Cover image for In a single night I
In a single night I was able to build this awesome diary PWA using by applying my very own framework architecture with Google AI Studio. I'm actually using the app myself for the first time in my career, like I'm the user of my own craft, can't believe I finally made it. Now I can think of how I can sell it, but for you who are reading here you can also enjoy the app for free at the link: https://easyaichatdiary.vercel.app/

Cover image for I was able to build
I was able to build a working AI generated RPG app in 2 days with Google Gemini 3 and my very own framework asasvirtuais (https://github.com/asasvirtuais/asasvirtuais-framework). I used Airtable to store the data and generate images and text based on user provided definitions of the game elements (cards, characters, missions).

Seamless creating of PWA and published to Play Store! A django project using no framework of javascript, was successfully transitioned to PWA! The behaviour is different between browser and PWA, so needing to modify nothing on the frontend was a great achievment!

Stuna is a specialized platform built to organize, connect, and empower the vibrant and rapidly growing manga-collecting community in Brazil. Unlike traditional markets, Brazilian manga culture is deeply shaped by diversity: from regional publishing differences to unique release schedules, limited-edition prints, and small specialized retailers spread across the country. Collectors often struggle with fragmented availability, inconsistent stock, and the difficulty of finding specific volumes, especially from older or niche series. Stuna solves this by unifying collectors, local comic shops, and distributors into a single intelligent ecosystem. Through demand tracking, pre-order management, and community-driven inventory insights, Stuna makes collecting Brazilian manga easier, more organized, and more accessible.
