Hello, World!

In this profile you can follow my journey in to coding.

I started to "vibe code" in December 2024 and, since then, I've build alone:

1) A web aplication for my family company, currently in production, including:

- User login;
- Payment processing;
- CRM;
- Task management;
- WhatsApp automation with API;
- Inventory and cash control;
- Multiple reports;
- Extensive logging;
- API integration for contract signing;
- Facial recognition for attendence;
- Booking for private lessons;
- Others minors features.

2) A software for a local hedge fund:

- Beautiful landing page (https://t.co/B94U0rcrVk);
- System for order sending in mass;
- Cash in account control;
- Portfolio Sync;
- Data fetching and backtesting;
- Real time negociation data storage;
- Order tracking for big players;
- Position control system for clients;

---

Now I think i might be ready for something bigger.

Do anyone have a suggestion?

I've being using Opus 4.8 in the last couple days and it seems way behind Codex.

It makes stupid mistakes that Codex never did it the same codebase.

I wonder if I'm the stupid one by dont being able to use it properly or if Claude just dominate the Enterprise market by marketing/positining.

For me, Codex is sooo much better!!!

[Matheus ➔ www.up-gestora.com.br @AI_Dev_For_Fun]

I'm a Codex poweruser since dez/jan.

After Fable released, I bought the Claude Max plan to try it.

Took some time to get used to, but I really started to like Fable on the second day. It could do things I couldn't even grasp with GPT 5.5 and Codex.

However, Opus 4.8 sucks.

They are defending Bitcoin exactly at 60k.

It has happened several times that the low was exactly 60,000.

If it breaks (it just broke), it's all downhill from here. Let's see if I get this right!

Give it an endless task and a minimum time limit.

Example:

Build this game (explain the game, framework and etc) for me. Work for no less than X hours. Iterate every loop based on the description of the game.

Keep improving levels, visual, testing bugs, making fixes, adding new functionality and etc until the X hours timeframe.

People that run 24+ hours Codex tasks

Can you share what you’re running exactly?

Everyone is sharing the hours but not the task itself, I feel that most of them are just engagement baits

This internal model we built is astonishing.

The way the system somehow predicts breakouts and its direction with more than 70% accuracy doesnt stop to impress me.

[Matheus ➔ www.up-gestora.com.br @AI_Dev_For_Fun]

I never thought that i would need more compute this soon.

Time for some hardware upgrades it seems 😅

[Matheus ➔ www.up-gestora.com.br @AI_Dev_For_Fun]

That's all I can say for now!

In honor of OpenAI, today is my turn for a vague posting:

We had another breakthrough here at UP gestão over the weekend, and today with the help of Codex.

150 GB of new data, ~20k backtests, and an unbelievable risk/reward asymmetry (already running in a live account today).

@pedroaccorsi_ Parabéns!

Assim que tiver mais volume aqui na gestora, tenho interesse em ter acesso as suas posições e te pagar por isso mensalmente após uma auditoria do track record.

[Matheus ➔ www.up-gestora.com.br @AI_Dev_For_Fun]

@VictorTaelin Te sigo há meses e não fazia ideia que você é brasileiro kkk

With all due respect, it seems like Polymarket doesnt agree with you:

[🍓🍓🍓 @iruletheworldmo]

happy release day one and all.

this will go down as the most monumentous day in human history.

(it’s a word, go away)

it’s one small step for man, and one mighty giant leap for ai.

happy release day to all that celebrate 🥹

what upcoming release excited you most?

-the SUPER APP
-the SPUD
-the IMAGE-GEN

for me. it’s all about the glorious combination.

@PeuAvena @richardrx Pedro, tenho uma gestora de recursos e gostei da Golden, bem como da forma que vocês estão fazendo o marketing.

Gostaria de falar contigo para buscarmos alguma sinergia. Pensei em um Ad dentro do seu app, por exemplo.

Pode me chamar na DM ou no Whats 43 99181-1304 ?

[Matheus ➔ www.up-gestora.com.br @AI_Dev_For_Fun]

@bencera I started a Polsia trial yesterday.

I loved it in the first few minutes and got two of my partners to try it as well.

Then, suddenly, all of our websites started showing the error in the screenshot. Could you help us troubleshoot this?

Polsia couldn't fix it.

Really nice video for understand how to scale vibe-coded software and startups:

If you vibe code, you should watch it!

[Matheus ➔ www.up-gestora.com.br @AI_Dev_For_Fun]

It was a 200 usd low ball, so i refused.

I'm still impressed with the reach tho.

[Matheus ➔ www.up-gestora.com.br @AI_Dev_For_Fun]

Crazy: I just added AutoWhats (https://t.co/GJBVMlN54f) in @TrustMRR from @marclou and I already got a buy offer.

I havent even listed for sale!
