Hola a todos.

Hace años que convivo con problemas de sueño e insomnio, y una de las cosas que más me ha frustrado es no tener un registro claro de cómo duermo, qué hábitos me ayudan y cuáles me perjudican.

Por eso me interesa conocer experiencias de otras personas que también hayan pasado por algo similar.

¿Qué cambios, rutinas o herramientas les resultaron más útiles para entender mejor sus patrones de sueño?

No busco consejos médicos ni recomendaciones de medicación, simplemente conocer experiencias personales y aprender de quienes llevan tiempo lidiando con este problema.

Gracias por leer.

I’ve been building a React Native mobile app connected to a .NET backend as a solo project, and honestly, production bugs taught me more than tutorials ever did.

Three issues that humbled me recently:

🔔 Notifications silently stopped working in production

Everything worked perfectly during testing. In production, Android simply stopped triggering daily notifications consistently because of background process restrictions and battery optimizations. The fix itself was simple. Finding the real cause was not.

🔄 Duplicate check-ins caused by a React re-render

Users occasionally generated duplicate records in SQL Server. After tracing requests for hours, I discovered the frontend was triggering the same API call twice because of a component re-render. One backend validation solved it, but diagnosing it was painful.

🔐 Google authentication was way more fragile than expected

What looked like a simple login flow actually depended on multiple systems being configured perfectly:

• mobile app
• Google console
• backend validation
• token configuration

One tiny mismatch broke the entire flow silently.

What I learned from all this is that debugging distributed systems is a completely different skill from writing code.

The hardest bugs are usually not the ones with obvious exceptions or stack traces. They’re the ones where everything looks correct.

Curious to hear:
What production bug taught you the most?

I built a mobile app solo and ended up learning more from production bugs than from courses.

Three issues that humbled me:

* Notifications silently stopped firing in production because of Android background process restrictions.

* A React re-render caused duplicate check-ins to be sent to the backend.

* Google authentication required multiple systems to be configured perfectly or everything failed silently.

The hardest part wasn't fixing the bugs.

It was learning how to debug systems where everything *looked* correct.

That's probably the biggest skill solo projects force you to develop.
