I build full-stack web applications and APIs with .NET, JavaScript, cloud services, and AI-assisted engineering.

What I'm looking for

I'm seeking new challenges in modern web development and AI-assisted engineering, with opportunities for personal and professional growth.

At Harris Computer, I build and maintain Angular and .NET systems, including secure OAuth token flows for CRM integrations and SQS-triggered AWS Lambda functions that process message batches asynchronously.

I've used AI-assisted development tools to build, test, and refactor code across Angular frontends and .NET backends, and mapped unfamiliar codebases into queryable knowledge graphs to accelerate onboarding and impact analysis. I also participated in AWS's AI Development Life Cycle workshop in Toronto.

Previously at Harris Computer, I designed customer solutions across Angular, APIs, gRPC, .NET, C#, and SQL Server; migrated APIs and libraries from .NET 4.7.2 to .NET 8; converted WCF services to gRPC; and built a full-stack Q&A proof of concept using OpenAI APIs.

At Growth Acceleration Partners, I delivered frontend and backend features across React, Vue.js, .NET Core, Entity Framework, SQL, NoSQL, and AWS Lambda. I'm passionate about modern web development and AI-assisted engineering, and I'm seeking new challenges that support personal and professional growth.
