Senior Full-Stack & AI Engineer | SaaS Architect | DevOps & Cloud

I build production-grade SaaS platforms and AI-powered systems — not prototypes. For 10+ years, I have led development as a Full-Stack Engineer, AI/ML Specialist, and CTO, delivering scalable applications with real business impact. I combine strong backend engineering with cloud DevOps and modern AI capabilities to design solutions that are secure, resilient, and ready to grow.
