Show HN: Open-source certificate from GitHub activity
brendonmatos Sunday, January 18, 2026I built this as a small side project to learn and experiment, and I ended up with this!
I used a subdomain from my personal portfolio, and everything else runs on free tiers.
The project uses Nuxt, SVG, Cloudflare Workers, D1 (SQL), KV, Terraform, and some agentic coding with OpenAI Codex and Claude Code.
What started as a joke among friends turned into a fun excuse to build something end to end, from zero to production, and to explore a few things I’d never touched before.
I’d really appreciate any feedback or suggestions.
