I’m currently open to freelance and contract opportunities in full-stack development.
Over the past few years, I’ve worked on building scalable, secure, and business-focused web applications across both frontend and backend development. My experience includes working with ASP.NET Core, .NET MVC, React, Node.js, Angular, SQL Server, MongoDB, REST APIs, authentication, clean architecture, performance optimization, and deployment workflows.
I’m comfortable contributing to full-stack web applications, backend/API development, frontend interfaces, dashboards, SaaS platforms, internal tools, feature enhancements, and product improvements. I enjoy building solutions that are not only functional, but also maintainable, scalable, and aligned with real business needs.
If you’re looking for someone who can contribute across the stack and help turn ideas into reliable products, I’d be happy to connect.

A fast, easy-to-manage portfolio website, built the way I build business websites for clients.
The site runs on Next.js with Server Components, so pages arrive with their content already in place for visitors and search engines. All content, including projects, services, experience and contact details, is managed in Sanity CMS. Updates happen in a dashboard, not in code, so no developer is needed for each change.
What went into it:
Next.js, React 19 and TypeScript for the foundation.
Tailwind CSS v4 and shadcn/ui for a consistent, responsive design system.
Framer Motion and GSAP for scroll animations that guide attention.
AVIF and WebP images at multiple sizes for lighter pages.
A server-side contact form with validation and email delivery through Resend.
Finally it was deployment on Vercel.😍
Test results: performance grade 83, 923.6 KB total page size, 2.16 s load time, 25 requests.
If you need a business website, e-commerce store or landing page with a CMS you can manage yourself, this is the kind of build you can expect.
Showing the stack next to the live site makes this read like a real case study.
Hi, I'm Kauê, a full stack developer from Brazil 👋
I build Python automations, web scrapers and complete web apps: REST APIs in Go and Python with React or Vue on the front end.
If you have a task someone on your team does by hand every week, there's a good chance a script can do it in minutes.
Open for new projects. Send me a message with what you need!

The dual agent pipeline creating atomic commit plans and the live SSE stream makes the review loop feel almost instant.
