From incoming rates to a quote someone can review
At DNA Supply Chain Solutions, I built logistics quoting and rate-ingestion workflows in Mastery. My work connects incoming rate data, background processing, and the steps an operator uses to prepare a quote. As of October 2026, I estimate that approximately 30 employees use Mastery.
These workflows need more than a successful first run. A worker can stop partway through processing. A user can retry an action. A quote request can arrive while another attempt is still in progress. I worked on making those states explicit and recoverable.
This depends on stop-first replacement: the old and new consumers must not overlap under the same identity.
Recover abandoned work without ignoring active work
An interrupted ingestion job could remain locked until its timeout. I changed both job selection and the conditional claim to recognize work left by a stopped predecessor, so a replacement can recover it immediately. Queue contract tests cover reclaiming that work while preserving the timeout boundary for other workers.
Quote generation has a separate conflict problem. I added a transaction that locks the selected quote option, checks the requesting recovery session, and reserves the option before generation. A different recent active session is rejected. Tests cover successful reservation and rollback on a conflict; this protects the start of generation rather than promising exactly-once downstream effects.
Scale of the quoting workflow
A review of retained database records for July–September 2026 found 1,064 newly recorded quote numbers after known test and deleted-record exclusions: roughly 350 per month. The count uses the first appearance of each normalized quote number, rather than counting every saved version.
Production/test isolation is not fully confirmed. These are recorded quote numbers, not a count of customer-released quotes, bookings, or deliveries.
