I'm Bunyod, a solo dev in Tashkent. I'm building Replyra: AI agents that answer a business's customers in Telegram, Instagram and on its website, in Russian and Uzbek. When a question gets hard, the agent hands it to a human. Before this I shipped StatementSheet (bank PDFs to Excel) and Vendlingo (Etsy listings for EU shoppers). I'll post what breaks and how I fix it.

my carb counter was sending every meal photo at full size, 2 to 4 mb as base64, to storage and to the ai. there was a resize function in the code. nothing called it. what's the best dead code you found that would have fixed a real problem?

german writes stacking ring as one word, Stapelring. a translator that splits it into Stapel Ring reads fine to me and wrong to a german buyer. so my etsy listing tool translates every result back to english and lists what changed.

the default wait for an airline's reply in my flight delay checker is 62 days. two months at their longest is july plus august, so the date it prints can never come early. the uk regulator uses 56, so it gets its own row in the table, and a test pins the 62.

Russian CSV from Excel wouldn't upload on prod. Worked fine on my laptop. Prod ran Bun 1.3.14, which can't decode windows-1251. My laptop had 1.4, which can. Worse, a site in that encoding got saved as "����" with status Ready. Wrote the decode table myself. Checked it inside the prod image, not locally.

Every click between pages on my site was a 404. Only in prod. My 404 rewrite rules were also catching /ru.rsc, the request Next.js makes on Vercel when you navigate. Locally next start never does that. Now after any routing change I curl prod with RSC: 1 and wait for a 200
