Pagewala, my AI sales agent for Facebook sellers in Bangladesh, is live. Developers have installed my Claude Code dashboard 9.4K+ times. By day I build a multi-agent SEO engine at Nordivo. Before that, I led the platform team behind 100+ services and 100M+ requests a day.

An AI sales agent for Facebook Page sellers in Bangladesh that handles customer conversations, product questions, and order capture through Messenger.
An image service rendered HTML in headless Chrome and needed 10 servers to keep up. No rewrite: I split the work across browser tabs behind a bounded promise pool, so Node's thread pool could finally use every core.
400 → 100 min per 100K images · 10 servers → 1 · 16 → 6 GB RAM
A zip step pinned an 8-core machine at 95% CPU. Before tuning anything, I asked the team downstream. They unzipped everything on arrival, so file size never mattered. Switching LZMA2 for Deflate traded size nobody needed for CPU we did.

In Pagewala the model talks, but the server decides. Prices come from the database, stock moves in a transaction, and three layers stop duplicate orders. An AI that sells has to be boring where money is involved.
