About me
I build Shopify stores and business software that help small and growing businesses run more efficiently.
Over 4+ years as a full-stack developer, I've built custom Shopify stores for retail brands, a POS and inventory platform used daily by clothing retailers, and GoHighLevel integrations for agencies. Stack: React, Next.js, Node.js, SQL/NoSQL.
I build things that work in production, not demos: real orders, real dashboards, real APIs. Clean code, clear communication, on-time delivery.
Need a dependable developer for e-commerce or business software? Let's talk.
