What I'm looking for

I seek roles building production data platforms and LLM/AI systems in collaborative, engineering-driven teams where I can scale pipelines, improve automation, and deliver measurable business impact.

I am a data engineer and AI-focused software engineer experienced in building scalable ETL/ELT pipelines, cloud-native data platforms, and production LLM workflows. I design and implement data models, automated validation frameworks, and streaming solutions to support analytics and operational use cases.

At TEKsystems I implemented RAG-based policy engines, multi-agent LangGraph workflows, and document-processing pipelines that automated underwriting, processed 10,000+ medical PDFs, and reduced manual processing and backlog substantially. I also migrated millions of HR records, designed 30+ normalized data models, and saved significant remediation costs.

I work across AWS, Snowflake, Apache Spark, Kafka, and cloud/serverless services, and I prioritize reliability, observability, and cost-effective architectures that scale. I seek roles where I can drive data strategy, productionize ML/AI solutions, and mentor cross-functional teams.
