Comprehensive System Diagrams Needed

I’m putting together full documentation for a new software project and need four clear, well-structured diagrams created entirely in Draw.io:

• Architecture diagram
• High-level software (component) diagram
• Entity-Relationship (ER) diagram
• Use-case diagram

All four should follow standard industry conventions; no proprietary frameworks or niche notations are required. I don’t have any existing sketches, so you’ll be starting from a blank canvas. I’ll supply a short written brief outlining the system’s modules, data entities, and user stories once we begin, and I’ll be responsive to clarify details quickly.

Deliverables are the editable Draw.io files plus exported PNG or SVG versions ready to drop into a report. I’ll consider the job complete when each diagram:

1. Reflects the scope and relationships described in the brief.
2. Uses consistent, readable labeling and color coding.
3. Is delivered in both editable and image formats with no layout issues.

If you’re comfortable designing clean, standards-based diagrams from scratch, I’d love to work together.
