Bought a new domain yesterday 😬

This time, I will

- solve my own problem (no pmf guessing)
- no cofounders
- real SaaS (no ops)

Can everyday be Sunday?

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]

[Seifeldin Mahjoub @SeifSayed]

Making an ADHD app to solve my own ADHD.

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

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.

[Seifeldin Mahjoub @SeifSayed]

A single good Cursor prompt = 2 hours saved.

A single bad one = 5 hours of “wtf was that, that doesn't even exist” cleanup.

[Seifeldin Mahjoub @SeifSayed]

someone please add a ping when Cursor agent is done, hate to keep the AI gods waiting for me

You get through the lonely chapter of life where you’re more ambitious than your old friend group but don’t have enough proof for your desired friend group by focusing on the work, not the scoreboard.

The scoreboard matters, but you can’t score without first being good. And you can’t get good without first being bad.

[Seifeldin Mahjoub @SeifSayed]

@shadeed9 Congrats Ahmad!

[Seifeldin Mahjoub @SeifSayed]

What are you using to create Logo’s for your apps?

[Seifeldin Mahjoub @SeifSayed]

Best way to prepare for daily 💪

[Seifeldin Mahjoub @SeifSayed]

@rchase I’m curious, how many agents do you have running most of the time?
