About

Kumar Abhishek
Full-Stack Developer

Full-Stack Software Developer with 2+ years of experience specializing in rapid e-commerce development, SaaS platforms, and email marketing solutions. I have a proven track record of delivering complex projects under tight deadlines, including complete platform rebuilds in 1-2 weeks.

I'm an expert in the Next.js/React ecosystem with extensive experience in Shopify integrations, multi-tenant architecture, and cross-client email development. I've successfully led projects from conception to deployment, serving as the sole developer on multiple revenue-generating platforms.

At Xamtac Consulting, I've built everything from multi-vendor e-commerce platforms processing 100+ daily transactions to large-scale SaaS applications supporting 500+ concurrent users. I thrive in fast-paced environments where tight deadlines and high standards meet.
