Message

At Virtual Commerce Ventures LLC, I designed and built an operational marketplace integrating payment, email, AI, and third-party services. I also architected an AI-powered card grading platform using Azure AI Foundry, retrieval-augmented generation, image analysis, and historical grading data.

At ExxonMobil, I architected ETL solutions with Azure Data Factory, Azure Functions, and Microsoft Fabric to ingest, standardize, and deliver business-critical datasets. I integrated governed operational data with a secure, context-aware retrieval-augmented generation architecture.

At Sophos Med Solutions LLC, I engineered a multi-tenant Azure EMR platform aligned with HL7 and FHIR standards. Across my .NET work, I’ve also modernized applications, developed APIs and full-stack products, and worked with healthcare, cloud data, and AI-enabled systems.
