Rubens Zimbres

Senior Machine Learning Engineer, Ph.D.

šŸ”­ Iā€™m currently contributing for OWASP Top 10 for LLMs and also in Langchain and Generative AI studies with Google Cloud Developer Experts

šŸš€ Iā€™m learning cybersecurity in the intersection with A.I.

šŸ‘¾ About me šŸ‘¾

I am a full-stack ML Engineer, certified Google Cloud Data Engineer and Google Developer Expert (GDE) in Machine Learning and Google Cloud Platform, AWS Certified Cloud Practitioner and AWS Certified Machine Learning - Specialty. I'm experienced in Machine Learning and Deep Learning algorithms with focus on efficiency, scalability and strategic insights. I work with Machine Learning, Deep Learning, Transfer Learning, Natural Language Processing, Generative AI, LLMs, LangChain, RAG, pgvector, LoRA and Recommendation Systems.

I've been working with chatbots and retrieval/search solutions in the last year, incorporating Generative AI in the projects, open source (Mixtral, LLaMA) and not (Vertex AI, Gemini models). I also know how to fine tune LLMs with LoRA and QLoRA, quantization, and I know how to develop and deploy Retrieval Augmented Generation solutions RAG, with LLaMA index and also with Langchain (conversation with memory), using embeddings.

I am experienced in Python, Wolfram Mathematica, PySpark ML, MLFlow, SQL, Kubeflow and NetLogo. I'm very comfortable with Linux environments. I have extensive training and experience in Google Cloud solutions, including Vertex AI, MLOps and Generative AI, GCP architecture, security, cost planning and services related to cybersecurity of cloud environments. I specialized in cost-efficient use of the cloud. I am CompTIA Security+ certified.
