## What I'm looking for

```text
I want to architect and ship cloud-native .NET microservices on Azure, with strong DDD/Clean Architecture, CI/CD, and observability—while mentoring teams to deliver secure, resilient systems that scale.
```

## About

```text
I’m a Senior .NET Software Engineer & Architect with 12 years of experience designing and delivering high-performance, cloud-native web applications. I architect scalable solutions on the Azure platform using .NET 7+, Entity Framework Core, and microservices architecture to support maintainability and rapid, reliable deployment.

I excel at establishing robust engineering practices—CI/CD pipelines via Azure DevOps, Domain-Driven Design (DDD), and clean code principles—so systems stay resilient and easy to evolve. At Big Health, I adopted DDD and Clean Architecture, optimized REST APIs, and led CQRS and event-driven patterns with MediatR and Azure Service Bus; this work improved code maintainability and scalability by 40% while enabling real-time patient data processing.

I focus heavily on delivery quality and operational excellence. I integrated Serilog, Application Insights, and Azure Monitor to track performance and detect anomalies, reducing MTTR by 30%, and used tools like dotTrace and SQL Profiler to cut response times by 25% during high-traffic periods. I also enhanced security and compliance with RBAC, MFA, and OAuth2 to align with HIPAA requirements.

Across my roles—from KeyBank to Cashdrop Inc—I’ve built systems that scale and modernize legacy platforms. I’ve automated deployments (e.g., reducing deployment time by 60%), containerized services with Docker and AKS, and delivered end-to-end solutions ranging from healthcare portals to e-commerce microservices.
