Featured Projects
Selected work that shows how I approach architecture, delivery, and outcome-driven engineering.
Designed a real-time AWS regulation engine that validates streaming orders, enforces sourcing conditions, and automates compliance decisioning for Milwaukee Tool's US, Canada, and Mexico trade operations — replacing a manual compliance review process.
Designed and implemented Meta's global trade management platform spanning product classification, restricted-party screening, trade-document generation, and carrier/DC onboarding across APAC and North America — establishing compliance workflows and exception-visibility tooling from the ground up.
Redesigned lululemon's shipping, rating, address-validation, and routing API platform for high-throughput guest-order fulfillment across 7 distribution centers and 500+ stores — reducing AWS spend by 60% and integrating 5 parcel carriers under standardized onboarding patterns.
From the Lab
Open-source tools built for Oracle OTM, EDI, parcel shipping, and supply chain teams — scratching itches that commercial platforms don't.
EDI Explainer
AI-powered X12 EDI message analyzer for logistics and transportation teams. Paste a 204, 210, 214, or 990 payload and get row-level segment breakdowns with context, field definitions, and confidence scores. Includes a document ingestion pipeline for implementation guides and a persistent correction store to improve future explanations.
otmOS
A consolidated web workspace for Oracle Transportation Management teams — replacing the usual sprawl of spreadsheets, static docs, and one-off scripts. Includes XML/JSON validation, XPath/JSONPath generation, payload inspection, a data dictionary and schema browser, SQL builder with relationship guidance, and QA test cycle management.
ReleaseDataGen
Streamlit app that generates and posts Oracle OTM Order Release XML payloads for dev and test environments. Supports manual entry, CSV/Excel import, and randomized test-data generation. Built-in safeguards block posting to production endpoints. Outputs individual XML files or ZIP batches.
