What I'm looking for

I'm looking to build and modernize scalable data platforms, improve database performance and reliability, and collaborate with cross-functional teams while mentoring engineers and shaping data architecture.

At BlackLine, I lead architectural decisions for core data platform components, optimizing SQL Server systems and building scalable data models, pipelines, and orchestration.

I've modernized legacy ETL workflows, standardized synchronization and transformation patterns, and improved transactional and analytical data exchange across SQL Server and MongoDB. I also drive query tuning, indexing, workload analysis, testing, and troubleshooting to improve reliability, observability, and performance.

Previously at DealerSocket, I architected SaaS data solutions, advanced data models, synchronization workflows, and modernization strategies for legacy pipelines. My work supported large-scale operations, stronger data interoperability, and more reliable warehouse availability for decision-making.

I enjoy mentoring engineers, conducting code reviews, and collaborating with product, analytics, application, and QA teams to turn requirements into durable data systems.
