Engineering Excellence

I am a Senior Full Stack Engineer currently building enterprise-scale solutions at Big Four. I specialize in the intersection of modern web development, multi-cloud architecture, and applied AI engineering.

My philosophy is simple: build products that are blazingly fast, beautifully designed, and technically resilient. I pride myself on optimizing system designs—like this very portfolio which runs across AWS, GCP, and Azure at essentially $0/month.
