Building scalable apps with
Next.js, Node & AI Systems
I am Sanjay S, a 2025 Computer Science Engineering graduate with hands-on experience developing end-to-end applications across the modern stack — from responsive front-ends to scalable backend logic, relational & document databases, and AI automation.
About Sanjay S
Get to know the developer behind the code — academic foundations, technical principles, and engineering mindset.
Engineering Profile & Mindset
A 2025 Computer Science Engineering graduate (Fresher) with a solid foundation across front-end, back-end, and database technologies, along with practical experience building complete, working applications. Comfortable working across the stack — from designing clean, responsive interfaces to building server-side logic and managing data. Eager to start my career as a Developer and contribute to a team through strong fundamentals, adaptability, and a genuine interest in problem-solving.
Having earned an 83% aggregate in Computer Science & Engineering at Arunai Engineering College, I pair fundamental computer science principles with hands-on modern stack development (React, Next.js, Node.js, Express, Java Servlets, MySQL, and MongoDB).
