What it is

Montu Mia is trying to keep a video site alive. Each chapter is a problem he hits, load balancers, caches, CDNs, the trade-off that didn't fit on the first slide. I publish it as a site and a LinkedIn newsletter. Bengali is the default. English lives under /en. Email goes out through AWS SES. The site list has 1,100+ subscribers. LinkedIn has 2,600+. OG images are generated per chapter. The reading UI is Fumadocs and MDX.

What it does

  • Chapters in Bengali, with English chapter by chapter
  • Email newsletter through AWS SES and React Email
  • OG image per chapter
  • Dark and light reading UI
  • Untranslated pages fall back to Bengali

What was hard

  • SES plus React Email without turning into a deliverability hobby
  • OG images that still look like the chapter
  • LLM translation that kept Montu's jokes, then a lot of hand edits
  • Making Fumadocs read like a book, not a docs site

What happened

  • 3,000+ subscribers across the site and LinkedIn
  • 1,100+ on the site list, 2,600+ on LinkedIn
  • 30,000+ unique visitors, 125,000+ page views
  • 147 GitHub stars
