I build full-stack web, payments, and Solana products with Next.js, TypeScript, Node.js, and PostgreSQL.
NigeriaWhat I'm looking for
I'm building the production stack at SempaiHQ for a Solana-facing content and rewards product, using Next.js, PostgreSQL, wallet login, token-gated access, and on-chain reward checks.
I've built leaderboards, reputation loops, daily rewards, and transaction verification, while maintaining a React and TypeScript design system, API query and index work, and GitHub Actions release workflows.
Through DigiTec Hub Institute and freelance client work, I taught web, backend, and data courses while shipping e-commerce applications with payments, admin tools, inventory, order tracking, and React Native apps with auth, sync, and push.
Since 2020, I've delivered React, Next.js, Django, Node/Express, and PostgreSQL products including business sites, catalogues, internal tools, storefronts, wallet builders, and learning platforms. I'm relocating to Sydney and can start remotely.
