What I'm looking for

I'm looking to lead architecture and engineering work on scalable data platforms, real-time streaming, distributed systems, and agentic AI solutions with measurable business impact.

At Realogy, I led Kafka-Debezium real-time CDC ingestion, Spark ETL frameworks, and Scala-based compaction on AWS. My open-source data integration work with Debezium and DLT delivered $2.5M in annual savings, while Spark and Glue optimization improved job performance by more than 300%.

I've built distributed reporting, streaming, and data platforms across Realogy, Capital One, Freestar, SpotX, and Microsoft. I also build agentic AI solutions using Azure AI Foundry, Azure OpenAI, Azure AI Search, MCP, and evaluation frameworks, grounded in Scala, functional programming, and enterprise data architecture.
