About

Senior Frontend Engineer with 8+ years of experience building production-grade, state-heavy web applications. I specialize in designing and implementing complex frontend systems using React and Next.js, with a strong focus on product thinking, UX quality, and reliability. I’ve worked closely with product, design, and backend teams to turn ambiguous requirements into clear, scalable frontend architectures that ship to production. Experienced working fully remotely with international teams across the US, Europe, and LATAM.
