Backend engineer · three on-site rollouts in logistics
Five years of backend work, the last two embedded with logistics customers: a routing model in production at three depots, an ETL cutover, and an evaluation harness the customer's team still runs without help.
Ran the first-week prototype and the metric definition for two of those deployments, and owned the data-boundary work when the customer refused cloud inference. Comfortable being the only engineer in a room full of operations staff. Looking for delivery work of four to twelve weeks: remote, with up to one week on site per month. Not available for a full-time role before next quarter.
