Need a Shopify custom app, a store-to-ERP/warehouse integration, or a full-stack platform built from scratch? I build the technical backbone that turns growing eCommerce operations into scalable businesses. WHAT I BUILD: • Shopify custom apps (API scopes, webhooks, Admin API) • Store ↔ warehouse/ERP middleware (real-time sync, inventory, tax) • Full-stack SaaS platforms (React + Node.js + Supabase/Postgres) • Stripe payment flows + subscription logic RECENT WORK: • Shopify ↔ Nyehandel middleware, real-time order sync, inventory across multi-country EU stores, dynamic VAT, Stripe payments • Glitch Engine — hiring platform with video pipelines + email automation • Bali Visa — visa application platform with document workflows + payments • Portugal Residency Visa — D7, D8, Golden Visa application platform • Shopify Custom App for Lovable platform's Shopify integration • Biomedical AI miner on Bittensor TAO network STACK: Node.js • React • Next.js • TypeScript • Tailwind CSS • Supabase (Postgres + Edge Functions + Auth) • Stripe • Shopify API (Custom Apps, Webhooks, Admin API) • FastAPI • Firebase I work with founders and small teams who need technical execution they can trust. If your stack is broken, your integration is fragile, or you need to ship something custom, let's talk.
