The desktop app runs locally on a client's network, with an opt-in cloud layer for data sharing hosted on AWS. You'll work on FastAPI backend services, PostgreSQL (encryption, access control), and handling of large object files with AWS S3 integration for encrypted, region-matched cloud storage. Front-end work uses Node.js/React, building and maintaining the desktop UI. This is a contract role with potential for ongoing work based on fit.
