Show HN: Open-source certificate from GitHub activity

https://certificate.brendonmatos.com
11•brendonmatos•10h ago
I 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.

Very cool! Any plans to add more badges specific to big open-source projects like React, Linux, or Git?
brendonmatos•10h ago
Great idea. totally doable for sure
holg•6h ago
Nice idea, how about even more badges? Might be some challenge for the clean looking Certificate...
brendonmatos•2h ago
yea, it really is a challenge! currently, I have a sorting working to fetch the most relevant badges. I only show the top 3 to keep the certificate clean
