Daniel Oyasodun

Clinical Database Developer | Software Engineer | Data Analytics

Building reliable clinical data systems, automating validation workflows, and developing software that transforms complex data into actionable insights.

Powering Clinical Research Through Software

I'm an Associate Clinical Database Developer at Regeneron Pharmaceuticals and a Computer Science graduate from NJIT with a passion for building reliable software and high-quality clinical data systems.

My work focuses on developing and validating clinical databases in Medidata Rave EDC, designing eCRFs, implementing edit checks with Medidata Custom Functions, supporting UAT, and ensuring clinical trial data meets regulatory and quality standards. I also enjoy applying Python, R, SQL, and SAS to automate workflows, validate data, and solve analytical problems.

Outside of clinical development, I enjoy building full-stack applications, experimenting with AI-powered tools, and working on sports analytics projects that combine machine learning, data engineering, and visualization.

Away from the keyboard, you'll usually find me watching the Oklahoma City Thunder, Tottenham Hotspur, or the New England Patriots.
