Coldwell Banker Real Estate Platform
A high-performance real estate discovery platform featuring interactive geospatial mapping, property filtering, and automated lead routing for regional brokerages.
Automated disk garbage collector prunes superseded images on edit/delete
Complete dual-locale Arabic/English schema modeling and dynamic RTL rendering
Node.js REST API Server and React 18 / Vite Interactive Portal
01: Operational Challenge & Concurrency Bottleneck
I architected and built the RESTful API service with file lifecycle management, and the interactive client portal featuring Mapbox views and bilingual interfaces.
High-end real estate portals often suffer from disjointed multi-language search indexes, sluggish property searches, and unmanaged media files accumulating on storage servers during frequent listing updates.
Maintaining cross-entity counts across developers, areas, compounds, and properties while preventing orphaned media files on physical storage during high-frequency multipart updates.
I engineered an automated diffing file cleanup subsystem that captures document state prior to mutation, computes symmetric differences between existing and incoming file arrays, and unlinks superseded assets on storage without blocking requests.
Core Subsystem Modules & Domain Isolation
Automated Orphan File Garbage Collector
Computes array-level symmetric differences on document mutations to eliminate orphaned assets on disk storage.
Multi-Stage Real-Time Aggregator
Executes pipeline stages to compute live top-tier area and property-type rankings on the fly.
Geospatial Coordinate Mapper
Renders hardware-accelerated interactive maps with custom marker injections and viewport centering based on project coordinates.
Bilingual Schema Localization Bridge
Dual-schema field modeling paired with client-side language detectors and automatic CSS directional flips.
Architectural Capabilities & Engineered Workflows
