@opencode Go with DeepSeek V4 Pro is the best AI set for coding. $5/month for pretty much unlimited Opus-level coding.

Interesting analysis! How strict do you think Estonia is going to be with the shifting of profits to the US LLC?

I get they don’t charge corporate tax like most other jurisdictions (only on distributions) so they have less to lose in terms of tax revenue. Curious how strict you’ve seen the Estonian tax authority be.

@TheJerzWay How do you get both? Any recommendations?

[David Sert @DavidSrtl]

If this is US-sourced income that doesn’t land on a Colombian bank account, you will be fine as the US doesn’t share information automatically.

For most other developed countries there’s automated exchange of information. But in LATAM in practice this is not really used. The capability is there, but the tax collection agency doesn’t have the systems nor manpower to act on the data.

Yet….this is like living with the doubt that an investigation could happen.

What I do and recommend:
-> become formal (M visa)
-> open Colombian bank account
-> add living expenses to it and spend (what a local would do)
-> declare every year based on what lands in Colombia

If you’re paying some taxes it’s very unlikely you’ll get investigated.

this is real on the ground advice after consulting with local lawyers.

@VincentVentalon Encore mieux: demande a ton AI favori de faire le setup Cloudflare pour toi, en 3 minutes c'est réglé. tu couples ça a un bon VPS hertzner a 4 euros par mois + coolify et tu as une infra de ouf pour l'équivalent d'un café

Here on X we're at the cutting edge of tech...99% of normal people still have no idea how to vide code stuff for their needs.

Now, because the barrier to entry is low to build software, this opens the door for many new micro-SaaS: software that's specifically tailored for a very niche market.

@hispanicnomad Time to move 🤣

@totoche Qu’est ce que tu as essayé comment méthode de distribution? Je suppose tu vas aller chercher les déçus de linktree ou bien scraper les profils des influenceurs qui n’ont pas de link-in-bio? Apify peut être pas mal pour te récupérer les données sans gérer l’infra et à bas coût.

Just added the word “comment” to muted words on here and the timeline feels great again

[David Sert @DavidSrtl]

No I don't want to comment to get your free guide or report, just post it here instead

@AlexEngineerAI any chance on running this on a VPS and spin up a cc instance with it? this would be a game changer...

building your own MCPs is claude code's best lifehack

@benCBai @Al_Grigor which codex plan are you using?

[David Sert @DavidSrtl]

@euboid How much usage is that roughly for you to reach the limit? Claude is hitting limits quite quickly now so many of us are looking for alternatives.

[David Sert @DavidSrtl]

No doubt you do need a reputable residency to avoid these kind of issues. Paraguay, Panama, Thailand, UAE...whatever the case but do get some proper tax residency. It's a ticking time bomb until banks find out and you want to be prepared before it happens.

Same goes for account diversification. You DO want to open bank accounts in 3-4 different jurisdictions so if one gets blocked you can get back on your feet easily.

@anthropic is forcing us OUT into codex

codex even has a free plan rn
