Specializing in TCP/IP, Infrastructure, and Operating Systems

About

I love to build software that is easy to maintain and use, and that solves a problem. I am very fond of learning about operating systems, networking, system design, and cloud technology, and I love to read books. My past professional work includes developing software platforms for cutting-edge ASIC transceivers.

Some enjoyable books:
• Designing Data Intensive Applications
• Operating Systems: Three Easy Pieces
• TCP/IP Illustrated Vol. 1
