I'm a developer focused on building real-world products — combining full-stack engineering, system design, and AI to create scalable and useful applications.
Hey, I'm Sayan Dey , a Computer Science student and developer who enjoys building things that actually work in the real world.
I started with problem solving and Data Structures & Algorithms, where I built a foundation in thinking logically and breaking down complex problems. Over time, I transitioned into full-stack development — not just to learn frameworks, but to understand how real systems are designed and shipped.
I've worked on projects like a full-stack Airbnb clone, a blog platform with authentication and admin workflows, and a real-time chat application using WebSockets and Redis and this website also. These projects helped me move beyond tutorials and start thinking like an engineer.
Currently in my third year of Computer Science, I'm exploring backend architecture, DevOps practices, and AI integration — building systems that are not only functional, but scalable and production-ready.
Building end-to-end applications using Next.js and the MERN stack — working across frontend, backend, and databases. I focus on authentication systems, API design, and creating production-like features rather than just demo apps.
Designing scalable backend systems with Node.js, Express, and databases like MongoDB , PostgreSQL and Redis. I explore system design concepts like caching, real-time communication (WebSockets), and performance optimization.
Building AI-powered features using LLM APIs, RAG pipelines, and agent-based workflows. I experiment with agentic AI systems where multiple models and tools interact to solve complex tasks inside real applications.
Continuously learning backend, DevOps, and advanced engineering concepts with a long-term goal of building impactful products.
Technologies and tools I use to design , build and scale modern applications.
I'm not just aiming to get good at coding — I want to become someone who can design, build, and scale complete products from scratch. My focus is on becoming a strong engineer with the ability to turn ideas into real, impactful software.
