Sergey Moloman is an AI product engineer who builds Roleplay, a voice AI practice customer for sales teams, and tools for coding agents such as Brow and co-od.
Sergey works alone and ships whole products: web apps, native Mac apps, command-line tools and Claude plugins.
Most of his work is voice AI for sales teams. Roleplay lets reps practise calls against an AI customer built from their own company website, and he has built production voice AI and a call simulator for a call center working in three markets.
The rest are tools for AI coding agents such as Claude Code and Codex: Brow puts their permission requests in the MacBook notch, co-od lets a team and its agents work in shared rooms, Dragoman localizes apps and checks every translation, and ai-sec decides whether to allow, review or block what an agent does.
He writes about what he tests and builds on X, including model comparisons on real tasks and the bugs that cost him a day.
