Open to Internship & Remote Opportunities
Hi, I'm Yuvraj Singh Jadaun
Full Stack & Blockchain Developer
Building scalable web applications, backend systems, and decentralized technologies.
Building scalable web applications, backend systems, and decentralized technologies.
I am a third-year Computer Science student focused on full-stack development, backend engineering and blockchain technologies.
I enjoy turning ideas into working products and understanding how each layer connects, from a clean interface to an API, database and deployment.
Backend systems and scalable APIs
Learning stronger architecture, validation and production-ready workflows.Clarity, consistency and useful software
I prefer understanding the fundamentals and shipping honest, maintainable work.Programming foundations for systems, web applications and problem solving.
Everyday tools for writing, testing and managing software projects.
Frameworks and API technologies for modern full-stack applications.
Data storage and caching technologies for reliable application backends.
Tools for containerization, deployment and managing cloud environments.
Habits that help me contribute clearly and consistently in a team.
A selection of projects that showcase my software engineering, backend development, and blockchain journey.
AI-powered web application that analyzes previous year RTU papers, predicts important topics, generates expected question papers and provides an AI assistant for students.
Problem: Students need a faster way to identify repeated topics in large collections of RTU papers.
Approach: Build a backend that extracts paper content, organizes topics and uses AI to generate focused revision material.
Next milestone: Complete the paper ingestion pipeline and evaluate predictions against previous exams.
A full-stack Todo application with secure user authentication and personal task management. Users can register, log in, and perform CRUD operations on their tasks through a RESTful API. Built with a modular client-server architecture and MongoDB for persistent data storage.
Problem: Create a secure and simple platform where users can manage their personal tasks with persistent data storage.
Approach: Built a React frontend connected to an Express.js REST API, using JWT authentication and MongoDB for secure user-specific Todo management.
Next milestone: Deploy the application and add task priorities, due dates, search/filtering, improved UI, and production-level security.
Browser-based game developed using HTML5 Canvas and Vanilla JavaScript featuring collision detection, scoring and responsive gameplay.
Problem: Create a responsive browser game with immediate feedback and consistent gameplay.
Approach: Used the Canvas API for rendering, a game loop for motion and collision detection for obstacles.
Engineering lesson: Balanced frame updates, scoring state and responsive input in a small client-side system.
Collection of decentralized applications built while learning Solidity, Ethers.js and blockchain development.
Goal: Learn how decentralized applications connect a browser interface to smart contracts.
Approach: Explore Solidity contracts and wallet interactions through Ethers.js and Web3.js.
Next milestone: Ship one focused DApp with tests, transaction states and clear error handling.
A closer look at the full-stack contact workflow running behind this site.
The browser trims the input, checks required fields and validates the email before making a request.
The form sends a JSON POST request to /api/contact on the deployed Express server.
The controller checks that name, email, subject and message are present before continuing.
A Mongoose model stores the contact with trimming, length limits and automatic timestamps.
Resend sends the notification to the configured destination and reports failures back to the API.
Validation happens in both the browser and backend. The database schema adds a second boundary with required fields, trimming and maximum lengths, while the API returns clear success and error responses.
Actively contributing to open-source projects, collaborating with maintainers and improving software through meaningful pull requests.
Building projects consistently while improving backend engineering, web technologies and software architecture.
Passionate about teamwork, clean code, documentation and contributing to developer communities.
