Thanks @MATHEW-SHERENI , and sorry this sat so long. Good writing here, but I want to redirect it.

• The write-up is a product overview, not a blog post. It describes what MaterialDerailleur is and does, which is useful, but nothing in it reports anything that actually happened while building it.
• "Implementation Insights" says designing around real workflows matters and onboarding matters. Both true of every project, so a reader comes away knowing nothing specific about this one.
• Same with the architecture section. It names React, Express, Prisma, and Postgres without saying why we are using any of them.
  Recommendations:
• <ove the good descriptive sections into docs/projects/md/about.md. That page is thin and this would genuinely improve it.
• Bring the diagrams with you. architecture-overview.png and donatedItemDetails.png are committed here but never referenced, and both belong on the product page.
• If you want an actual post, pick one thing that happened. The item status model is the interesting one, since you mention items get damaged, repaired, moved, mislabeled, duplicated, and reassigned. Barcode/label printing against real printers would work too, or anything BWorks made you change. A story should be about an event or an accomplishment. If you do a site tour or get registered as a DPG, that's newsworthy. As for writing, target Half this length and talk to me before you draft to work through story ideas.

On the tech lead updates, those are fine and still accurate for fall. Pull them into their own PR and I'll merge it this week so you're caught up with everyone else. Two fixes first:

• Drop the prior Tech Lead field. No other page has it. Move Supraja and Jacob into the Developers list as (alumni, prior tech lead).
• Nothing in src/data/people/ got updated. Supraja and Jacob need to move to prevTechLeads.json, and you need to be in currentTechLeads.json.

Cleanup, wherever the content ends up:

• .idea/.gitignore shouldn't be committed. Drop it and add .idea/ to .gitignore.
• The blog folder name has a U+2011 non-breaking hyphen in it instead of a regular one, between "Material" and "Derailleur". Invisible in most editors, breaks shell globbing. Rename to plain ASCII. Your slug is explicit so the URL doesn't change.
• The captions on donatedItem.png and donatedItems.png look swapped.
• The official spelling is MaterialDerailleur, one word. The post uses "Material-Derailleur" throughout, and about.md already uses the canonical form.
• "more time-serving their communities" should be "more time serving".
• The date: line you added to the Mithridatium post is a fair fix but unrelated, and I have other work in flight on that post. Pull it out.
