How I think about infrastructure.

I design headless, layered systems so each tier scales and fails independently: a Vercel-hosted Next.js frontend at the CDN edge, a Cloudflare R2 image CDN, and a hybrid backend that localizes content by region. The production stack runs on Linux with Nginx and Gunicorn fronting Django over PostgreSQL and MySQL, and I spend real time on performance profiling and security hardening. Everything ships through GitHub-and-Vercel CI/CD with an automated PR-review framework, so velocity never costs reliability.
