What I'm looking for

I'm looking to build scalable, high-performance products where I can own frontend systems end-to-end, collaborate across the stack, apply AI and automation, and create polished, maintainable user experiences.

I build scalable, user-centered web applications across CSG, Tropical Year, Retailogists, and Applica Corp, with a strong focus on React, Next.js, TypeScript, clean architecture, and production-ready interfaces.

At Applica Corp, I led frontend architecture and Atomic Design adoption, achieving approximately 40% component reuse. I also optimized Vercel CI/CD pipelines, reducing deployment time by approximately 70%.

At Tropical Year, I shipped MyZoning.ai, Split Squid, CMS-driven marketing experiences, and a Lighthouse audit platform. My work spans Next.js, React Native, Supabase, Sanity CMS, mapping tools, authentication, analytics, and payment integrations.

I also build AI-driven systems with Python, machine learning, LLMs, cloud services, and automation workflows at CSG. Alongside engineering, I’ve led software engineering instruction and mentored developers through hands-on projects and production practices.
