This is my first real vibe coding project. Aguante started as a marketplace idea for football shirt collectors.

The original goal was to connect buyers and sellers of rare, vintage and historic football shirts in a dedicated platform focused on collectors culture. But during the research process, interviews and competitive analysis, we realized something interesting: The real pain wasn’t only buying or selling. It was discovering.

Collectors spend hours searching through Mercado Livre, OLX, stores, Instagram pages and random marketplaces trying to find rare pieces, often with poor organization and low trust.

That insight changed the direction of the project.

Instead of starting as a marketplace, Aguante evolved into a discovery platform - a search engine focused on collectible football shirts.

The platform monitors multiple sources daily, indexing public listings and helping collectors discover rare, used and historic shirts in a cleaner and more curated experience.

This project also became my first real “vibe coding” experience.

The entire MVP is being designed and structured using tools like: - Claude Code - OpenAI Codex - GitHub Actions - scraping automations - AI-assisted workflows

The process has been really interesting because it mixes: UX/UI design, product thinking, scraping pipelines, SEO strategy, collector behavior research and AI-assisted development.

In just two weeks running, Aguante is already indexing more than 12,000 football shirt listings across multiple stores and marketplaces automatically.

Right now, the project is still in validation phase, but it’s exciting to see an idea that started as a simple niche marketplace slowly turning into something much bigger.

More than the stands, it’s collecting.
