   Mohanakrishna Vanamala Hariprasad — résumé
   Design concept: an engineering drawing. The page borrows the vocabulary
   of a blueprint / architectural drawing set — a title block, dimension
   lines, revision marks, drafted lettering — because the subject is a
   systems engineer who spends his working life drawing exactly that kind
   of diagram. Durations below are drawn to scale, the way a real drawing
   would render a timeline.
