About Me

I’m a software engineer with 3+ years of experience building SDKs, developer tools, and application software across frontend, backend, and systems layers. I’ve worked primarily in Java, C#, and JavaScript, and I enjoy building software that provides real customer value.

At Hewlett Packard, I worked on an SDK team where I developed sample apps and demos (including React apps), built automation and test frameworks, and managed CI/CD pipelines in Azure DevOps. A big part of my work focused on improving developer experience, release reliability, and test coverage. I’ve also contributed to large firmware codebases, which taught me how to work carefully in complex, multi-team systems.

I recently earned the AWS Certified Solutions Architect – Associate certification and am continuing to build my cloud and system design skills. I’ve also been studying neural networks in PyTorch to better understand how modern ML systems are built. I’m motivated by learning, writing maintainable code, and building tools and products that are genuinely useful to others.
