Vardaan Lamba

I’m a Senior Backend Software Engineer with 5+ years of experience designing, building, and scaling high-performance distributed systems using Java, Spring Boot, Kafka, and microservices architecture. I’ve improved API response times by ~40% through Redis caching and targeted SQL query tuning, and I deliver production-grade solutions for enterprise clients with a strong focus on reliability and backward compatibility.

I also build event-driven, resilient systems using Kafka-based asynchronous pipelines and resilience patterns (retry, circuit breaker, bulkhead, fallback) via Resilience4j. Beyond backend engineering, I strengthen delivery and operations with CI/CD automation (Jenkins, Docker), Kubernetes deployments, and observability practices that reduced production MTTR. Currently, I’m deepening expertise in Retrieval-Augmented Generation (RAG) with LangChain4j and vector search, and I mentor engineers through code reviews and KT sessions.
