Available for Contract Work – Generative AI & Machine Learning
I’m Dr. Alan F. Castillo, a Generative AI Data Scientist, Architect, and hands-on engineering practitioner available for contract engagements supporting enterprise organizations, federal agencies, and technology-driven teams.
I specialize in helping organizations design, build, deploy, and operationalize real-world AI systems that deliver measurable value—not just strategy decks or prototypes that never reach production.
If your organization needs a senior-level AI architect and practitioner who can bridge strategy, architecture, and implementation, I would be glad to help.
