Senior Full-Stack Developer | MVP Specialist: React, Next.js

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!

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.
