5+ Years engineering business systems where Floorplans, Reports, Workflows, and Field Teams need to operate as one reliable product.
Career systems
The common thread is not one stack. It is taking scattered business activity and making it visible, trackable, and easier to act on.
Featured work prototype
DMMS is framed here as a product surface, not a bullet list: a connected operations board for spatial decisions, automation, field work, and business pipeline visibility.
Floorplan mapping, occupancy states, revenue overlays, category filters, and event booking come together as one decision surface.
Branch-specific templates, submission tracking, validation, consolidation, and custom reports replace manual Excel-heavy coordination.
Task assignment, SLA follow-up, check-ins, tour notes, survey forms, and photo metadata create an auditable operational trail.
Lead states, assignment, follow-up tracking, and LINE OA bot reminders give teams visibility from first interest to next action.
Referral tracking wired into LINE OA, watching how invites spread and which ones convert.
LINE OA · attribution
A visual stall map paired with a booking calendar, so availability updates the moment a stall changes hands.

Spreadsheet-backed order tooling with a scannable QR menu that keeps operators moving through service.

Prototype Lab
Three product explorations turned into runnable interfaces: empeo Performance Results tries a 360° review as a manager decision report, ThaiMart pokes at marketplace leverage, and EduSight watches how students write code to spot where they get stuck.
An attempt to turn a 360° review into a manager decision report: weighted self, manager, peer, and org scores become gap flags, a trend read, and merit, bonus, and promotion suggestions for one employee.
A PM-style prototype set that starts from business leverage, then turns each opportunity into a runnable interface with user flows, metrics, and system logic.
A behavior-diagnostic prototype for coding classes: capture IDE-like learning signals, detect support moments, and show progress inside one unified diagnostic experience.
