Gary Dahnke
@garydahnke
Early‑career AI practitioner developing skills in prompt design, data labeling, and model testing, with a long software background.
United StatesWhat I'm looking for
I’m actively building my capabilities in AI through hands‑on work with prompt design, data labeling, and model testing, supported by recent certifications in AWS AI, Azure AI Fundamentals, and Python data analysis. I enjoy the structured, detail‑oriented nature of AI evaluation and the challenge of improving model behavior through clear instructions and high‑quality data.
My career foundation comes from more than three decades in software development, release management, and application support across mainframe, distributed, web, and cloud environments. I’ve spent much of that time diagnosing complex issues, validating data flows, coordinating across teams, and ensuring stable, reliable application delivery. Those experiences taught me to think analytically, document clearly, and work with precision — all of which translate naturally into AI‑aligned workflows.
As I move deeper into AI operations, I’m applying my background in SQL, Python, automation, and data quality to modern evaluation and labeling tasks. I’m looking for opportunities where I can contribute to prompt iteration, model testing, and data‑centric processes while continuing to grow my skills in AI‑assisted development. I’m motivated by roles that value reliability, thoughtful analysis, and a strong foundation in software delivery.
