User Experience

Role-based dashboards for landlords and tenants with tailored views for payment summaries, lease details, and communication threads.

Key Engineering Challenges

Payment Processing

Challenge: Handling complex payment scenarios including partial payments, late fees, and security deposits.

Solution: Built flexible payment engine using Stripe's Payment Intents API with idempotency keys, webhook handling for async updates, and transaction ledger system for reconciliation.

Multi-Tenancy Architecture

Challenge: Isolating data between property managers while enabling tenant portal access across properties.

Solution: Implemented row-level security with Prisma, role-based access control (RBAC), and organization hierarchy supporting unlimited properties per manager.

Document Management

Challenge: Securely storing and managing leases, contracts, and sensitive tenant documents.

Solution: Integrated AWS S3 with pre-signed URLs for secure uploads/downloads, document versioning, and encryption at rest. Added e-signature integration via DocuSign API.

Solutions Implemented

  • Automated Rent Collection: Set up recurring payments with automatic retry logic, late fee assessment, and multi-channel payment reminders reducing late payments by 70%.
  • Maintenance Management: Tenant portal for submitting requests with photo uploads, automatic vendor assignment, progress tracking, and completion verification.
  • Lease Management: Digital lease creation with customizable templates, e-signature workflow, automatic renewal reminders, and centralized document storage.
  • Financial Dashboard: Real-time revenue tracking, expense categorization, profit/loss statements, tax-ready reports, and automated 1099 generation for vendors.
  • Tenant Screening: Integrated background checks, credit reports, rental history verification, and automated score-based approval recommendations.
