Full-Stack Serverless Architecture-Based
High-Availability Platform Operations & Optimization

This project was undertaken to stably operate the web services and data collection environment of Catch Fashion, a global luxury platform, and to enhance the system for business expansion.

TOSKY fully adopted the AWS Serverless Framework, building and maintaining a complete serverless stack spanning Lambda, API Gateway, and DynamoDB, achieving elastic infrastructure that flexibly responds to traffic changes.

In particular, the development and performance optimization of crawling models — a core platform asset — were conducted in parallel. Bottlenecks in the large-scale data collection process were resolved through asynchronous messaging via SQS (Simple Queue Service), ensuring system stability.
A robust TypeScript-based code base was maintained to maximize development productivity and maintenance convenience, while automated infrastructure management through IaC (Infrastructure as Code) simultaneously achieved operational cost reduction and system availability maximization.
