Platform-focused software engineer building Ray-based distributed GPU and LLM inference systems.
IndiaWhat I'm looking for
I’m a Software Development Engineer on Visa’s Batch Platform team, where I built a Ray distributed compute engine from scratch on Kubernetes (KubeRay) with GPU scheduling and autoscaling, integrating it with Apache Airflow and Hadoop (HDFS, YARN) for petabyte-scale workloads.
I’ve benchmarked Ray vs. Spark for LLM inference, re-architected production analytics into a distributed Ray agentic workflow across LangGraph nodes, and designed a GenAI SDK that tracks tokens per DAG/task/node for first-time cost attribution. I also built observability (Grafana, Splunk, LangSmith) and help teams ship production pipelines end-to-end through platform SDKs, design reviews, and onboarding.
