I also developed the WWAH platform with Next.js and Node.js, including authentication, role-based access controls, and university search features. Previously, I developed the LSIT website and a Gemini-powered chatbot at Khawarizmi Technologies, and built AI and e-commerce applications at Socialist Fox.
