I was the primary developer behind the software that runs an ultra-high-temperature (UHT) dairy manufacturing operation — top contributor across the platform's repos, and the person the plant called when something needed to work.

The platform

• Built and owned the applications the plant runs on — Vue 3 progressive web apps (PWAs) for work orders, inventory and pallet management, receiving, quality control (QC) sampling and release, bin transfers, and fulfillment — used daily by ~95% of active staff across warehouse, quality assurance (QA), packaging, production, and management. I wrote 80%+ of the frontend.
• Built real-time features with Socket.IO: production key performance indicator (KPI) dashboards on shop-floor TVs, a live line-staging dashboard, and escalating material-low and queue alerts to operators and Microsoft Teams.

Manufacturing execution system — MES

• Sole author of an MES service that bridges the plant floor and the enterprise resource planning (ERP) system: scheduled pollers read real-time process data from the plant's supervisory control and data acquisition (SCADA) historian, per-tank state machines reconstruct production batches at every stage of the line, and the service posts the matching NetSuite transactions automatically — receipts, assembly unbuilds, work order create/issue/complete, waste adjustments, and reconciliation sweeps.
• Engineered it to run unattended: restart-safe state recovery from SQL Server, idempotent retries that never double-post, a review queue for unrecognized products, a dry-run sandbox mode, and Teams alerting.
• Millions of pounds of milk a week land in NetSuite fully lot-traceable and costed, with zero operator data entry — in-plant production that previously wasn't recorded in the ERP at all.
• Built the automated backflush and consumption system that raised contemporaneous production tracking from ~20% to 95%, and eliminated lost inventory updates by serializing concurrent pallet consumption with per-bin, per-work-order locks.
• Full architecture write-up: the MES case study.

Integrations & architecture

• Split a monolithic Express API into independently deployed services — gateway, manufacturing, MES, ERP, and printing — each with GitHub Actions CI/CD for dev and production, mapping upstream and downstream dependencies to cut deployment risk.
• Designed, documented, and supported RESTful workflows and secure OAuth 1.0a NetSuite integrations for work orders, item receipts, fulfillments, inventory adjustments, QC release, bin transfers, and lot traceability — my services posted over 90% of the company's ERP transaction lines automatically (1.4M+ lines company-wide in the first seven months of 2026).
• Replaced major RF-SMART warehouse and inventory workflows with custom barcode-driven software, eliminating roughly $250K/year in third-party licensing.
• Co-built the application programming interface (API) gateway that fronts every client app on the platform — authentication and brokered access to NetSuite and Active Directory.
• Built the company's external web portal: a Vue 3 frontend behind a hardened Express gateway with JSON Web Token (JWT) access/refresh auth and curated data transfer objects (DTOs), running on Node 22 with PM2 and Caddy — including a milk-diversion planner that forecasts silo capacity and recommends daily truck diversions.

Reliability & people

• End-to-end testing, production troubleshooting, root-cause analysis, and change-impact validation across every application the plant depended on.
• Primary support resource and subject-matter expert for the platform; partnered with warehouse, QA, production, procurement, accounting, and management to turn business needs into shipped software.

• Fulfilled online pickup and delivery orders in a fast-paced, metrics-driven environment while maintaining accuracy and service standards.
• Trusted subject-matter expert for department workflows; routinely assigned complex tasks based on reliability and operational knowledge.
