Arem

Web3 technical writer and builder.

I write about self-custody and DAO tooling, and I build products end to end, from architecture to shipped code.

About

How I work.

Short version. The long version is in the writing section.

I write about Web3 infrastructure: multisig wallets, self-custody, and DAO tooling. Most posts start as a problem I hit while building, worked through until it is reproducible in a tutorial.

I build products end to end, from architecture to shipped code. Development is AI-assisted: agents handle the mechanical work while I own the architecture, the product decisions, and the review.

Current focus: Propeida's exam prep platform, and a series of tutorials on wallet infrastructure.
