## About

```text
At Robotic Assistance Devices (RAD), I lead backend engineering for SaaS security products, setting coding standards, reviewing .NET code, mentoring engineers, and planning work across Agile sprints. I designed and delivered SARA Connect through the full SDLC, including camera integration, response workflows, SMS-to-voice escalation, and a real-time operator dashboard.

For RAD’s Sentinel platform, I build and maintain high-traffic ASP.NET Core (.NET 8) APIs with subscription-based rate limits and quotas. I scaled a WebSocket service to 100 concurrent camera streams and implemented distributed caching and locking to coordinate background workers across server instances.

I also work on the RAD SOC Dashboard, whose MongoDB and Elasticsearch pipelines ingest detections every five seconds. I run Docker and Bitbucket Pipelines deployments to AWS ECS, including blue/green releases and automated rollback, as well as deployments to Azure Container Apps and Blob Storage.

Previously, I architected inventory, supply chain, and production modules at Dehlawi Optical Industries, and built ERP and SaaS products at Invision Custom Solutions Inc., Masterkey, and iSplendid. Across these roles, I worked with .NET, SQL Server, microservices, and cloud deployments, and integrated AI services and third-party APIs into RAD products.
