Need someone who can improve your website, identify software issues, or solve technical problems? I help businesses build better digital experiences through front-end development, manual QA testing, and reliable technical support. Whether you're launching a new website, fixing bugs, or validating a web or mobile application before release, I focus on delivering organized, accurate, and well-documented results. My goal is not only to find issues but also to help you understand them and move toward a reliable solution. My work includes front-end development with HTML, CSS, and JavaScript, responsive website updates, manual website and software testing, bug reporting, cross-browser testing, Windows technical support, technical documentation, and Brazilian Portuguese localization.

Do you have the AI technology to disrupt the market, but need a website that conveys the same authority and innovation? Many AI projects fail to convert simply because their websites look amateurish or perform poorly. I help AI founders transform their models and tools into high-impact visual products. I’m not an "Elementor block-dragger." I develop interfaces using Full Code (HTML, CSS, JavaScript) to ensure your site is lightning-fast, lightweight, and fully customized to your product. What I do for your AI project: High-Conversion Landing Pages: Focused on product demos and lead generation. API Integrations: I connect your front-end directly to your AI model's logic cleanly and efficiently. Pixel-Perfect Design: Modern, clean, and responsive interfaces built to convert visitors into paying users. Extreme Performance: Sites optimized for instant loading, which is essential to keep users engaged with complex tools. I know you don’t have time to deal with technical design headaches. You need a developer who speaks the language of an AI founder and delivers results that impress both investors and clients. Ready to take your AI project to the level it deserves? Send me a message, and let’s discuss the interface for your tool.
