Resourceful front-end developer who builds responsive React experiences and iterates fast.
United StatesWhat I'm looking for
I’m a resourceful front-end developer with a proven ability to learn quickly and adapt in fast-paced environments. I enjoy collaborating with designers and developers to deliver polished, user-focused web applications.
In my internship on the Ultraverse NFT Trading Platform, I integrated workflow and communication across a cross-functional team. I engineered a responsive carousel component to improve product discovery, built a dynamic NFT feature page that adapts to each author’s portfolio, and refactored code to improve site performance by 11%.
More recently as a Junior Software Developer, I developed and tested features for AI-driven applications, troubleshooting and debugging alongside teammates to improve stability and performance. I deployed applications to Vercel and maintained a 99.9% uptime standard, then implemented new features using HTML, CSS, JavaScript, & PHP to increase user engagement.
I’m passionate about solving problems and committed to continuous growth in coding and design. I’m currently pursuing a FES Institute Certified Front-End developer program, and I consistently push myself to master new concepts, embrace challenges, and ship better user experiences.
