Barry A. Feigenbaum, Ph.D., now retired, has decades of professional software engineering experience. During his career, he has worked for major industry-leading companies, such as IBM and Amazon, and most recently at Dell where he was a Senior Principal Software Engineer. He has worked on mainframe and midrange servers and many applications for personal computers. He has developed software products, such as assemblers and word processors for multiple hardware architectures, in many key industry languages such as various assemblers, FORTRAN, PL/I, C/C++/C#, Python, JavaScript, Java, and most recently Go. He has extensive experience in the full software development life cycle. Most recently, he was a lead on teams developing mission-critical microservices, most often written in Go and C++, that operate in large, clustered environments, often managed by Kubernetes.

He led the early development of the LAN support inside Microsoft Windows (he defined the SMB protocol that is the basis for both the CIFS (Windows) and the SAMBA (Unix and Linux) technologies). He has served as a software tester, developer, and designer as well as a development team lead, architect, and manager on multiple occasions. He was a key contributor as a developer, architect, and manager to several releases of PC-DOS (also MS-DOS) and OS/2. In these roles, he worked extensively with Microsoft on joint requirements, design, and implementation.

Dr. Feigenbaum has a Ph.D. in Computer Engineering with a concentration in object-oriented (OO) software design and a masters and bachelor degree in Electrical Engineering. He has published multiple articles in technical magazines and juried journals. He has coauthored several books on IBM PC-DOS. He has spoken at numerous technical conferences, such as JavaOne. He has served on industry standard bodies. He has taught multiple college-level courses on data structures, software engineering, and distributed software as an adjunct professor at several universities. He has over 20 issued US patents.

He is widowed, has one son, and lives in Austin, TX.
