What I'm looking for

I seek roles where I can lead NLP and computer vision projects, build production ML systems, and drive automation in collaborative, growth-oriented teams.

I am a Senior Data Scientist and Sr. Consultant with extensive experience building NLP and computer vision solutions, automation pipelines, and multi-agent systems using LangGraph and LangChain. I lead projects involving LLMs (GPT-3.5, GPT-4), RAG, OCR, vector databases, and API development to deliver document retrieval, summarization, Q&A bots, and data structuring for financial consolidation.

I hold a master's in Computer Science (focus on NLP and computer vision) and a bachelor's in Computer Engineering, with research and publications on algorithm education and teaching methodologies. I have worked internationally, collaborated in English-speaking teams, and earned certifications in deep learning, computer vision, and Docker.
