MTA (Mail Transfer Agent) Renewal Project

Overview

I participated in a project to revamp the Mail Transfer Agent (MTA) as part of a broader initiative to improve spam detection and modernize the email transmission system. The MTA was composed of a Java-based web application and a Go-based backend service, and I was involved in the development of both.

• In implementing new features, I focused on designing for maintainability, readability, extensibility, and ease of unit testing.
• During code reviews, I worked to improve quality from the perspectives of performance and clarity.
• Throughout the development process—from implementation to testing—I consistently looked for opportunities to enhance performance and code quality, and proactively made suggestions for improvement.
