Project Summary
Infinity is a configurable work management system designed to allow users to model their own workflows rather than conform to predefined structures.
At its core, the platform supports dynamic entities (boards, folders, items), custom attributes per object, multiple data views (table, columns, calendar, list), flexible permission modeling, and cross-workspace collaboration.
The primary architectural challenge was enabling high flexibility while maintaining predictable performance and tenant isolation.
The system is built as a multi-tenant SaaS application with strict logical tenant separation, ensuring workspace-level isolation across data access, permissions, and background processing.
🧠 Engineering Highlights
- Modular Data Modeling: designed a flexible data abstraction layer allowing users to define custom attributes and object relationships without breaking query performance. Balanced schema flexibility with relational integrity to prevent unbounded complexity and query degradation.
- Multi-Tenant Architecture: implemented logical tenant isolation across database access, background jobs, permission enforcement, and caching layers. Ensured workspace-level separation while maintaining shared infrastructure efficiency.
- View Engine & State Management: built a multi-view system (table, kanban, calendar, list) powered by a shared data model. View rendering is decoupled from storage structure so the same dataset can be projected in multiple formats without duplication. State synchronization logic ensures consistent behavior under concurrent updates.
- Permission & Collaboration Model: designed granular permission layers across workspace, folder, board, and item. Ensured deterministic access control evaluation to prevent cross-tenant leakage and unauthorized visibility.
