Senior Developer with 10 years of experience in Deep Learning. I work with companies and startups on LLM based solutions, including: - text understanding including intent and requirements extraction from texts and validation AI-agents output against this requirements - AI-agent evaluation including such fuzzy problem as a validation of the LLM output - extracting company processes from logs and documentation and AI agent automation along this process - LLM fine-tune using most recent and advanced approaches. For agents evaluation it's useful to iterate on prompts quickly. I developed a pydantic based structured prompts solution to create prompts variation easily and open-sourced it in PromptBuilder library on GithHub. I have over 3 years of hands-on experience in LLM agent development. Previously In Deep Learning I have completed a multitude of tasks for clients in Computer Vision and NLP. In LLM area my portfolio includes fine-tuning LLM models like LLaMA 3 with synthetic dataset generation, creating chatbots and text analysis with simple RAG and Graph RAG approach. My strong skills are: following ML principles, precise planning and delivery. Following ML principles mean that I build a metric oriented pipeline and always choose reliable solutions. I possess a full stack skill set, from training models to their optimization and deployment. I follow with interest the progress in LLM on a daily basis and am ready to implement the new approaches. In terms of programming, I am a Full-Stack developer with a Computer Science background and a Master's Degree in Applied Mathematics and Informatics. My overall experience spans more than 12 years. I enthusiastically take on complex tasks and devise solutions based on my experience and understanding of AI development.
