Profile
AI and Data Engineer specializing in Generative AI, AI agents, LLM/RAG systems, data engineering, MLOps, and workflow automation. Over 8 years of experience — 5 years in Full-Stack Development and the last 3 years focused on AI and Data — building scalable, end-to-end solutions across intelligent automation, cloud systems, and modern data platforms.
I build AI-powered applications, agentic workflows, ETL/data pipelines, and production-ready cloud solutions using LangChain, LangGraph, n8n, OpenAI, Claude, FastAPI, AWS, GCP, and Azure. My approach combines data, AI, and automation with a practical, impact-driven mindset to ship reliable systems that solve real-world problems.
