Journey
As a Senior Software Engineer, I was responsible for Labels, Manifests, and Refunds APIs used by Shippo customers. Labels are the core product that Shippo offers. During my time in this role, I built pipelines responsible for billions of dollars in reconciliation and reporting, advanced alerting for critical systems, and reliability infrastructure such as a circuit breaker for our most active API integration. I also optimized our main CICD pipeline to reduce its runtime by 66%.
As a Software Engineer, I was responsible for maintaining the 100+ API integrations Shippo has with carriers. I introduced new carrier integrations unlocking millions in revenue. I wrote internal tooling to migrate customer accounts. I also worked on core infrastructure for local rating, developing major parts of an engine for automated updates for millions of rates.
