YuvrajI build systems that scale.

Strong command over JavaScript — from core concepts to advanced patterns like closures, async/await, and event-driven architecture across both frontend and backend.

Proficient in modern React — advanced hooks, context API, optimized form handling, and scalable component architecture. I build fast, maintainable UIs using best practices and performance-focused techniques.

Tailwind CSS is my go-to for styling — it streamlines my workflow by enabling utility-first design directly in markup. I use it to craft clean, responsive, and modern UIs efficiently.

After mastering frontend development, I dove deep into Node.js — building full-stack apps using core modules like fs, http, child_process, and cluster. I've developed scalable APIs, CLI tools, and handled real-world backend scenarios with performance and reliability in focus.

Skilled in building fast and scalable APIs using Express.js — with structured routing, middleware, and robust error handling in production-ready applications.

Proficient in MySQL — designing normalized schemas, writing complex queries, optimizing performance, and managing databases with PHPMyAdmin for scalable, data-driven applications.

Experienced with MongoDB — designing flexible schemas, optimizing queries, and handling large-scale data using Mongoose and the aggregation framework.

Proficient in using Redis for caching and session management — improving application speed, efficiency, and overall backend performance.

Proficient in BullMQ for building robust job queues and background processing — enabling reliable task scheduling, job management, and handling high-throughput data processing efficiently.

Hands-on experience with Azure VMs, Azure Blob Storage, and Azure CDN — building scalable cloud infrastructure, managing storage solutions, and optimizing content delivery for production applications.

Experienced in designing and developing microservices-based backends — with a focus on scalability, modularity, and clean communication using REST, BullMQ, and Redis.

Used it for hosting React static files and Node.js apps. Experienced in configuring reverse proxy, load balancing, SSL termination, and serving static assets efficiently.
