Hi, I'm Shiva Kar, a Bachelor of Computer Applications (BCA) student at Amity University Online from Assam, India.
My primary focus is Java Backend Development, building scalable backend applications using Java, Spring Boot, Hibernate/JPA, REST APIs, and PostgreSQL.
Alongside backend development, I enjoy systems programming in C, building projects that deepen my understanding of operating systems, memory management, networking, and software internals.
I also build AI-powered applications by integrating modern LLMs, coding agents, and workflow automation into real-world software. My focus is on using AI effectively to build better applications—not training machine learning models.
Outside backend engineering, I enjoy building indie games with Godot and occasionally Unity, contributing to open-source projects, and continuously improving my software engineering skills.
