•Owned the core low-level design for a key workstream under an SVP-level initiative to improve inbound delivery precision and reliability; authored designs spanning 5+ interconnected systems, facilitating scalable on-time-delivery enforcement and reducing downstream processing delays across the network
•Improved delivery-window accuracy and compliance reliability across 97% of the inbound network by integrating carrier transit-time data and shipment-level capacity validation into the existing computation framework
•Enabled a multi-million-dollar shift from fixed rates to dynamic, science-driven pricing for seller shipping costs by developing a new AWS-Lambda-based pricing service and refactoring backend systems to support real-time markup-rate decisions; designed the BI export component processing 20M+ weekly markup records
•Unblocked a critical dependency for the launch of an international retail domain (Amazon.ie) by delivering infrastructure mapping and commercial-invoice generation workflows, supporting a $1MM/day revenue launch
•Reduced onboarding time for new transportation-compliance use cases from multiple weeks to <2 days by implementing an automated workflow orchestrator and centralized configuration store for templates, replacing a legacy manual process
•Drove operational excellence through on-call participation, contributing to CloudAuth migration, mature host cutovers, and migration to modern load-balancer infrastructure, improving authentication resilience and service stability
•Led Agile team ceremonies (daily stand-ups, sprint planning, retrospectives, and demos) and managed sprint workflows and team backlog in Asana/Jira to maintain clear priorities, surface blockers early, and improve team delivery cadence
•Mentored two junior engineers on communication, prioritization, and time management, and supported new engineers in rapidly ramping up to full development productivity through guided onboarding and hands-on coaching
