Jaskaran Singh User

I am a Full-Stack Web Developer with 2+ years of freelance experience delivering production-grade applications for clients in fintech and AI. I independently manage projects from design through deployment and prioritize performance and reliability.

My core strengths include React, Next.js, TypeScript, and Node.js, complemented by hands-on experience with AR integrations, Three.js, and real-time systems using WebSockets. I also leverage backend frameworks like Express.js and FastAPI to build scalable microservices.

Notable achievements include deploying and customizing open-source platforms for a banking dashboard, redesigning an AI product UI to improve usability, and optimizing media pipelines to eliminate rendering lag. I built a browser-based AR glasses try-on delivering 45 FPS real-time rendering and a synchronized multiplayer game using WebSockets.

I focus on clean, maintainable code, performance optimization, and integrating APIs and tools such as Firebase, MongoDB, Prisma, Docker, and Google Mediapipe. I seek roles where I can drive end-to-end product development and contribute to impactful, user-focused software.
