Hi, I'm
SiddharthSingh. — Full Stack Engineer
I architect secure, role-based enterprise systems.
Full Stack Engineer specializing in React, Java, Node.js, and Spring Boot. I build robust REST APIs, automate enterprise workflows, and translate complex backend logic into seamless front-end experiences.
About Me.
I build full-stack applications end-to-end, specializing in Java/Spring Boot and Node.js backends seamlessly connected to modern React frontends via asynchronous data retrieval.
My focus is on creating secure, enterprise-grade systems with robust authentication (JWT), Role-Based Access Control (RBAC), and optimized SQL databases handling thousands of concurrent interactions.
I am currently completing my Master of Computer Applications (MCA) at Adamas University while consistently solving advanced Data Structures and Algorithms problems to sharpen my computational logic.
