I'm Bobby Hall Jr, an engineer with 8 years of experience building full-stack products, agent systems, and engineering intelligence that turns complex context into useful outcomes.
Products exploring how people and AI work together, from a daily game about outsmarting an AI to systems that give AI enough context to do real work.
Trick the AI into telling you the secret.
A new AI to crack every day. Meet the character, pick your moves (Ask, Plant, Impersonate or Decode), pop the locks, and get them to spill. Solo or with a friend. Free, no signup, about 2 minutes.
Give recurring work a real owner.
Roster lets teams hire focused AI employees with a clear role, trusted company context, and permission to use real tools. Work ends in a finished deliverable, with human approval before important actions.
Software should explain itself.
Helix connects code, decisions, incidents, ownership, and AI-generated changes into a living Engineering Graph, so teams can understand why software exists, what a change affects, and whether it is safe to ship.
I work across product, interface, data, and infrastructure. The throughline is simple: turn difficult systems into software people can understand and use.
The best AI products understand relationships: the people, decisions, tools, and evidence around the task.
Useful autonomy needs clear milestones, durable state, and outputs a human can verify, not a mysterious spinner.
Systems should move fast on preparation while keeping consequential actions behind explicit human control.
Why weekly Grok Bot limits run out in 1 to 3 days, what X users are reporting, and 8 fixes that stretch the same plan.
Free Grok Bot templates for everyday jobs, from a morning AI briefing to meeting notes. Each one drafts, you approve, and only then does anything leave your hands.
Snowflake just shipped privilege ceilings for agent sessions. Here is the same pattern as a tiny TypeScript check: agent access is user access intersected with a task ceiling.
