@spectrumsun
I build and lead scalable full-stack web, real-time, and AI-powered applications.
What I'm looking for
At Living Group, I lead engineers building and scaling frontend and backend product versions, from Node.js APIs and MongoDB to React and Next.js interfaces. I provide architectural guidance, code reviews, and technical direction for secure, high-performance systems.
I've built real-time streaming, video-call, chat, and notification systems with WebRTC, mediasoup, WebSockets, Socket.IO, and Firebase. My work also includes AI-powered chatbots, prompt engineering, workflow automation, and integrating AI assistants into applications.
Across Andela, Wellthy, eBanqo, Ingryd Academy, and contract teams, I've shipped production web applications, migrated Django pages to React, developed REST and GraphQL integrations, and automated cloud deployments on AWS. I enjoy creating maintainable systems with strong testing, monitoring, CI/CD, and collaborative Agile delivery.
