  • Developed the Catalog Builder module for the EYJA Agent Portal, a high-performance SaaS platform enabling homebuilders, brokerages, and clients to create interactive, data-driven digital property catalogs.
  • Designed and deployed a robust, modular backend utilizing Golang (Go) for microservices, managed with the Gorilla Mux router, ensuring extreme concurrency and low latency for real-time catalog editing.
  • Implemented a WebSocket Hub to handle real-time, bidirectional communication, enabling instant updates for collaborative editing and live preview without requiring manual page reloads.
  • Integrated Single Sign-On (SSO) capabilities using OAuth 2.0standards. Comprehensive Unit Tests verified the end-to-end authentication flow and token exchange.
  • Implemented RESTful APIs using Golang and the Gin/Mux framework for catalog creation, template management, and publishing workflows, emphasizing resource efficiency.
  • Used PostgreSQL as the primary data store, focusing on schema optimization, indexing, and connection pooling to efficiently handle thousands of concurrent user requests.
  • Leveraged Amazon S3 for the secure and scalable storage of catalog assets (high-resolution images, interactive media). Integration Tests validated secure file management and access controls.
  • Implemented Redis for application-level caching of frequently accessed catalog metadata and configurations, significantly reducing database query load and enhancing API response times.
  • Implemented sophisticated Role-Based Access Control (RBAC) and transactional versioning logic.
  • Containerized all Golang microservices using Docker for consistent deployments. Implemented centralized logging by streaming application and access logs to MongoDB for rapid operational analysis.
