Product Overview
The system, which was operating on-premises, faced challenges such as aging infrastructure.
The project started with rebuilding the store management system on an AWS foundation, followed by migrating consumer-facing systems.
Subsequently, a project to revamp the BFF and Backend was initiated.
Role in the Team
In the Scrum framework, I was responsible not only for development but also for design, implementation, testing, and release tasks.
I proposed improvement plans such as cost reproduction within limited resources.
Additionally, I caught up on domain-related books and aimed to propose specifications and develop features with greater impact.
Specific achievements include:
- In the revamp project, the IaC of the infrastructure enabled quick replication of development environments.
- Cost reduction using FargateSpot.
