Aadhaar Goel
Full Stack Developer & Competitive Programmer
I design and build scalable backend systems with clean, maintainable code and thoughtful architecture. From secure authentication to event-driven microservices, I enjoy turning complex problems into reliable, production-ready web services.
Background
I’m a software developer with strong foundations in Data Structures & Algorithms (C++), backend engineering, and full-stack development. I’m currently pursuing a B.Sc. (Hons) in Data Science & Artificial Intelligence at IIT Guwahati.
I enjoy developing scalable, real-world applications across different stacks. I’ve built Spring Boot–based backend systems with secure authentication, REST APIs, and microservice-style architectures, as well as a full-stack MERN e-commerce platform featuring payments, email automation, and cloud deployment. I prioritize writing clean, efficient, and reliable code.
I’m also a Codeforces Specialist, reflecting strong problem-solving and algorithmic thinking. I’m seeking Software Developer, Backend, or Full-Stack internship opportunities where I can contribute to impactful projects and continue growing as an engineer.
