Karthikeyan T
AI Engineer • SaaS Architect
I’m a problem solver at heart with 15+ years of hands-on experience and over two decades in the software industry. I design and build production-ready, scalable SaaS platforms by deeply understanding how systems work, identifying real business pain points, and turning them into practical, maintainable solutions. My work focuses on clean architecture, performance, security, and AI systems that ship to real users—not demos.
