Featured Author

Kat Cosgrove is a chronic early-adopter of new technologies and a real-life cyborg. Her professional engineering background is in web development, IoT, and programming education, but today she's a Developer Advocate for JFrog. She loves finding creative solutions for hard problems, especially if they're a little hacky. When she's not building demos or at a conference, she spends her time gaming, watching e-sports, and working on useless but entertaining side-projects. She also volunteers with area non-profits geared towards getting more women and other underrepresented minorities into tech.
