PBSSD Project (2023.03 ~)

Development of PBSSD using Storage Disaggregation. Developed a Product-Based Software-Defined Storage (PBSSD) system utilizing Storage Disaggregation technology. Concentrated on the development of the Orchestrator, emphasizing on resource allocation and management, task scheduling over IO operations.

Tech Stack: Programming Language: Golang, Python. Frameworks/Libraries: Docker SDK.

Secondary Role: DevOps.

CI/CD Pipeline Setup: Configured and maintained CI/CD pipelines for intra-network and extra-network using Github Actions.

Server Room & Development Environment Management: Managed the server room for the intra-network and supported the development environment, contributing to the improvement of team’s development productivity.

Tech Stack: Tools: QEMU, GitHub Actions.

PoseidonOS Project (2021.09 ~ 2023.02)

Key Project: PoseidonOS. Spearheaded the development of PoseidonOS, a next-generation storage solution employing Storage Disaggregation technology, transcending traditional JBOF architectures by introducing metadata management. Delivered virtualized block devices offering critical features such as capacity elasticity, performance throttling, and data protection (RAID), transparently provided to customers. Role focus: Focused on the development of metadata management and journaling mechanisms, establishing a robust foundation for data tracking and recovery, significantly enhancing the system's reliability and operational efficiency. Subsidiarily managed the server room operations ensuring optimal server performance and maintenance.

Tech Stack: Programming Language: C++, Python.

Frameworks/Libraries: Protocol Buffers (Protobuf). Tools: GDB, Git.

Technical Details: Journaling: Developed a robust journaling mechanism to ensure data integrity and facilitate recovery procedures. Metadata Management: Designed and implemented an efficient metadata management system to enhance data retrieval and management processes.
