Inventory Management System
Backend platform powering live retail operations across multiple client environments.
Inventory data was out of sync between warehouse operations and live retail systems, creating manual reconciliation overhead, operational risk, and recurring data integrity issues across multiple client accounts.
Python and TypeScript backend with a REST API design and validation layer. Focused on production reliability, multi-client deployment, and a structured approach to reducing data inconsistencies. Owned the full delivery lifecycle from requirements gathering through deployment support.
UX prototyping driven by direct client feedback loops. Translated complex operational workflows — inventory counts, sync states, reconciliation status — into clear interfaces that retail staff could act on without technical knowledge.
Improved platform reliability in live production environments. Reduced data inconsistencies across client accounts. Supported zero-downtime expectations for retail operations and enabled the team to scale the platform to additional clients.
