James Ahn

Developer

Years of experience: 20

James worked as CTO at CyberRenassance Inc. (Japan) and later as a representative of MHR and DeepNumbers. He served as a consultant to the NIA Platform, a technical advisor to the National Computing & Information Service, and an advisor to Cloud for the Korean Agency for Technology and Standards.

Through his past achievements, he had displayed the ability to creatively solve limitations in existing system designs, to ensure high availability and high performance of platforms that he had worked on. James is passionate about new technology and has been always on the front of revolutionary changes such as cloud, machine learning, and now, blockchain.

Key Achievements:

Developed a big data platform for the National Assembly Library (the library manages and preserves the National Assembly records), which stores data of academic materials and books which outsiders can access regardless of the original data structure. The service includes big data abstract module that has two core modules including and user defined analysis model module.

Designed an algorithm trading system, which collects and analyses stock market data, generating alpha for traders.

Ensured high availability of a SaaS platform, developed using a method called Essence, as a governmental research project. James used a micro service architecture to ensure that the SaaS was always ready for use worldwide.

Used machine learning and energy consumption models to monitor and follow resources used by the Cloud DVFS system, to understand power consumption needs in real-time. It was a government research project to understand the adequacy of computing resource and structures the computing zone extract maximum efficiency from the power consumed.

Built a Cloud provisioning system, using YAML to avail computing resources automatically based on the user’s needs. It was designed to be robust, and depending on the hardware environment, the system can handle thin provisioning, ensuring high performance in the VM.

As part of a government research project, James designed a big data system which can stream large volumes of data in real-time. Hadoop was unable to handle big data processes in real-time, hence James designed a creative method to enable abstract data to be streamed in real-time, by creating a data source which is then transmitted to an external system. The external system can then use the data source as a database, enabling the development of application system with ease.

Built a Virtual Desktop Infrastructure environment using XEN. Guest OS automatically creates necessary resources after window provisioning and automatize environment setup. As it supports powershell, it can make necessary options and various setups depending on the specifications required. The high performance infrastructure can create the necessary environment within one minute using the master-template.

Implemented a system to improve efficiency of cloud resources in a national college, so that big data students can avail themselves to the resources needed. Computing resource scheduling is important because various big data software programs are operated in cloud. To solve this issue, James developed a Smart Resource Scheduler that selects Host Machine based on the usage of three resources such as Network, CPU and Memory.

In another government research project to increase energy efficiency, James used real-time metering machine in electronic devices used the office to monitor whether devices were being used. This was measured by the changes in electricity consumption of the devices. The system built by James would then turn enable/disable devices depending real-time data.

As part of the government research project, James developed a web analytics service, which collects and analyzes various logs that users create on web services and understand the browsing patterns and their interactions with the websites. The core idea of the technology is to create special ID of users, by detecting the movement of the users and detect the movement between pages with delicate timer.
