I build intelligent products that turn complex technical data into clear decisions — from used-car risk intelligence and predictive maintenance to Solana wallet analysis and autonomous agent dashboards.
Engineering clarity into complex systems.
Rafai Mohamed Taha is a Moroccan automotive engineer and product builder focused on automotive intelligence, predictive maintenance, AI-assisted tools, and Web3 analytics. His work connects engineering logic with modern software products — transforming complex technical signals into clear, practical decisions for users, buyers, builders, and teams.
Beyond engineering, I build and ship MVPs using modern tools like Next.js, TypeScript, Tailwind CSS, Vercel, Prisma, SQLite, Recharts, and AI-assisted development workflows. My work ranges from industrial predictive maintenance and automotive diagnostics to Solana wallet intelligence, autonomous agent dashboards, QR digital menus, and founder-led automotive ventures.
