Senior Full-Stack & Systems Engineer • 11+ Years Experience

Hello World, I'm

Kevin Patel.

I build enterprise .NET Applications & Scalable Platforms.

11+ years of experience architecting full-stack applications from .NET Framework legacy migrations to cutting-edge .NET 10 / C#, reactive Angular (v4–12+) & AngularJS SPAs, high-throughput RabbitMQ distributed queuing, and enterprise MS SQL / PostgreSQL / BigQuery data pipelines.

// WHO I AM

11+ Years of Full-Stack & Systems Mastery

Deep expertise building high-performance architectures, enterprise SPAs, and distributed messaging pipelines.

I am a Senior Software Engineer with over 11 years of hands-on experience engineering scalable web applications, robust backend microservices, and reactive frontend platforms.

My background encompasses the complete lifecycle of modern web engineering: architecting enterprise backends across C# and .NET (from legacy .NET Framework through .NET Core, .NET 6/8, to .NET 10), building rich responsive SPAs with Angular (v4 to v12+), AngularJS, TypeScript, and Blazor Server, and managing high-capacity relational and big data warehouses (MS SQL Server, PostgreSQL, Google BigQuery).

In distributed systems, I specialize in RabbitMQ messaging architectures, implementing delayed message exchanges (x-delayed-message), concurrent consumer worker pools, dead-letter routing, and zero-loss transactional outbox patterns across mission-critical domains.
