A clean backend is not about writing fewer lines of code.
It’s about separating responsibilities.
Controller → handles requests
Service → handles business logic
Database layer → handles data
I feel scaling starts from good architecture.
🚀 We just submitted PayAjo for the APIConf × Monnify Developer Challenge!
PayAjo digitizes traditional Ajo/Esusu savings groups by replacing manual coordination with automated contributions, BVN-verified members, secure wallets and in wallet transfer , Monnify-powered virtual accounts, transparent payouts, group chat, wallet transfers, and AI-powered reminders.
Here’s link to what we built(available on both web and app):

App: https://t.co/r9dOTkTwEI
Fun, stressful, and absolutely worth it. There was one moment we genuinely thought we'd have to give up. Right before our demo, our server started misbehaving and nothing was going our way. After a lot of debugging, we got everything back up just in time. 😅
Huge shoutout to @justondev for building this alongside me.
Wishing all the participating teams the very best. 🏆

LLMs don't actually reads words in the actual sense of it. They first break the document into chunks, convert words, phrases and even sentences to tokens and process the tokens (which are much faster)

One lesson every backend developer learns:
Validation belongs on the server.
Even if your frontend checks every field, anyone can bypass it and send requests directly to your API.
My authorization tokens are stored in cookies while all the background works (like sending emails) are handled by celery. Also, I use redis to cache OTP during user verification.
I've finished setting up the authentication. I build my own authentication using jwt tokens. I prefer a stateless authentication over session based which is stateful.
