What I'm looking for

I’m looking for high-ownership remote startup environments where engineering directly powers operations teams, combining product ownership with hands-on building, reliability, automation, and close collaboration with non-technical users.

Hands-on full-stack engineer and tech lead with 9+ years of Python experience and a track record building production software for logistics, operations automation, internal tooling, real-time workflows, cloud/data workflows, and 3PL integrations. Owns products end-to-end from requirements and data models to backend APIs, React/Angular interfaces, async queues, WebSockets, databases, Databricks, Azure Cloud, AWS, and production support.

Built systems that enable a 4-person team to manage 200+ weekly appointments, process sub-second scanning events, and control inventory for 20+ vendors across multiple locations.

Strong fit for high-ownership remote startup environments where engineering directly powers operations teams.
