What I'm looking for

I’m looking to build scalable AI infrastructure and full-stack platforms on Kubernetes/AWS, optimizing GPU performance and latency while improving reliability, developer experience, and deployment speed.

I’m a Senior Software Engineer who architects and ships production-grade AI platforms. At Together Al, I built a full-stack AI cloud platform to train, fine-tune, and deploy large AI models at scale—supporting 200+ open-source models and thousands of inference requests per second, with a 2.5x throughput improvement and 40% lower model latency.

I also design scalable distributed training and multi-tenant backend services, including GPU cluster orchestration, Kubernetes inference APIs, and dataset pipelines. Previously at AWS, I helped deliver core cloud infrastructure and machine learning platform capabilities (Amazon EKS and SageMaker), improving training time by 45%, reliability to 99.99%, and reducing incidents by 30% while mentoring and collaborating across engineering and research teams.
