Lidia P.

⭐ Expert-Vetted - part of top 1% experts on Upwork I specialise in Machine Learning for NLP applications, with 5+ years experience as a NLP Engineer. I currently focus on Generative AI & RAG pipelines, using LLMs like GPT3.5, GPT4, and open-source solutions like Llama, Mistral, Zephyr. Specifically, I do ML training, fine-tuning, model deployment, LangChain app development, text embedding and prompt engineering. ⭐️ What sets me apart from the mass of "AI experts" on Upwork ? 👉 over 3 years experience working for industry leaders such as Amazon and Apple, developing Natural Language Understanding for smart assistants Alexa and Siri. I have been through extremely competitive recruiting processes to become an NLP Engineer, and worked alongside top talents, delivering innovative solutions with the highest standards. I left Amazon at the end of 2021 to pursue my freelancing career, here is what Amazon wrote in my exit letter: ❝ Ms. Pierre possessed outstanding and profound knowledge and great expertise, which she continuously used in a highly profitable manner for our company’s benefit. Due to her excellent analytical skills and very quick comprehension, she developed perfect solutions, which she consistently and successfully implemented into practice. Ms. Pierre planned all of her work very well, she always delivered her projects on time and was highly result-oriented. She was always reliable and highly accurate in her work.❞ My expertise: ✔️Design and develop advanced AI/NLP solutions for NLU, NLG, chatbot development, conversational/generative AI, Q&A, information extraction, text classification, summarizig, NER and more ✔️Transformers models: auto-encoders (GPT3, PGT4, PaLM, Llama2, Mistral..), auto-regressive (BERT, RoBERTA), seq2seq (T5..) ✔️HuggingFace Transformers and Sentence Piece, open source LLMs & OpenAI solutions ✔️Fine-tuning and optimization techniques (PEFT, QLoRA) ✔️ML/DL Frameworks and libraries: PyTorch, sickit-learn, SpaCy ✔️LLMs applications with LangChain / Llama Index ✔️Retrieval-augmented generation RAG: VectorDB (Pinecone, ChromaDB, FAISS..), Embeddings, Retrieval agents ✔️End2end solutions: AWS Sagemaker, Docker, AWS Lambda, RESTful API ✔️Data ingestion, cleaning, analysis, pre-processing, SQL ✔️8 years experience with best practices for Python development, I hold a Master Degree in Software Engineering Do you have a business idea for an AI solution ?
