Available to hire
Hi, I’m Chester Hamby, a Senior Software Engineer with 12+ years of experience delivering end-to-end ML and software solutions across healthcare, legal, and enterprise domains. I specialize in Large Language Models (LLMs), NLP, computer vision, fine-tuning, RAG, and RLHF, and I enjoy turning complex data into practical, scalable AI applications.
I build robust backend microservices (FastAPI, Flask), interactive front-ends (React, TypeScript), and data pipelines (Kafka, Spark, Airflow) deployed on Kubernetes. I’m focused on HIPAA-compliant, high-availability AI systems and collaborate closely with product teams to deliver value for customers.
