About

Backend Engineer | 4+ years | Java, Kafka, Spark, Kubernetes, GCP & AWS With over 4 years of experience building scalable backend systems, I design systems that scale, optimize the ones that don’t, and debug the ones that misbehave. At Flipkart, I’m part of the CRM-Connekt team, where I build large-scale, reliable notification platforms that power 500M+ daily active users across email, SMS, and push channels. I focus on high-throughput, low-latency distributed systems using Apache Spark, Kafka, Kubernetes, and GCP. Some recent highlights: 1. Revamped Flipkart’s message and notification systems—enhancing performance and personalization through Spark optimizations, leading to 150K QPS throughput gain, 60% storage reduction, and 30 bps uplift in engagement. 2. Led GCP migration (Airflow, Dataproc, GCS), improving scalability, performance, and cost-efficiency. 3. Ran large-scale load tests ensuring platform stability for 400M+ users during Flipkart’s peak sale events. 4. Built monitoring and alerting dashboards to minimize downtime via proactive issue detection. 5. Winner – Flipkart's Hackday 11 & Gen AI Hackathon for rapid delivery and innovation. Whether it's crafting HLD/LLD, improving observability, or solving tough production issues, I thrive in backend problem-solving and driving systems to operate smoothly at scale.
