Johnny moves so fast he asks an AI for permission before he finishes typing his own thought, blink during his standup and you'll miss three launches and a pull request that already auto-merged.

Revived his very first Perplexity project, an AI stock screener, and shipped it to production, improving from ~50% LLM reliability two years ago to ~99% today; plus led major infra improvements powering Deep Research and Computer.

To remove friction between people and complex information by building fast, reliable AI infrastructure and agentic tooling that lets computers take on the hardest tasks so humans can focus on higher-leverage work.

Values speed, pragmatic experimentation, and measurable reliability. Believes in shipping early and iterating, automating context switching, empowering developer experience, and letting data guide decisions over dogma.

Rapid product- and infra-level execution, deep technical chops from HFT and competitive programming, strong focus on reliability and instrumentation, and the ability to rally engineering teams to ship complex features fast.

Can prioritize speed over polish or community storytelling, occasionally terse in public engagement, and may under-index on audience-facing content (low tweet volume relative to impact) which slows personal brand growth.

Grow on X by translating infra wins into accessible narratives: post short explainer threads (before/after metrics, root causes, fixes), share lightweight demos/screenshots or short videos, run occasional AMAs/Spaces about agentic tooling, spotlight team stories and post-mortems, engage frequently with replies, and pin a signature thread called something like “Build with Johnny” that bundles lessons, code snippets, and product milestones.

Fun fact: Johnny's very first project at Perplexity was an AI stock screener when LLMs were ~50% reliable, today it's back in product at ~99% reliability. Also, there's an unofficial office protocol he mentions: ask the AI before asking another person to reduce context switching.
