What I'm looking for

I'm looking to lead and build production-ready cloud platforms and distributed systems, applying Java, AWS, data, search, and AI capabilities while mentoring teams and improving engineering quality.

At Intuit, I build Java services for the Persistence Service data lake and search platforms, including governance workflows, metadata APIs for GenAI agents, semantic search, and high-scale OpenSearch ingestion.

Previously at Veeva Systems, I led optimization of a Spring Boot ETL platform for analytical data stores, moved processing to asynchronous AWS SQS workflows, automated AWS and Kubernetes deployments, and mentored engineers on design patterns and testing. At Logic20/20, I developed T-Mobile messaging microservices, led Kubernetes migrations, and built conversational AI solutions with Rasa and AWS SageMaker.

Across 15+ years in enterprise software, I’ve delivered scalable Java APIs, web applications, distributed systems, cloud infrastructure, and production migrations while helping teams improve quality, security, and delivery practices.
