• Decoupled core creative schemas serving 280K+ ad creatives, enabling independent data evolution across teams and improving scalability of mission-critical bidding pipelines.
• Built and deployed a migration framework ensuring backward compatibility and zero-downtime rollout, leveraging Go, gRPC, and config-driven staged deployment mechanisms.
• Optimized in-memory data representation for high-volume creatives, achieving ~1 GiB memory reduction and preventing further growth as dataset scaled.
• Designed and implemented a wrapper-based schema abstraction to safely support both legacy and new creative structures during migration.
• Collaborated with 3+ cross-functional teams to test, validate, and roll out the new architecture, accelerating adoption and reducing migration risk.
• Gained hands-on experience in distributed systems, schema design, performance benchmarking, and safe rollout strategies in production environments.
