Killing ResumoFII

ResumoFII shipped in July 2025. It scraped 466 Brazilian real estate funds from B3, downloaded monthly PDF reports, and used Gemini 3.1 Pro to extract structured data into a Svelte frontend. It worked. It was live. Four months later I killed it. The Build ResumoFII started as a way

It's Alive

It’s been a while since my last update, but ResumoFII is finally live. This week I shipped it in it's currently half-baked state and it's available at resumofii.com. I was starting to get tired of being stuck in an endless build loop without validating

Boring Admin Plumbing

Real builders ship. It's been six months and I didn't deploy anything yet. Time to stop reading all the vibe coding hype on places like X because it sounds like everyone is a genius and able to ship complete products in a month 🤨 Anyways back to

Vibecoding a Monthly Report View

Last time I showed how Gemini is able to extract structured data from Brazilian monthly FII reports. I've been iterating/vibe coding ways to display the dynamic report data within the Svelte frontend and hit on something that's interesting enough for the MVP version of the

One Hour

One hour per day is reasonable. It's a manageable amount of time alongside a busy work schedule, exercise, social life and everything else. It's small enough that it doesn't feel like a sacrifice, but consistent enough that real progress adds up over time. Over

29 Test FIIs Seeded into ResumoFII

Things have been moving in my free time. I scraped FII data from B3 and CVM, ran some Python transformation scripts, and seeded 29 funds into ResumoFII. The backend is Rust + Axum + SQLite. The frontend is Svelte + Tailwind. I manually tested some Gemini 2.5 prompts in Google AI Studio

I Invest in FIIs. Reading the Reports Is a Nightmare

I invest in more than 10 Brazilian FIIs (Fundo de Investimento Imobiliário). You can easily purchase them via your online broker. The funds pool investor money to invest in real estate assets either directly by buying properties and renting them out or indirectly by providing loans for residential or commercial
