Cover image for THE CHALLENGE Maintaining a study routine
THE CHALLENGE Maintaining a study routine is difficult when progress is scattered across notes, timers, and apps that stop working at the exact moment a learner loses connection. THE SOLUTION Trilho is an offline-first study habit tracker concept built around daily focus, visible streaks, and a resilient routine that keeps moving even without an internet connection. WHAT I BUILT • Daily focus timer and study-session flow • Habit tracking with streaks and calendar history • Weekly progress charts and goal visibility • Offline-first states with automatic sync messaging • Responsive desktop and mobile product experience • Accessible task controls and motivational feedback DESIGN APPROACH The interface pairs warm coral with lavender, cream, and deep navy to make productivity feel optimistic rather than demanding.

Cover image for I would like to talk
I would like to talk about software architecture, I really would like to put into a few words what it takes to make a team of developers agree on an architectural decision shift to prevent a complete disaster in an unplanned project. What it takes to look to a codebase and visualize when and where it over-complicates things due to a lack of initiative, combined with a blind following of a status-quo, and talk about how every industry does the same, creates more problems than it solves and post-pones real solutions. I really would like to be able to do that, but talking about these things doesn't get people very excited, it actually makes everyone depressed, so here is a bunch of cool pictures of the app I made with very own my Architectural Framework which empowers LLM models to build apps without falling to common industry mistakes and lack of specific direction. Interested? Send me a message!

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’m taking part in the
I’m taking part in the Lovable Challenge, and this time I decided to start with a real problem from a real person: my friend Ana Mi, an independent tattoo artist from São Paulo. A lot of her bookings happen through social media. Clients ask about prices, sizes, availability, and payments and she has to answer everything manually. So I thought: what if booking a tattoo felt more like visiting an art gallery? That’s how INKROOM was born. 🖤 A place where people can discover Ana’s work, choose a tattoo, customize it, book an appointment, or even send their own idea for a custom quote. And Ana can manage requests, appointments, payments, and her tattoo collection all in one place. Less time managing messages. More time creating. Built with Lovable for the Lovable Challenge 2026.

Cover image for What if an ancient Egyptian
What if an ancient Egyptian relic was actually the hero of a lost retro console game? For the FLORA Museum Challenge, I reimagined the "Faience amulet in the form of a tree frog" (Ptolemaic Period, 330–30 BCE) from The Metropolitan Museum of Art’s Open Access archive into a playable, low-poly 32-bit platformer hero. 🏛️ Original Met piece: metmuseum.org/art/collection/search/243774

Cover image for WHAT WE WEAR TO PROTECT What
WHAT WE WEAR TO PROTECT What if historical armor left the museum and walked into a 1990s fashion editorial? For the #FLORAMuseum challenge, I used four original armor pieces from The Met as my creative brief — without changing the pieces themselves. I only changed the context: real models, fashion photography, a magazine cover and a VHS-style behind-the-scenes. 5,000 years of protection. One new context. Original references from The Met: https://www.metmuseum.org/art/collection/search/24008 https://www.metmuseum.org/art/collection/search/25640 https://www.metmuseum.org/art/collection/search/23205 https://www.metmuseum.org/art/collection/search/24671 Built with @floraai #FLORAMuseum
