between the front end and back end. The front end is deployed on Vercel and the back end on Railway.

Portfolio Website

This is my personal portfolio website where I showcase my projects, technical skills, and professional experience. I designed and developed the site with a strong focus on performance, accessibility, and clean UI/UX. It includes project, responsive layouts, and optimized assets to ensure fast load times across devices. I paid close attention to structuring content clearly and making navigation intuitive, while keeping the design minimal and modern. The project reflects my approach to building polished, user-focused front-end applications.
