Solving engineering challenges for productivity web apps that resolve challenges for distributed teams and require fine-tuned relational data integrity, RBAC or PBAC, timezone-stability, real-time collaboration, reports and forecasts
Productivity features can be the core of a product or a layer on top of an existing one. Either way, a few patterns tend to signal strong fit: work has dependencies that need to be visualised over time, multiple people need different levels of visibility into the same tasks, time needs to be tracked against work items for billing or resource planning, or teams are coordinating across timezones and need a shared source of truth. When structure and accountability become product requirements, the data model underneath them matters.
This service covers Kanban and Gantt data models, RBAC/PBAC permission systems, timezone-accurate date arithmetic, real-time collaborative editing with conflict resolution, and reporting aggregations. Core focus is on relational data integrity across task hierarchies, optimistic UI patterns that stay consistent under concurrent edits, and event architectures that scale with organisational complexity.
Productivity tools are deceptively complex to build well. Each major feature carries its own set of engineering challenges that only become visible once real users stress-test the product.
| Feature | Technical Challenge | What I deliver |
|---|---|---|
| Kanban Board | Drag-and-drop reordering, real-time card sync, lane management | Optimistic UI, WebSocket sync, customisable workflows |
| Gantt Chart | Date arithmetic, dependency graph, critical path calculation | Interactive timeline, task linking, milestone tracking |
| Time Tracking | Timer accuracy, timezone handling, reporting aggregations | Background timers, exportable reports, team dashboards |
| Real-time Collaboration | Conflict resolution, presence indicators, activity feeds | Live cursors, change history, graceful conflict handling |
