Project History
ISP Management System (2000)
Designed and developed an entire ISP IT infrastructure, including authentication, authorization, accounting, dynamic routing, traffic management, monitoring, online email, and billing. The system was based on MySQL with a C++ back end, Java/Tomcat 3.0 front end, and FreeBSD 3 with Cisco IOS 11 as the platform.
Interactive Voice Responder System (2005)
Participated in the design and development of an IVR system (embedded C++ with JNI). The system connected directly to the telco's digital T1 lines, playing back voice prompts, receiving DTMF responses, and interacting with the business logic (Java) via JNI.
Online and Kiosk Check-in (2015)
Online and kiosk check-in are applications used by passengers for self-service check-in via the web or at the airport. I was the architect of both applications, which are still used today by millions of passengers worldwide. The kiosk check-in is especially challenging due to the differences in the CUSS spec implementation by different vendors and a wide variety of available bandwidths.
TripPlanner (2017)
TripPlanner is a high-performance ticket pricing system. I was brought in as a consultant/architect to improve performance and stability. The performance improved by over 40% in the first two weeks, mainly as a result of better memory allocation and an upgrade to C++14. I also implemented a distributed mesh protocol for synchronizing in-memory caches.
