At Turnkey ISP, I built and maintained live e-commerce platforms for international clients, including isohorns.com and cyberantennas.com. I developed customer-facing storefront and checkout flows with Next.js, TypeScript, Tailwind CSS, and Shadcn UI.
I designed MongoDB and Prisma data models and implemented backend logic for orders and contact management. When the original product-variants schema failed to scale, I redesigned it and led the migration of legacy database and contact data.
I also fixed a Stripe webhook issue that left paid orders unregistered, and improved invoice PDF generation and product image lookups. My work included multilingual product support with next-intl and Google Cloud Translate, as well as review features and an auto-updating SEO sitemap.
