I've been freelancing for several years now, working my way up to Top Rated status. Started with PHP and WordPress sites, learned React when clients needed modern interfaces, picked up Python for AI projects, and along the way realized many clients need design too. So I learned Figma, logo design, and UI/UX basics. Most of my work falls into a few categories: fixing WordPress sites, building React applications, creating APIs with PHP or Python, designing interfaces in Figma, and lately, adding AI features like chatbots. Sometimes I'm designing a logo in the morning and integrating OpenAI in the afternoon. Variety keeps it interesting. I handle complete projects - from initial Figma mockups to deployed applications with SEO optimization. It saves clients from hiring multiple freelancers. Need a logo? I'll design it. Want to see the website design first? I'll create Figma prototypes. Ready to build? I'll code it in React or PHP. Need it to rank on Google? I'll handle the SEO. My toolkit includes PHP, Laravel, WordPress, React, Python, Node.js, Figma for designs, Adobe tools for logos, and AI integration with OpenAI. Not claiming to be the world's best at everything, but I'm solid at all of them and that combination is useful for most projects. The Preferred Freelancer badge came from delivering consistent work and maintaining good client relationships. I respond quickly, explain technical stuff in normal language, and if something's outside my scope, I'll tell you honestly. Whether you need a logo, a Figma prototype, a WordPress fix, or a full AI-powered web application, let's talk about what you're trying to build. Available for both hourly and fixed-price work. menos -
