Staff Software Engineer specializing in full-stack, microservices, cloud and AI-enabled healthcare systems.
What I'm looking for
I am a Staff Software Engineer with deep full-stack and cloud-native expertise, focused on architecting scalable microservices and AI-driven systems for healthcare and data platforms. I have designed and operated HIPAA-compliant telehealth infrastructures, high-throughput data pipelines, and real-time analytics dashboards serving millions of users.
At Amazon, I led architecture and engineering for Amazon Health's telehealth platform, built NLP and clinical analysis pipelines using PyTorch and OpenAI APIs, and implemented event-driven systems with Kafka and AWS EventBridge to ensure reliable data synchronization and low-latency APIs. At Snowflake, I developed elastic compute scaling, real-time ETL pipelines, and gRPC/Golang services to improve query throughput and system reliability.
I emphasize secure, observable, and cost-efficient cloud operations—automating deployments with Terraform and GitHub Actions, establishing observability with DataDog and Prometheus, and mentoring engineering teams in cloud-native practices, performance optimization, and robust software design.
