Digicheck App

Digicheck is an enterprise construction digital-delivery and quality-inspection platform used by multiple contractors on some of Singapore's most iconic projects — including Marina Bay Sands and Marina View Residences, among many others. It replaces paper-based site inspections with digital checklists, multi-level approval workflows and automated reporting for 5,000+ users, and keeps inspection data in sync with Autodesk Construction Cloud (ACC).

Overview

The platform digitises quality assurance and inspection across construction teams — from raising a check, through multi-role sign-off, to automated PDF/CSV reporting. Built as a shared product rather than a one-off, it runs for several firms and dozens of project sites at once while keeping data consistent and tied back to the BIM models in Autodesk Construction Cloud.

Role

Full-stack — React/TypeScript front end, .NET back end, and the serverless ACC integration.

Highlights

Frontend architecture & performance

• Component-based refactor with modern state management (Zustand), cutting user workflow steps by ~50% and noticeably improving the day-to-day experience.
• High-volume, editable data grids (AG Grid) for inspection records, with state patterns that hold up across multiple roles and approval stages.

Backend optimization

• API performance: reduced response times for complex operations from 30,000ms+ down to ~500ms (98%+ faster) through query tuning and database indexing.
• Clean architecture: refactored backend services into clear layers (repository pattern) on .NET / EF Core / PostgreSQL for maintainability and testability.
• Asynchronous processing: a background-worker pipeline handling 1,000+ concurrent operations per sync, offloading heavy work and eliminating API timeouts.

Autodesk Construction Cloud (ACC) sync

• Designed and owned a serverless pipeline (AWS Lambda + EventBridge Scheduler + SQS) that syncs inspection data into Autodesk Construction Cloud, with retry and error handling for reliable, replayable delivery across distributed services.

Outcome

• 5,000+ users across multiple firms and project sites.
• Deployed on iconic Singapore projects — Marina Bay Sands, Marina View Residences, and more.
• 98%+ faster critical APIs and ~50% fewer workflow steps, with automated PDF/CSV reporting replacing manual paperwork.
