An interactive resident AI agent trained on Anirban Kar's backend engineering stack, Java 21 architecture, featured repositories, and real-time portfolio navigation.
I am a backend-focused software engineer based in Bengaluru, Karnataka. My primary fascination lies in building software systems that remain responsive, scalable, and resilient under demanding enterprise workloads.
From diagnosing multithreaded contention and heap anomalies in the JVM to designing idempotent RESTful APIs and structured relational data architectures, I enjoy translating complex operational challenges into maintainable, elegant code.
When not writing Java or Node services, I experiment with interactive frontend experiences, Web Audio synthesis, and developer tools that streamline daily engineering telemetry.
Multithreading, thread pooling, and non-blocking IO design.
Idempotency, OpenAPI specification, JWT security, and resilient error patterns.
Docker containerization, reproducible builds, and automated GitHub CI/CD.
I am actively looking for Backend Engineering, Distributed Systems, and Java/Spring roles in Bengaluru or Remote.
