Denis N. AI, Python and Natural Language Processing

My name is Denis N. and I have over 5 years of experience in the tech industry. I specialize in the following technologies: Python, Natural Language Processing, Large Language Model, Artificial Intelligence, Chatbot Development, etc.. I hold a degree in Bachelor of Science in Information Technology, Master of Computer Science (MSCS). Some of the notable projects I've worked on include: ReAct Prompt Framework Realization, Voice Agent for Car dealership, Multi Layer RAG Filtering System (OpenAI, LangChain), Competitor Analysis Workflow with AI (GPT, n8n), AI Powered Diary for Health Domain, etc.. I am based in Chernivtsi, Ukraine. I've successfully completed 12 projects while developing at Softaims.

I employ a methodical and structured approach to solution development, prioritizing deep domain understanding before execution. I excel at systems analysis, creating precise technical specifications, and ensuring that the final solution perfectly maps to the complex business logic it is meant to serve.

My tenure at Softaims has reinforced the importance of careful planning and risk mitigation. I am skilled at breaking down massive, ambiguous problems into manageable, iterative development tasks, ensuring consistent progress and predictable delivery schedules.

I strive for clarity and simplicity in both my technical outputs and my communication. I believe that the most powerful solutions are often the simplest ones, and I am committed to finding those elegant answers for our clients.
