Some of my Open Source projects
I've spent over 8 years woking on Web engineering, mostly building features and taking care of architectures for client facing products and enterprise software for public tech companies and Fortune 500 enterprises.
I've been working on open source and non-profit projects too! It brings me so much joy contributing back to the community.
I enjoy building tooling around testing, documentation, and CI/CD to improve developer experience. On top of solid coding and automation, nothing makes me happier than creating a meaningful product with thoughtful user experience and great performance.
