About

Senior Software Engineer with 6+ years building large-scale distributed systems and event-driven microservices across Retail and BFSI. Currently working on Tesco's Order Fulfilment System, where I design Kafka-based real-time systems and am now extending that backend depth into applied AI — building agentic systems, RAG pipelines, and ML models for production use cases. 🔹 Architected a multi-module AI agent platform (Java 21, Spring Boot, Next.js) using LangGraph4j for LLM-powered graph orchestration and Qdrant for Retrieval-Augmented Generation — automating software architecture compliance reviews with scored gap analysis. 🔹 Built and evaluated an ETA prediction ML model using Linear Regression, integrating LangChain to orchestrate LLM-assisted data preparation — bridging traditional ML with GenAI tooling in a production backend system. 🔹 Designed and delivered the Fulfilment Capacity Engine for Tesco's Order Fulfilment System — streaming real-time capacity and reservation data via Kafka to power store optimization and order volume monitoring at scale. 🔹 Led end-to-end design (HLD/LLD) and delivery of the ETA initiative for Whoosh (60-minute) orders — real-time order tracking APIs integrated with Couchbase and Kafka. 🔹 Built Samsbot from scratch (Core Java, Spring Boot) — an observability and alerting bot adopted across multiple teams at Walmart, integrated with CCM, Akeyless, and WCNP for secure CI/CD automation, extended to Slack and Microsoft Teams. 🔹 5+ years architecting event-driven microservices with Kafka, Kafka Streams, Couchbase, Oracle, and Azure DB — with recent focus on applying that distributed-systems foundation to agentic AI systems and GenAI-powered workflows Core stack: Java, Spring Boot, Apache Kafka | Databases: Couchbase, Oracle, Azure DB | Currently building with: LangChain, LangGraph4j, Qdrant (Vector DB), Python — applying backend engineering depth to LLM-powered agents and RAG systems.
