      <h1>Dr. David O'Brien</h1>
      <p>Applied Scientist II in the Next-Gen Developer Experience org at AWS. I defended my Ph.D. entitled <b>"Data-Driven Techniques for Identifying and Automatically Repaying Technical Debt"</b> at Iowa State University under the advisement of Dr. Hridesh Rajan.<br><br>
      I am passionate about building intelligent developer tools and advancing the science of software engineering. My expertise spans agentic AI, static analysis, code generation, and large-scale pattern mining. I have contributed to research and product development at AWS and Apple, with a focus on leveraging machine learning and program analysis to automate and improve the software development lifecycle. My work is published at top-tier software engineering conferences and aims to bridge the gap between research and impactful developer experiences.</p>
