Full Stack Engineer with 5+ years shipping production systems. I own products end-to-end — from database schema to checkout flow to deploy pipeline.

I built and operated an e-commerce platform that generated US$90,000+ in sales. Not a side project. A real business with real customers, real payments, and real uptime requirements.

Currently focused on React/Next.js frontends, Node.js backends, and e-commerce systems (Shopify, headless commerce, custom integrations).

Frontend        React · Next.js · TypeScript · Tailwind CSS · Responsive Design
Backend         Node.js · Express · REST APIs · GraphQL · Webhooks
Databases       PostgreSQL · MySQL · Prisma · Redis
E-commerce      Shopify (Liquid, Hydrogen, Storefront API) · Payment Gateways · CRO
Infrastructure  Vercel · Docker · GitHub Actions · CI/CD · AWS · Firebase

Problem A retail business needed a high-converting online store with custom checkout logic, inventory sync, and room to scale.

Solution Built the full stack: React/Next.js storefront, Node.js backend, Shopify integration, payment processing, and an admin dashboard for orders and inventory. Optimized for speed, SEO, and conversion.

Impact

• $90,000+ in total online sales
• 40% faster page loads after frontend optimization
• 60% reduction in manual order processing
• 99.9% uptime during peak traffic
