Over the last 2-3 weeks, I vibecoded the recipe app that I always wished existed - recipeninja.ai . It now includes a fully interactive voice assistant so you don&#x27;t need to get your dirty hands over your new iPad when you&#x27;re cooking.Background: I’m a startup founder turned investor. I taught myself (bad) PHP in 2000, and picked up Ruby on Rails in 2011. I’d guess 2015 was the last time I wrote a line of Ruby professionally. Last month, I decided to use Windsurf to build a Rails 8 API backend and React front-end app, using OpenAI&#x27;s realtime API for voice-to-voice responses. Over the last few days, I also used Claude Code and Gemini 2.5 Pro for some of the trickier features. 35,000 LoC later, this is what I built!The site uses function-calling to navigate the site in realtime as you chat with the voice assistant, which I think is pretty neat.For the long version, see <a href="https:&#x2F;&#x2F;tomblomfield.com&#x2F;post&#x2F;778601470234918912&#x2F;vibecoding-a-production-app" rel="nofollow">https:&#x2F;&#x2F;tomblomfield.com&#x2F;post&#x2F;778601470234918912&#x2F;vibecoding-...</a>I&#x27;d love any feedback you have!Demo video of the voice assistant: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=kRhVc9D5kcg" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=kRhVc9D5kcg</a>Generate and edit new recipes: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=VwwZF6dHcHg" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=VwwZF6dHcHg</a>
