Overview

I am a Frontend Engineer with over 5 years of experience in building high-performance web applications.

I have designed and built StoreFront, a comprehensive e-commerce solution, achieving top scores in performance and accessibility on Lighthouse. My approach focuses on delivering clean, maintainable code and ensuring optimal user experiences. I utilize tools like Drizzle ORM, Neon PostgreSQL, and Stripe for seamless integration and functionality. I have successfully delivered projects for clients, including a family-owned winery, where I managed the entire development process from schema design to deployment. I am currently available for new projects and excited to help you bring your ideas to life!
