Flex Tech Stack

Tech-driven logistics platform for large-item delivery and storage

Transportation, Logistics, Supply Chain and Storage Aventura, Florida 201–500 employees Founded 2022 Privately Held

Flex operates a logistics platform purpose-built for moving and storing large items—a fragmented industry with complex workflows and offline-heavy processes. The stack (Node.js, Python, FastAPI, PostgreSQL, Kafka, GCP) reveals a backend-first architecture handling asynchronous delivery workflows; the active migration from Angular to React and parallel adoption of React Native signals a shift toward mobile-first user experience. Current hiring is skewed toward principal engineers and senior IC roles with a data director—indicating investment in observability, demand prediction, and platform scalability rather than headcount expansion.
