Why I built Monk Mode

I built Monk Mode because I kept losing entire workdays to a feed I opened for "just a minute."\n\nThe app is not about being dramatic. It is about making the default path less slippery.

Backpressure in document pipelines is an architecture problem first

When document teams talk about reliability, extraction quality usually gets the spotlight first. That makes sense, but another issue becomes visible very quickly in real workflows: backpressure.

When I started building SolBundler, the main problem I wanted to solve was simple: sniper bots were destroying pump.fun launches. The moment a token goes live, bots buy block 0 and dump immediately. Developers lose control of their own launch. So I built SolBundler — a tool that lets you deploy a t...
