Reporting work rooted in how transactions actually move
DataStream Apps is a Busan-based practice focused on event-driven application reporting for transaction flows and interaction patterns. We sit with the people who own the desk, write definitions they can defend, and leave packs that survive after we leave.
Origin
The practice started after repeated projects where weekly numbers disagreed with cash offices, support queues, and floor supervisors. The gap was rarely “missing charts.” It was unsettled event names, duplicated checkpoints, and reports written for an audience that never saw the path.
Working from 128-7,Myeongryun-dongDongrae-guBusanKorea, we keep engagements close to Korea-based teams while supporting remote workshops for distributed stakeholders.
How we work
We prefer concrete flow inventories over abstract maturity talks. A typical engagement begins with a short scope conversation, continues with mapping sessions, and ends only when two reporting cycles hold steady and a handoff guide has been used once by your staff.
We do not sell hosting, product licenses, or real-time alerting builds. When retainers continue after handoff, they cover production of an agreed pack—not open-ended product development.
Values we hold in the room
- Definitions before decoration—names and owners first, visuals second.
- Exceptions written in plain language so nobody pretends the path is cleaner than it is.
- Handoff as a real deliverable, not a courtesy PDF.
- Respect for the vocabulary already used on the floor in Busan and across Korea.
