Property Management System
An end-to-end property management platform handling the full lifecycle from tenant onboarding to financial reporting.
Key Engineering Achievements
The engineering decisions and challenges behind this project
Enterprise Modular Architecture (NestJS)
Property management involves deeply interconnected domains — tenants, leases, payments, and maintenance all reference each other.
Leveraged NestJS's module system to create bounded contexts for each domain with well-defined interfaces between them. Used dependency injection for testability.
Clean domain boundaries that allow each module to evolve independently while maintaining referential integrity.
Document Management with AWS S3
Securely storing and retrieving lease agreements, tenant documents, and maintenance photos.
Implemented pre-signed URL uploads direct to S3, with server-side validation, virus scanning hooks, and automatic thumbnail generation for image documents.
Secure document handling with no server-side file storage overhead and instant retrieval.
Automated Financial Reporting
Landlords need real-time visibility into revenue, arrears, and property performance.
Built a reporting engine that auto-generates financial summaries, occupancy rates, and maintenance cost breakdowns with exportable PDF reports.
Landlords get actionable financial insights without manual spreadsheet work.

Developer's Note
“This project pushed me into enterprise patterns — NestJS's opinionated structure was initially constraining, but it forced clean architecture that pays off as the codebase grows. The biggest challenge was modeling lease states (active, expired, renewed) correctly.”
