Matthew Kenner
Founder & Lead Developer
Hi, I'm Matthew Kenner, founder of CityLyfe LLC. As a U.S. Army veteran and cybersecurity-focused software engineer, I bring over a decade of experience in secure communications, network systems, and mission-critical infrastructure to commercial software development. I served as a Network Communication Systems Specialist (25H), where I led training for 100+ soldiers and deployed tactical communication systems across multiple countries.
Currently pursuing my B.S. in Computer Science at the University of Colorado Denver (graduating May 2026) with minors in Data Science and Risk Management & Insurance, I combine academic rigor with real-world deployment experience. I've completed advanced NVIDIA Deep Learning Institute certifications in Transformer-Based NLP, Generative AI, RAG Agents, and Agentic AI Applications, staying at the cutting edge of AI/ML technologies.
My technical foundation spans secure software engineering, distributed systems design, containerized application delivery, and applied AI systems. Whether building production web applications with Node.js and Docker, implementing secure Linux environments, or developing automation workflows, I bring the same operational excellence and attention to detail from military service to every project.
When you work with CityLyfe LLC, you get direct access to an engineer who understands both the technical requirements and security implications of modern software systems. I personally handle every aspect of your project, ensuring quality, security, and reliability that comes from military-grade standards applied to commercial solutions.
