A unified Flask API powering czvck.com — self-hosted on a Raspberry Pi and served via nginx.
Currently handles contact form submissions, routing messages securely to my personal email via the Resend API. Built as the foundation for all backend services across my portfolio projects — additional endpoints will be added as the portfolio grows.
- Rate limiting — 200 requests/day, 50/hour globally, with a tighter 5/hour limit on the contact endpoint
- Honeypot bot protection — invisible form field silently filters automated submissions without revealing detection
- Secure credential management — API keys stored in environment variables, never in source code
- Reverse proxy — served through nginx with HTTPS, proxied from port 5051
- Python / Flask
- Resend API
- nginx
- systemd (process management)
- Raspberry Pi (self-hosted)
This is intentionally designed as a unified API rather than a one-off script. The goal is a single backend that eventually serves all portfolio projects — network monitoring, MTG price tracking, and whatever comes next.
