// EXPERTISE
What I do
Frontend Architecture
Building scalable frontend systems from design tokens to deployment — Angular, React, Vue, and Next.js. Deep knowledge of component design, performance, and state management at scale.
Design Systems & Libraries
Creating custom component libraries and npm packages teams actually want to use. Storybook-documented, typed, tested — turning design decisions into reusable, consistent systems.
Team Leadership
Growing engineering teams through mentoring, code reviews, and personalized growth plans. Experience in hiring, onboarding, and aligning team efforts with product goals.
DevOps & Tooling
CI/CD pipelines on GitLab, GitHub Actions, and Azure DevOps. Infrastructure on Azure. Semantic release, automated quality gates, and developer experience tooling.
