I am an AI Developer with over ten years of professional experience in software engineering. I began my career as a Full Stack Web and Mobile Engineer, working extensively with technologies such as JavaScript, TypeScript, React, C#, Python, and modern backend and cloud platforms, and I have successfully delivered scalable web and mobile applications across industries including business, education, e-commerce, and enterprise environments. In recent years, my professional focus has shifted fully toward the artificial intelligence field, where I have built strong, hands-on expertise designing and deploying production-ready AI solutions. I specialize in developing AI-powered systems such as intelligent chatbots, AI agents, and virtual assistants using GPT and modern large language models. My experience includes advanced prompt engineering, fine-tuning and training machine learning models, retrieval-augmented generation (RAG), vector databases, embeddings, semantic search, and contextual memory systems. I design and implement end-to-end AI workflows using frameworks such as LangChain, integrating AI capabilities seamlessly into real-world products and business processes. I also develop AI-driven automation systems, including intelligent bots and workflows for platforms such as WhatsApp, Slack, and Telegram, as well as scalable business automation solutions using tools like n8n and Zapier to improve efficiency and customer engagement. My background as a full-stack engineer allows me to build AI solutions that are not only intelligent but also reliable, secure, and scalable. I am highly experienced in deploying AI systems to cloud environments such as AWS, Google Cloud Platform, and Firebase, and in integrating AI services into web and mobile applications. In addition, I work with AI-enhanced Web3 and blockchain solutions, including smart contracts, decentralized applications, AI-assisted trading bots, and automation within Ethereum, EVM-based ecosystems, and Solana. I am committed to delivering high-quality AI solutions with clear communication, timely delivery, and long-term technical support.
