Modernized the systems that connected sales, inventory, service, and fulfillment.

  • Reworked backend logic across inventory, quote, RMA, and fulfillment workflows.
  • Improved checkout, procurement, diagnostic, testing, and data-visibility tools around daily business operations.
  • During a self-initiated evening investigation, traced unusually high AWS usage to idle servers and compute-heavy experimental eBay scraping workloads, identifying a path from roughly $12,000 to $2,500 in monthly spend.

Role and context

Web Developer

Raleigh, NC. Legacy electronic test and instrumentation hardware workflows, November 2025 to May 2026.

A useful investigation beyond the core brief

The cloud-cost result was not the center of the role. In one self-directed evening, I noticed that AWS spending was abnormally high, inspected logs and resource usage, identified servers with little or no activity, and isolated compute-heavy experimental scraping workloads used to track replacement inventory on eBay. That evidence made it possible to separate necessary infrastructure from avoidable spend.
