Client is a multinational science and technology company focused on Healthcare, Life Science, and Electronics.

Client pain points in the project:

- The TLC device software requires an update to be GxP compliant.

- The client lacks the technical resources necessary to implement changes in the software

Scope of the project:

• FE: We will build upon the existing React frontend to implement the new GxP interfaces (e.g., login, e-signature, admin panels) while preserving the core scientific and analysis workflows your team already uses.
• BE: We will preserve the existing Python backend, which contains the core scientific IP. Our work will focus on adding new, parallel GxP-compliant services (for auth, audit, etc.) that integrate with the main application.
• Data & GXP Storage: This is the one new architectural component. As recommended by the audit, we will replace all insecure JSON files with a lightweight, industry-standard SQLite database. This is the foundation for secure user management and the immutable audit trail.
• Web Server: We will maintain the current, web server configurations. This is a standard and high-performance setup for serving Python and React applications.
• Opearting system: We will continue to use the existing hardware platform. Our "Stabilization" scope directly addresses the audit's findings by automating the build process for this OS, making it traceable and auditable instead of a "black box."
