MCA Student at NIT Jamshedpur passionate about building scalable backend systems, cloud-native applications, and AI-powered developer tools using Spring AI, RAG, and vector databases.

• 💻 Currently building Distributed CodeForge, a cloud-native agentic coding workspace with self-healing compiler loops.
• 🚀 Passionate about Backend Engineering, Distributed Systems, Cloud-Native Architecture & Generative AI.
• 🤝 Looking to collaborate on Java, Spring Boot, Spring AI, Kubernetes & Open Source Projects.
• 🌱 Currently learning AI Evaluation, LLM Quality Improvement & Agentic Systems.
• 💬 Ask me about Java, Spring Boot, Spring Cloud, Kafka, Kubernetes, PostgreSQL, Redis, RAG/pgvector, and DSA.
• 🏆 LeetCode contest rating 1739 (Top 11% globally), 1,150+ DSA problems solved across platforms.
• ⚡ I enjoy shipping production-grade backend systems with real deployment pipelines, not just prototypes.

Cloud-native, agentic collaborative coding workspace built with Spring Boot, Spring Cloud, Kafka, Kubernetes, React, and Spring AI.

• 6-microservice control plane across network-isolated K8s namespaces for secure runtime sandboxing
• Cut sandbox preview spin-up latency 90% (15s → <1.5s) via a pre-warmed K8s runner pod pool + Redis route caching
• Self-correcting agentic feedback loop using Spring AI tool calling to run builds and auto-resolve compiler errors via pgvector error-fix memories
• 5 path-filtered GitHub Actions workflows with Jib (daemonless builds) + keyless GCP Workload Identity Federation
• Stripe-powered subscription billing with token usage quotas and locked-down sandbox network egress

Hospitality reservation REST API built with Java, Spring Boot, PostgreSQL, Stripe, and Spring AI.

• 90+ source files, 25+ tests, clean layered architecture with a Decorator-pattern pricing engine
• Signature-verified Stripe checkout + transactional refund handlers with DB-first state persistence
• Pessimistic locking on room inventory to eliminate double-booking, plus a scheduled job expiring unpaid reservations every 5 minutes
• 3 Spring AI integrations: dynamic pricing, semantic property search, and a review Q&A chatbot (pgvector-backed), each with fallback handlers
• HttpOnly JWT cookies, BCrypt hashing, RBAC, and token versioning for global sign-out on password reset
