Technical Architecture Diagram Design

I need a set of clean, professional-looking technical architecture diagrams that convey both the bird’s-eye view and the in-depth layer breakdown of my system. The work must be produced in draw.io so I can maintain the file later; exports in PNG or PDF will be helpful for quick sharing... (Budget: $30 - $250 USD, Jobs: Architecture, Data Architecture, Draw.io, Technical Drawing / Tech Pack, Technical Writing)
