Platform-focused software engineer building Ray-based distributed GPU and LLM inference systems.

What I'm looking for

I want to build and operate scalable distributed platforms for LLM and data workloads—owning architecture, performance, cost attribution, and observability—so teams can ship production pipelines fast with strong infrastructure and developer experience.

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.
