Adriel Martins
@adrielmartins
Senior ML Engineer specializing in production LLMs, RAG, and scalable MLOps.
What I'm looking for
I am a Senior Machine Learning Engineer with an MSc in Computer Science (expected 2025) and a strong foundation in statistics, dedicated to designing and deploying production-grade AI systems combining LLMs, computer vision, and multi-agent automation.
I have delivered measurable impact across logistics, finance, and startup environments — from reducing response times 50% with multi-agent RAG systems to accelerating video-LLM inference 5x using PyTorch, HuggingFace, and AWS infrastructure. I build end-to-end architectures covering data ingestion, embeddings, vector databases, monitoring, and scalable deployment.
My work emphasizes operational efficiency, production-ready MLOps, and robust model monitoring; I focus on creating scalable pipelines and automated systems that improve analyst productivity, reduce downtime, and drive revenue growth for enterprise clients.
