About

I’m Marcus McNeal, a senior full stack engineer who designs and builds high-traffic web platforms and the APIs that power them. I’ve worked with Python and Node.js to deliver scalable backend systems, and I’ve shipped frontend experiences using React and TypeScript—often with an emphasis on performance, reliability, and clean integration across services.

I also bring end-to-end product focus: setting up CI/CD, defining testing standards, and mentoring engineers to raise quality across the stack. Beyond core web development, I’ve helped bring LLM-based features into production using RAG pipelines and multi-agent workflows, including real-time voice and video assistant experiences that maintain strong quality after launch.
