It's cool, right?

[Leandro Oller @LeandroEOller]

@KumujJain Yes sir, it's a real pain point. And I have two options: I can pay for a SaaS (if it exists) or I'll build my own Employee as a Service 🤣

Does anyone here use QBO?

I'm tired of having to manually enter my supplier invoices, bank transactions, etc., myself. I would love to have an agent that does it for me. Something that connects to my email to check my conversations with suppliers and then logs the invoices in QBO. If anyone knows of an existing solution, that would be awesome! Otherwise, I'll just have to build it myself.

@soloceoai I 100% agree. I know about finance and coding, but I need to learn about the marketing world 😅

Day 6 building my first mobile app

We've done it! Now I have integrated AI that has the context of my pet (breed, allergies, weight, age, vet visits, etc.) and can respond to me based on it 🚀
BTW, I didn't think managing image uploads would be so tough.
Should I launch the beta test if we hit 50 people on the waitlist?

Day 5 building my first mobile app.

Today was actually pretty productive… We got a vet appointment! 🎉

How? Tables and data, the usual.

Right now I’ve got these (plus Supabase’s auth.users):

👉 auth.users → user_id and user details
👉 pets → each dog’s profile
👉 vet-visits → every vet visit
👉 vet-visit-pets → join table so one appointment can include multiple dogs (in case you drag the whole pack on the same day)

Now, should I tackle the Google Maps API next to show nearby parks? Or push harder on the AI chat feature?

[Leandro Oller @LeandroEOller]

Coding, but that sign in the back nails it.

❌Built in silence once... Never again.
✅ Distribution from day one.

That's the only way 🚀
Anyone with me?

[Leandro Oller @LeandroEOller]

@SleepDaizy This is the son of Bill Gates and Steve Jobs, right?

[Leandro Oller @LeandroEOller]

@eibrahim That's a good point, the map could also show vets and groomers, not just parks. The appointment scheduling and frequency feature is easy to improve, because it just requires adding recurrence functionality to what I've already developed.

Day 4 building my first mobile app.

✅User logic implemented
✅Home screen created
✅Pet registration per user
✅Dashboard with quick actions
✅Preview map view of nearby parks (API connection pending).
❌ Beautiful design.

Tomorrow: shaping up the core functions and design.

@yashhq_22 I have a worse one, being ignored and not finding a way to stop being ignored.

[Leandro Oller @LeandroEOller]

@Raredev_co Absolutely! Before, I felt like "wasting time" sharing what I was doing instead of actually improving the product. But now I understand that it's not "wasting time", it's a key step.

[Leandro Oller @LeandroEOller]

This is the face of someone who fucked up.

It took me a year to build the "perfect product". It saved me 10 hours a week. It was technically superior to my competition.

A thread on why I fucked up (and how you can avoid it)👇

[Leandro Oller @LeandroEOller]

@virattt @findatasets Where did you used to work? I mean, doing what?

[Leandro Oller @LeandroEOller]

The only way I could learn this lesson was by losing a year of my life.
Don’t make my mistake. If you’re building something today, don’t build in the dark! Distribute from day one.

If you know a founder who needs to read this, RT the first tweet.

See you in the process! Cheers.

Today, I’m working on a second project (an app for dog owners 🐶)

But the rule has changed: DISTRIBUTION FIRST.

Before writing a single line of code:

✅ I built a Waitlist.
✅ I’m documenting every step on this account.
✅ My personal brand is now my #1 asset.
