What I'm looking for

I'm looking to build end-to-end web products where I can work across frontend experiences, backend systems, real-time features, payments, and scalable production infrastructure.

I've built merchant-facing Shopify features at Scalenut Technologies across Kefi Swatch and Kefi Bundles, working from storefront rendering through backend discount logic. I created Kefi Swatch’s Preact rendering engine with nine display styles and a one-click competitor migration flow.

I rewrote Kefi Bundles’ discount engine from JavaScript to Rust across eight bundle types, reducing instruction count by 90% and input size by 38%. At Explorin, I also built end-to-end job-finder flows in Next.js, backed by Prisma schemas and REST/GraphQL APIs.

I build production-minded products including RydeSaathi, a real-time ride-hailing platform, Lancify, a freelancing marketplace with Stripe Connect payments, and BioSan.ai, an AI medical-report parser. My work spans React, Next.js, Django, TypeScript, GraphQL, AWS, Docker, payments, real-time systems, and AI integrations.
