About

I love building apps that help people become better at something. Read4G: Helping people learn German through reading, vocabulary, grammar, listening & writing. Loniva: Helping people train their cognitive abilities through fun, engaging brain games. I’m fascinated by how technology can make learning and self-improvement more accessible, practical, and enjoyable. Always building, experimenting, and looking for ways to create products that have a positive impact.

What auth provider are you using in your stack, and would you choose it again?

Curious what the community is running for authentication/authorization in their apps (e.g. Auth0, Supabase Auth, Clerk, Firebase Auth, Cognito, etc.)

A few things I'd love to hear your take on:

  • What provider are you using and what's your primary stack? (e.g. Next.js + Clerk, Go + Auth0, etc.)

  • What's the one thing that surprised you , good or bad ?

  • Would you make the same call today? Especially curious if you've hit scaling pain.

For context: I'm building a B2C application with my own database layer, and currently in the process of evaluating which authentication provider best fits the architecture. Trying to understand how others are handling the auth <> database relationship and what influenced your final decision.
