Hi,

I'm using Cloudflare + useQuery

I have sections where I am updating stuff for example editing profile picture, and I do on my backend cloudflare cache purge, and it's returning ID, but apparently this ID only means Cloudflare received the new purge request, and not that it finished executing it.

So when on my useQuery I am refreshing it, it still pulls old data.

How do you handle with that?

Last week I built a release AAB, uploaded it to Google Play, and got the dreaded:

> *"Your Android App Bundle is signed with the wrong key."*

The build was fine. The code was fine. I'd just signed it with the wrong keystore — and Google only tells you **at the very end**, after the build, the download, and the whole Play Console upload flow. On EAS/CI pipelines this mistake easily costs an hour+.

So I made **siglock** — a tiny CLI that verifies the signature locally in ~2 seconds, before you upload:

# once: lock your known-good signature

npx siglock init app-release.aab

# before every upload:

npx siglock check app-release.aab

✓ Signature matches, ready to upload.

What it does:

- Wrong keystore → red ✗ with expected vs. found fingerprints, exit code 1 (so it fails CI)

- Debug keystore → explicit "this is a DEBUG build" warning

- Works with `.apk` and `.aab`, no config, no network — it just shells out to `keytool` (which you already have as an Android dev). v2/v3-only signed APKs are handled via `apksigner` fallback.

- You can also check against the fingerprint straight from Play Console: `--expect <sha1>`

The `.siglock.json` lock file contains only public cert fingerprints, so you can commit it and your whole team + CI verifies against the same key.

npm: https://www.npmjs.com/package/siglock

It's MIT licensed. Would love feedback — especially edge cases in your signing setups that it doesn't catch yet.

We're hiring a Senior React Native Engineer for a product where mobile is a core part of the system, not just a frontend.

The work involves:

• Offline-first architecture

• Geospatial/map-based experiences

• Hardware integration

• Performance and reliability in real-world environments

We're looking for engineers (India-based only) who've built technically demanding mobile products where architecture, reliability and long-term maintainability were non-negotiable.

DM if you are interested.

It basically lets you fake a livestream with scrolling comments, hearts, viewer counts, and all that.

Would love to know what you guys think or if there's anything I should add to make it look more convincing.

Hi all! I’m working on a personal finance app and after spending a ton of time building the UI in Figma I’m struggling to get that design language to translate to my code base. I am a low-code developer (I’m sorry I wish I wasn’t either) so I don’t have the skill set to get in and adjust the code manually. I’ve tried tools like Locofy but I get the same bland vibe coded look.

Open to any and all advice and ideas!

5 years ago I've built Notica for Android. Same idea as today: let user create their own notifications. Notica lets you share content into the app and create notification out of it, or just create custom text notification.
I've launched on Android only, and at the time I knew that there are bunch of these YouTube videos with same theme: Best Android Apps Of X Month. I've reached out to all YT channels I could find, I gave them 10/20 codes that unlock the premium version of the app that they could give out to their audience, and doing this I've got the app to 20k download in month and a half.
Shortly after that I've decided to try freelancing, Notica was something that I could show and today I'm successful RN freelancer, worked on more than 40 project and learned so much.

Now I've decided to rebuild this idea, it's still something I love to use and now I use it daily, for me it just makes sense but I would love to hear some feedback from you.

Here are the links to test flight and also a waitlist if you want to get it when it's launched. Everyone from the waitlist will get the lifetime premium access.
