Owned and evolved core backend systems in the Order Management and Shipping domains, supporting both freight and parcel workflows.

Led the redesign of the shipping label purchase flow by separating synchronous and asynchronous paths, enabling the platform to scale to 400k+ labels/day while improving warehouse latency and reliability.

Designed and operated event-driven systems using Ruby on Rails and GCP Pub/Sub, with explicit handling of retries, idempotency, and production failure modes.

Resolved multiple production incidents in asynchronous workflows by introducing stronger state guarantees and concurrency controls, significantly reducing DLQs.

Delivered time-sensitive features for large enterprise customers under tight deadlines by prioritizing minimal, reversible designs over risky large-scale refactors.

Built and maintained internal and external APIs for shipment lifecycle management, including webhook-based integrations with carrier systems.

Collaborated closely with senior and principal engineers on architectural decisions, constructively challenging designs using performance analysis and system behavior under load.

Participated in on-call rotations, owning incident response, root cause analysis, and long-term reliability improvements.
