Rockstar🎓
Top SchoolDoug Farrell is a Principal Software Engineer with over two decades of cross-industry experience, currently building Python and FastAPI services at Rectangle Health and specializing in AWS-based deployments with CDK. He combines deep backend expertise—particularly in Python—with practical full-stack experience from hands-on work on realpython and Flask projects, plus front-end templating and CI fixes. Doug excels at leading teams, teaching new technologies (including adult education and STEM outreach), and translating legacy embedded and high-performance real-time requirements into efficient web and cloud systems. Comfortable mentoring and documenting complex systems—he’s the author of The Well-Grounded Python Developer—he also intentionally focuses on modern stacks and avoids roles in languages he no longer maintains, like Java and older C/C++ work.
