I’m a senior Python/JavaScript developer with over 15 years of experience building scalable, high-performance software solutions across multiple industries. I specialize in developing full-stack web applications, data pipelines, and AI-driven systems, with a strong focus on backend architecture using Django, FastAPI, and Node.js, as well as modern frontend technologies like React. My core strength lies in AI engineering and automation—designing and deploying LLM-powered agents, RAG-based chatbots, and semantic search systems using tools like LangChain, LangGraph, HuggingFace, and vector databases. I also bring solid expertise in data engineering, ETL workflows, and analytics, working with technologies such as PostgreSQL, MongoDB, Snowflake, and Pandas. In addition to software development, I have hands-on experience in DevOps and cloud infrastructure (AWS, Docker, Kubernetes, CI/CD), along with a background in network engineering and system administration. This allows me to deliver end-to-end solutions that are not only scalable and secure but also production-ready. What differentiates me is my ability to bridge traditional software engineering with modern AI capabilities, building intelligent, reliable systems that solve real-world problems efficiently.
