Varshitha GR

I’m a Senior Software Engineer with 11.5 years of hands-on experience building and delivering highly scalable distributed systems, microservices, and event-driven architectures on Amazon Web Services (AWS). I focus on system design, code quality, performance optimization, and reliability—especially in high-throughput backend environments.

At Saks Global (Hudson's Bay Company), I architected and built AWS microservices (ECS/EKS) with Apache Kafka processing 1M+ daily transactions (5M+ peak), designing for high availability, fault tolerance, and reliability. I also integrated AI/GenAI into production backend systems by building a RAG-based LLM pipeline using HuggingFace Transformers for support automation.

I lead engineering through system design and code reviews, setting standards and mentoring engineers on distributed systems, ML integration, and cloud-native practices. I own system reliability and observability, maintaining 99%+ platform availability through Datadog monitoring and providing Level 3 (L3) production support with SLA adherence.

I’ve driven measurable outcomes by reducing integration latency by 20-30% through performance analysis and legacy re-engineering, and by accelerating GenAI tooling adoption via PoC evaluations. Earlier at Tata Consultancy Services, I built enterprise-grade integration systems using IBM IIB and IBM MQ, modernizing legacy batch to event-driven architectures and earning early promotion and multiple performance awards.
