01 / Problem
A fragmented workflow slowed the whole system.
Teams needed one product for visually modeling workflow logic and database relationships while also managing collaboration, access, usage plans, and mobile authentication. Dense diagrams had to remain understandable and responsive during active editing.
02 / Solution
One product model, expressed clearly at every layer.
I developed the public website, client portal, Vue Flow node editor, ERD modeling interface, TeamHub workflows, subscription screens, and companion mobile key application. Shared state and reusable components connect these surfaces into one product experience.

Active layer 1
Public Nestflow website
Public Nestflow website owns the user-facing workflow and consumes a stable contract.
Responsibility stays explicit at this boundary.
Decision log
Separate graph data from rendered node state
- Context
- Dense diagrams could trigger unnecessary component updates while dragging
- Decision
- Normalized graph state and limited updates to affected nodes
- Trade-off
- Increased state-model complexity but improved interaction stability
Decision log
Reuse product concepts across web and mobile
- Context
- Authentication and account state needed to remain familiar across multiple surfaces
- Decision
- Shared workflow terminology and aligned interface states between the portal and mobile key application
- Trade-off
- Required cross-platform coordination but improved product consistency
03 / Challenges overcome
Complexity moved behind durable boundaries.
Dense node and ERD diagrams can produce expensive reactive updates during dragging, selection, connection, and zoom operations. The implementation needed to control rendering work while maintaining synchronized product state across portal and mobile experiences.
