@zander_supafast Fantastic, do you have a skill for that?

[Seifeldin Mahjoub @SeifSayed]

@autisticadhdco Have you found any AI powered apps that help ease the struggle?

[Seifeldin Mahjoub @SeifSayed]

It didn't in the end.

[Seifeldin Mahjoub @SeifSayed]

Does branding matter? Let's see.

🪐 Just launch a rebranding for kawkb, my small vacation rental platform.

Happy with shadcn so far, rebranding was smooth!

Next up:

- SEO & perf
- Monitoring (for the next ads wave)
- Cutting cloud costs.

Nuff Bleeding.

Day job: k8s, tens of pods, complex release cycles.

Building at night: push to main, docker compose, blue green.

Feeling like a true gemini

[Seifeldin Mahjoub @SeifSayed]

The excitement I get when my tokens are reset is concerning.

I preferred the old days where programming was free.

When local models?

[Seifeldin Mahjoub @SeifSayed]

I built an app that solves my personal issues which is great.

3 months in, and I can see that it works.

However, I’d like to see if I can turn this into a product.

Let the marketing games begin.

Can everyday be Sunday?

[Seifeldin Mahjoub @SeifSayed]

Cursor keep teaching me new bash commands.

Dev life in 2025 is wild.

[Seifeldin Mahjoub @SeifSayed]

Whoop Whoop.

I can finally run more than 2 agents in parallel.

not 10x dev yet, but closer every day.

[Seifeldin Mahjoub @SeifSayed]

@marcelkargul Apus will be :)

[Seifeldin Mahjoub @SeifSayed]

@thedankoe Thanks Dan, thats reassuring!

Making an ADHD app to solve my own ADHD.

Sounds like the most ADHD thing ever, lets see where this goes.

[Seifeldin Mahjoub @SeifSayed]

Snow outside.

Dumbbells inside.

Winter won’t stop me.

@shadcn The best thing that happened to frontend development since tailwind.

Congrats 🎉

[Seifeldin Mahjoub @SeifSayed]

I was skeptical about prompt engineering, just like I was with Tailwind.

I was wrong on both.

Apus is basically powered by 2–3 solid prompts.
