Selected systems I own or ship on
RecurringDataFeeds (RDF)
Sole architectPython/Prefect 3 ETL platform on Kubernetes spanning SQL Server, Oracle, MongoDB, Databricks, Db2/Cosmos, and S3. Replaces a legacy SSIS package with 60+ sequence containers, 300+ SQL tasks, and 120+ data flows, and consolidates a 380+ report SAS estate. Claims feeds built end to end: automated claim routing, reversal logic, AUS work-item queueing, and downstream persistence.
$100K+/yr recurring savings today with a path to several hundred $K/yr; $3M+ projected claim-payout impact for Medicare & Retirement adjudication.
QRT
Primary engineerHybrid Express + Next.js platform for claims search, audit creation, and review over SQL Server, Hive, and MongoDB. 900+ commits across the stack — from query layers to review workflows.
Core day-to-day tooling for claims audit and review teams.
DataOnDemand
Lead engineerNext.js self-service report catalog. Migrated report metadata from SQL Server to MongoDB and executes read-only reports across 7+ engines: SQL Server, Db2/Cosmos, Oracle, Snowflake, and Databricks.
Self-service reporting across 7+ database engines from one catalog.
Fastbase + DOC360
ContributorReact/Next + Node/MongoDB app replacing Excel/OneNote workflows. Built the DOC360 document feed in RDF to retrieve and email documents automatically.
Retired manual spreadsheet/OneNote workflows; automated document retrieval and delivery.
Platform & delivery ownership
Owned the platform layer across projects: SSO/OIDC reverse proxy, Kubernetes work pools and network policies, CI/CD with Artifactory + Vault, digest-pinned rollouts, and HIPAA/HITRUST/PHI/PII controls on Azure and GCP.
How I work
I turn manual, license-heavy, and legacy processes into automated systems that pay for themselves.
I started in process automation at Optum — $572K capital and $210K annual recurring savings in my first year of coding — and now architect AI-integrated claims solutions at UnitedHealthcare with $3M+ in projected claim-payout impact. I design, build, and ship end to end: Python/Prefect data pipelines, Next.js and Node services, and Kubernetes delivery, while juggling five production codebases in parallel.
My focus is simple: solve the real business problem, retire expensive legacy tooling, and make the impact measurable.

Get in touch
If you have a legacy process that should be an automated system, or a platform problem that needs an owner, I'd like to hear about it. LinkedIn is the best way to reach me.
