Hey all! Me again :) This time, I'm building something for our health 💪. We all love the freedom of freelancing, but it's too easy to forget to take breaks and move our bodies. That's why I'm using Builder to create a simple app that times our work sessions and reminds us to take healthy breaks with guided stretches. It's all about working smarter without forgetting to take care of ourselves! What do you think? 😁

Hey everyone! I’ve been experimenting with a small AI-powered tool for freelancers and I’d love your feedback! 👉 FairRate – Smart Pricing for Freelancers (https://studio--studio-467457356-8d2ad.us-central1.hosted.app/) It’s a simple proof of concept that helps you estimate a fair rate for any job — just paste a project description, choose your experience level and region, and the AI gives you a price range with a short explanation. I built it to solve something I often see here on Contra and among other freelancers that are unsure how much to charge for new projects. I’d love to know what you think, what works, what doesn’t 👀, what could be better. If you have a minute, play around with it, and please drop any feedback or ideas in the comments (is it realistic? not even close?)!

I recently built a landing page for a law firm — but it’s not just a landing page. It’s a way to connect real people with real legal solutions 🤝 . Every section was designed to build trust, highlight expertise, and guide visitors toward what truly matters: solving their problems. Because in the end, great design isn’t only about looks — it’s about creating meaningful connections between professionals and the clients who need them most. If you’re ready to turn your services into something people can feel and trust, let’s talk.

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.

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!
