I’m a full-stack developer with strong expertise in Artificial Intelligence (AI), Machine Learning (ML), and Large Language Models (LLMs). I build smart, data-driven applications that integrate intelligent automation, natural language processing (NLP), and predictive analytics to deliver innovative, scalable solutions for businesses. On the backend, I work extensively with Python (Django, Flask, FastAPI), Node.js, and PHP frameworks including Laravel, CodeIgniter, Joomla, and Magento. On the frontend, I develop modern, high-performance web and mobile applications using ReactJS, React Native, Swift/SwiftUI for iOS, and Kotlin/Jetpack Compose for Android. I also specialize in custom WordPress development, from theme and plugin creation to full-scale, tailored CMS solutions, ensuring functionality matches your exact needs. My UI/UX toolkit covers HTML, CSS, JavaScript, jQuery, and Bootstrap, with a focus on clean, user-friendly design. Beyond application development, I have hands-on experience with Blockchain-based applications, Cloud management (AWS, Azure, Google Cloud), and DevOps workflows (CI/CD pipelines, containerization with Docker/Kubernetes, and server automation). My approach is to combine technical expertise with an understanding of business goals, delivering high-quality, scalable, and future-ready solutions that not only meet but exceed client expectations. menos -
