I created a web experience inspired by PS1 game UI, cyberpunk visuals and old internet aesthetics 👾 “UNKNOWN ARCHIVE” is a retro-futuristic inventory filled with posters, CDs and corrupted digital artifacts. I used Google Stitch to generate and evolve the interface with prompts and visual references, exploring motion, hover effects and a UI that feels alive. 🔗 Project: https://stitch.withgoogle.com/preview/9399905294660220176?node-id=f2d2e066aa814c768ee39d333e9008cf @stitchbygoogle #GoogleStitch #Cyberpunk #GameUI #WebDesign

What if CapCut had launched during the Y2K internet era? 💿✨ I reimagined CapCut as CapCut.exe, an alternate digital universe inspired by chrome aesthetics, retro interfaces, CDs and early internet nostalgia. Built using CapCut Design Studio... from idea generation and visual exploration to refining the final creative world. 🔗 https://www.capcut.com/ai-design?shareId=7643629371705720839

Cover image for Boost Web Animation with CapCut: Interactive Portfolio Guide

I’m taking part in the #CapCutDesignStudioChallenge and wanted to share a part of my creation process, even if it goes a bit off topic But since I used CCDStudio in an important part of this project, I thought it was worth sharing here I’m building an interactive PS1-style portfolio, and I used CCDStudio to create the character sprites In the process, I organized the character into different expression states like looking, talking, and blinking The idea was to treat each sprite as a “living state” of the interface, ready to be triggered in real time based on user interaction CapCut DesignStudio helped me quickly test visual variations, keep consistency between frames, and build a simple but expressive visual language designed for lightweight web animation It’s still an early-stage project, but I wanted to share this part because it might inspire other ways of thinking about sprites in interactive experiences Link: https://stedelboux-interactive-retro-avatar-portfolio-775902576268.us-west1.run.app/ #CapCutDesignStudio #Vibecoding #CreativeCoding #UXDesign

Cover image for For this one I wanted

For this one I wanted to try a vampire hunt told entirely from his own eyes, in one continuous shot. I started by making reference images first, the character, the night street, the color mood, so the video would stay visually consistent. Then I used those as references in Seedance 2.5 and built the full 30-second scene with timestamp controls to time out each story beat. You follow the vampire's super speed and rising tension as he closes in on someone, then right before the attack, he bails and speeds off toward a food truck, completely obsessed with a red berry smoothie instead. I liked setting up a classic horror moment and yanking it into something silly.

Software Architect | Technical Direction & AI Delivery

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 AI-Powered OCR Pipeline for Document Processing

Most OCR systems stop at text extraction. The real value starts after the document is read. In this project, I built an AI-powered OCR pipeline capable of extracting text from invoices, contracts, reports, and forms while also classifying the document type and identifying key information automatically. Instead of returning raw text only, the system structures the data into usable outputs for automation workflows, CRMs, ERPs, and AI agents. This reduces manual processing time and makes documents immediately actionable inside business operations. The stack combines OCR engines with LLM-based processing for contextual understanding, keyword extraction, and intelligent classification. The result is a more reliable document processing flow that can integrate directly with APIs, databases, and automation systems. This is where AI engineering becomes practical: transforming unstructured files into structured business data at scale

Cover image for I'm currently building Omnicrm.chat (http://OmniCRM.chat).

I'm currently building Omnicrm.chat (http://OmniCRM.chat). A CRM and multichannel communication platform designed to keep customer conversations, sales opportunities, and operational workflows in a single workspace. Most teams still manage WhatsApp, Telegram, email, proposals, tasks, and customer records across multiple disconnected tools. The result is lost context, duplicated work, and a fragmented customer experience. With OmniCRM.chat (http://OmniCRM.chat), conversations can evolve into opportunities, projects, and tasks without manual data entry. The goal is to connect communication, CRM, and execution into one platform, while creating a foundation for future AI-driven automation across the entire customer lifecycle.

Cover image for Intelligent AI Agent for Business Automation

Most businesses are already experimenting with AI — but very few are using it the right way. A generic chatbot is not enough. What actually drives value is a custom AI agent built around your workflows, capable of calling APIs, automating decisions, and integrating directly with your systems. This is where AI stops being a demo and starts becoming infrastructure. With the right architecture, your AI can handle operations, reduce manual work, and scale processes without increasing costs — from customer support to internal tools, data processing, and beyond. If you're thinking about building a real AI solution tailored to your business, let’s talk.

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.
