I build production frontend systems,
working across interface development, UX/UI, testing, and deployment.
Experience
& Expertise
How I Work
I work from early concepts through implementation, testing, and release, connecting interface development with the technical decisions behind it.
I adapt to the existing product and codebase, focusing on clear interfaces, maintainable code, and practical ways to test and deliver changes.
Capabilities
Frontend Development & Architecture
I build applications, structure frontend code, and develop shared component libraries.
Testing, CI/CD & Deployment
I use Playwright tests, GitHub Actions workflows, preview environments, and cloud deployment pipelines.
UX/UI & Interaction Design
I design interfaces and bring them into code, including responsive layouts, interaction states, and motion.
AI Application Development
I connect AI models with application logic, streaming chat, voice, and backend services.
