Building MysteryDog (MVP - Bangkok's pet-friendly community platform.
Transitioning from CTO to focus full-time on our own product.

Building an app in Bangkok, Thailand. No, it's not what you think.

The problem: Bangkok is awesome for dogs, but finding a pet-friendly cafe is a total gamble. My co-founder Alex and his girlfriend Meaw learned this the hard way with their dachshund, Mushroom.

So we built the beginnings of a solution: MysteryDog App. It’s a verified directory of pet-friendly places. But that's just the start. We're building a community, not just a product.

🔐 Getting @better_auth setup was a breeze. Better Auth config is super simple and made integrating all these social sign-on options incredibly smooth. Seriously, it just works.

Just look at how clean this is

📢 Authentication with all the social sign-on options on @expo powered by @better_auth.

New feature just dropped for MysteryDog

We wanted to make signing in as easy as possible for our users in Bangkok, no matter what platform they use.

Thread below on how we set this up. 👇

~$ That's the sound of thousands of pet-friendly places being migrated.
~$ I wrote a script (with some help from AI, of course) to move all our old data to the new platform.
~$ I'm really hoping it doesn't fail - I'm ready to move on to the next feature.

~$ 21m 5s later, it's done. Our database is complete and ready to go!

What do you think of this stack for building a platform like MysteryDog? We're a small, scrappy team and are always open to suggestions. Let us know!

Alright, let's talk tech stack for building 🦴 MysteryDog.

The MysteryDog Tech Stack:

📱 Mobile: React Native @expo
🎨 Styling: @nativewindcss
⚙️ Backend: @nextjs
🔗 API: @trpcio
🗂️ ORM: @prisma
💾 Database: PostgreSQL @supabase
🔒 Auth: @better_auth
✉️ Mail: @resend
📈 Analytics: @posthog
🌐 Hosting: @vercel & @awscloud

We're heavily inspired by the T3 Stack, thanks to @theo incredible work, and using a monorepo setup with @turborepo to manage everything.

My favorite part? TypeScript everywhere. It gives us a ton of confidence to ship fast.

I'll share more details on why we chose each piece in the thread below. 👇

[Yeem Chantha (nawan) @yeem_chantha]

We're using Posthog for analytics to understand our users, Resend for transactional emails, and Vercel for our web app's seamless deployments. The goal is to use best-in-class tools that help us move fast.
