Budding Software Engineer | Full-Stack Development Aficionado in Training

Greater Seattle Area

I'm a full-stack developer specializing in .NET (C#), React, and TypeScript. My focus is on building efficient APIs, modernizing front-end architectures, and creating scalable web solutions. I'm big on performance and user experience. I've set up CI/CD pipelines with GitHub Actions and Azure, and I've dabbled in Android development using Java, Kotlin, and Jetpack Compose. Always keen to tackle new challenges and learn emerging tech.
