I'm Dennis Tien Donaghy Sparks, an AI/ML engineer with hands-on experience building generative AI solutions, cloud and hybrid systems, and end-to-end ML pipelines. I enjoy turning research concepts into prototypes, integrating LLМ components into existing systems, and collaborating with teams to trade off performance, reliability, and speed in clear terms. I thrive on designing practical architectures and shipping tangible results for complex problems. Recently I design and implement ML/data systems, pipelines and workflows across GCP, Databricks and AWS, building LLМ-driven applications with LangChain, LlamaIndex, Vertex AI and open-source models. I work on RAG-style data flows, embedding models, and CI/CD-enabled deployments with Terraform IaC, monitoring, and governance to keep solutions robust and scalable.…I'm Dennis Tien Donaghy Sparks, an AI/ML engineer with hands-on experience building generative AI solutions, cloud and hybrid systems, and end-to-end ML pipelines.
