Owned API design and modernization strategy, leading incremental legacy migration for a high-volume digital marketing platform.

• A high-risk legacy rewrite was addressed by evaluating feasibility and proposing an incremental modernization strategy, preventing a massive project failure.
• Tight backend constraints were addressed by designing a two-tier frontend architecture, separating user experience iteration from legacy system limitations.
• Brittle internal integrations were addressed by designing and building an API Gateway, safely exposing selected internal services through secure interfaces.
• Operational and maintenance risks were addressed by introducing code quality and security tooling, improving platform reliability.
