Your Efanntyo is here to assit you always. I am a seasoned full-stack developer and AI specialist with extensive experience in modern web, mobile, and desktop application development, combined with advanced expertise in artificial intelligence and automation. My technical proficiency spans the MERN stack (MongoDB, Express.js, React.js, Node.js), Next.js for server-side rendering, and mobile frameworks including React Native and Flutter, enabling me to build high-performance, scalable, and responsive applications across platforms. On the backend, I am skilled in ASP.NET, PHP with Laravel, and database management using MySQL and MongoDB. I develop robust APIs, microservices, and secure backend architectures tailored to complex business requirements. Leveraging my proficiency in natural language processing (NLP), machine learning, and generative AI technologies, I create intelligent systems capable of fine-tuning language models, integrating Langchain for enhanced language workflows, and employing cutting-edge computer vision techniques such as image and video processing, object detection, classification, and segmentation. I have hands-on experience with Python-based AI and automation tooling including PyTorch for deep learning, web scraping, and automation scripts. My projects extend to AI-powered contact centers, lipsync technology, and AI-driven process automation that maximize efficiency and user engagement. By combining software engineering with data science, I deliver end-to-end solutions that are innovative, efficient, and scalable. I am committed to writing clean, maintainable code and following DevOps best practices for CI/CD and testing, ensuring seamless deployment and quality assurance. I am passionate about partnering with clients to transform their ideas into intelligent digital products and automated workflows that drive business growth and competitive advantage.

He promises things a lot, but is not able to deliver on them. Aside from that, he always pushes the payment back without completing the project, which feels very strange.
