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 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.

Cover image for Custom SaaS & CRM Platform on Bubble.io
Most businesses don’t need another generic chatbot. They need a real product connected to their operation. As a Bubble developer, I build SaaS platforms, CRM systems, AI copilots, internal tools, and automation dashboards designed around real business workflows. Fast iteration, scalable architecture, and production-ready integrations. Bubble became one of the most powerful ways to launch modern software without sacrificing flexibility. Combined with APIs, AI systems, and custom backend logic, it allows companies to validate and scale products much faster. If you are building an MVP, internal platform, AI workflow, or customer portal, I can help turn the idea into a real product.

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.

Cover image for Hey Guys, new project Arived! Montebello
Hey Guys, new project Arived! Montebello Água e Gás is a local water and gas distributor based in Saltinho, Brazil. The goal was to build a digital presence from scratch — fast, mobile-first, and conversion-focused. The project included target audience research and competitor benchmarking, which led to a deliberate choice: a lean, single-page layout that loads instantly and drives direct contact via WhatsApp. Delivered with Meta Pixel + Conversions API integration, Google Search Console setup, and SEO-optimized on-page structure — all built in HTML, CSS, JavaScript, Figma, Photoshop and Google Stitch deployed on a custom domain.

Cover image for Same brand. Different world. Took HandSkill's
Same brand. Different world. Took HandSkill's website from outdated to premium — without changing who they are. The old site had the right ingredients: strong brand colors, real product photography, clear navigation. But it felt stuck in 2015. No hierarchy, no conversion focus, no visual confidence. The redesign kept the identity and elevated everything else: → Editorial hero layout with product staging → Typography that commands attention → Social proof bar above the fold → Clear CTA that actually converts Built with HTML, CSS, and AI-assisted design — delivered fast, without sacrificing craft. Before → After. Swipe. What do you think — which element made the biggest difference, the typography or the product staging?" #webdesign #redesign #brandidentity #beforeandafter #landingpage #uidesign #cosmetics
