Technical skills
Work Experience
As a LLM Engineer I have been pivotal in advancing automated digital media strategies that relate to Israel-Gaza war. I worked with Hugging Face, OpenAI API, Llama Index technologies to create online research agents, integrated with Twitter API for data collection, analysis and building geolocation features.
● Optimized GPT-4 API expenses using knowledge graphs and working with AWS & GCP cloud environments.
● I enhanced the RLHF technique by using Google PaLM to implement - 'Optimization by Prompting', and utilize PFET & LoRA to fine-tune models effectively.
MatchUp was created to enable personalized recruitment processes tailored to both the candidate's and the employer's needs. As a researcher, I am developing tailored job description analyses using NLTK with PyTorch and Word2Vec, analyzing candidates’ resumes using LLM, and utilizing transfer learning and prompt techniques to calibrate LLM Transformers using both LangChain and Hugging Face modules.
● Saving time for the 'mentors' who edit and comment on the resumes.
● Reduced mismatches between employers and candidates by more than 80%.
