• Built an end-to-end remote DNS configuration feature across a cloud management platform, embedded NAS devices, and Linux-based recording devices — enabling operators to manage upstream DNS servers across customer deployments without on-site access.
• Engineered GitHub Actions CI/CD pipelines to automate build testing, package deployment to a Nexus artifact repository, and application bundling, reducing manual steps in the release process.

• Developed and launched a React Native iOS application as the sole developer, growing to 1,000+ users and winning the $1,000 “Best Real World Impact” award at the Canadian Tech Summit.
• Reduced profile load times from 1.4s to 100ms using indexed JPQL queries, AWS S3 presigned URLs, and automated WebP image compression.
• Deployed containerized services with Docker, implementing real-time WebSocket messaging (STOMP, Redis pub/sub) with push-notification fallback, AES-GCM encryption, and async non-blocking processing.

• Reduced API response latency by 45% for 10,000+ active users through Redis caching, endpoint refactoring, and PostgreSQL query optimization with proper indexing strategies.
• Accelerated developer onboarding by 20% by authoring comprehensive Swagger/OpenAPI documentation and interactive Postman collections for 30+ RESTful endpoints.
• Architected and implemented 8 new backend features in NestJS following SOLID principles, dependency injection, and test-driven development.
