I’m a Senior Software Engineer with 14+ years designing and building scalable full-stack apps using C#, Java, and Rust across cloud-based platforms. I focus on reliable systems, strong performance, and collaborative engineering practices—especially mentoring through architecture discussions and code reviews.

At In-House Realty, I designed and developed a cloud-based SaaS platform using C# (.NET Core), ASP.NET MVC, and SQL Server, supporting workflow automation and data processing across 32 internal services. I built scalable backend services with .NET Core Web API and Java Spring Boot microservices, processing 12M+ records daily across distributed services.

I’ve integrated AI-driven processing into production workflows by implementing an AI-assisted document and data classification service using Python ML pipelines in combination with C# services, improving categorization accuracy by 36%. I also built event-driven ingestion pipelines using Apache Kafka for real-time processing, implemented secure authentication with OAuth2/OpenID Connect/JWT, and developed high-performance background processing utilities in Rust to improve concurrency for compute-intensive workloads.

Across teams, I’ve strengthened delivery quality with automated testing pipelines (xUnit, NUnit, JUnit) and CI validation, and I’ve deployed containerized services using Docker and Kubernetes on AWS and Azure. Earlier roles included building analytics services at Quicken Loans and operational applications at Marathon Petroleum, and I bring that same systems mindset to mentoring interns and supporting data-heavy analytics.
