About

Professional summary

I am a backend-focused Software Development Engineer with hands-on experience building enterprise Java services, REST APIs, real-time applications, and AI-powered full-stack products.

I currently work as an Associate System Engineer at Tata Consultancy Services, where I develop Spring Boot services and support CyberArk Privileged Access Management operations. My work includes secure session-review workflows, privileged-account onboarding, Vault configuration, production support, and troubleshooting.

I have strong foundations in Java, JavaScript, TypeScript, Python, data structures and algorithms, system design, distributed systems, database optimization, and cloud development on AWS. I enjoy designing scalable backend systems with reliable APIs, search, filtering, caching, and performance-focused data access.

I have built RAG-based applications using LangGraph, Pinecone, Cohere embeddings, MongoDB, and LLM integrations. I also developed real-time collaborative editing experiences using Socket.IO, WebSockets, React, Node.js, TipTap, and ProseMirror.

I am AWS certified and have demonstrated competitive programming proficiency through over 1,000 LeetCode submissions and 150+ GeeksforGeeks problems. I am interested in backend, full-stack, cloud, AI application, and cybersecurity engineering opportunities.
