Boris
Boris is the founder of Claude Code, an AI-powered programming assistant tool for developers developed by Anthropic. He has long focused on the intersection of AI and software engineering, working to apply large language model capabilities to code generation and development workflow optimization. He views AI's transformation of the software industry as having profound historical significance, comparable to the impact of the Gutenberg printing press on information dissemination.

Boris believes he is still better than the model in two areas—product intuition and distributed system design—and expects the model to be 'pretty good' in these areas by the end of the year.
Since March, Boris has consumed 8 billion tokens.
Boris now does most of his coding work on his phone.
After Boris gave Claude Code a single instruction, the model ran for hours, consumed millions of tokens, and produced four PRs that reduced CI time by 50%.
About 30% of Boris's code is written by loops, and on good days it can reach 100%.
Boris described dynamic workflow as the 'fourth scaling factor' after model size, data volume, and training compute.
Since the release of Opus 4.5, 100% of Boris's code has been written by Claude Code.
This year Boris submitted 1,700 PRs, adding about 400,000 lines of code and deleting 250,000 lines.
According to Boris, approximately 80% of Anthropic's technical staff use Claude Code on a daily basis.
Boris recommends that beginners start with codebase-based Q&A rather than modifying code right away.
