Jadson Nogueira
Senior Full-Stack Developer based in Toronto, Canada. I build production-ready web applications from the ground up — from database architecture to pixel-perfect interfaces — with a growing focus on AI-powered solutions.
My portfolio spans SaaS platforms, dark kitchen systems, NFC monitoring tools, real-time translation services, and government automation. Each project was built to solve a real business problem, deployed and running in production.
I specialize in Next.js, NestJS, Node.js, MongoDB, and PostgreSQL, with deep experience in Stripe integrations, real-time systems, and infrastructure automation with Docker, Nginx, and PM2.
Currently exploring AI integration through real-time translation systems powered by Azure Speech, Google Translate, and Gemini AI — with strong interest in Toronto's AI ecosystem, including Vector Institute research, fintech, and healthtech applications.
