Boris Cherny's 10-15 Parallel Session Pattern: One-Person Engineering Team via Worktrees + Browser Sessions

ShareUHack·medium signal

Boris Cherny (Claude Code creator) shared a workflow now widely adopted: run 10-15 Claude Code sessions simultaneously, each pushing forward on a different task independently. The practical recipe is 3-5 git worktrees (his direct recommendation) plus additional browser-based sessions for non-coding tasks. Most developers plateau at 4-6 effective parallel sessions before context-switching overhead exceeds gains. Agent Teams push the ceiling to ~8 agents because agents coordinate with each other, reducing human oversight needs.
