Practical notes from the field.
Promo spikes break manual WMS imports—inventory and shipment status drift while support says “system delay.” Five practical checkpoints before API sync goes live in warehouse and e-commerce integration: inventory authority, state machines, and exception reconciliation.
Vendor gone, docs thin, jobs that only one server “knows how to run”—when taking over .NET legacy systems, the costly mistake is changing code before you understand production. Seven checks we complete before maintenance work on bank conversion, subsidy disclosure, and enterprise back-office projects.
Assignment slots checked by hand, reports and expenses handled separately, annual KPIs in spreadsheets—when field ops and performance live in silos, leaders cannot answer quarterly support outcomes. Six practical checkpoints from cross-border assignment and HR KPI work to connect dispatch operations metrics.
Deadline crunch, manual Excel exports, missed uploads—hand-built subsidy disclosure invites rejections and delays. Five practical checkpoints from similar nonprofit and public-sector work before API scheduling, with views for decision-makers and engineers.
Legacy ERP cannot be replaced overnight—dual writes and fuzzy boundaries surface failures at peak load. Five practical rules from manufacturing rollouts: wrap legacy ERP with .NET, avoid dual writes, define system boundaries, and reduce coupling with event-driven integration.
Mobile banking must pass KYC, 2FA, and compliance review—long onboarding flows leave users stuck after verification failures. Three design trade-offs we use under regulatory constraints: resumable checkpoints, actionable error feedback, and early legal involvement in UX decisions.
