Boise, ID · building in public

Cole Hollander

I build AI systems, and I learn fast enough that the list keeps growing.

Sophomore studying Information Technology Management at Boise State. I go all the way in on things and usually end up shipping something. Right now that something is Jarvis.

Right
now

  1. Building

    Jarvis

    A personal AI agent that lives in iMessage. I text it to hand off work, and it texts me first when my calendar, email, or reminders need attention. It remembers context across the thread.

  2. Learning

    How to orchestrate agents

    Getting subagents and automations to handle research, scheduling, and drafts without me babysitting each step. Background work that comes back done.

  3. Shipping

    In public, weekly

    Build notes and what broke. A first real post hit 30k impressions, so now I am trying to understand why, not just repeat it.

What I'm
learning

I treat skills like commits. Here's the recent history, newest first, and what each one unlocked.

  1. Proactive agents

    still learning

    Jarvis now messages me first, watching calendar, email, and reminders, instead of waiting to be asked. Triggers, not prompts.

  2. MCP servers

    shipped

    Built a Canvas MCP server that gives Claude direct access to my assignments and due dates. Other BSU students picked it up.

  3. Vault-as-memory

    still learning

    Structured an Obsidian second brain so the model already knows what I am working on. Context beats prompting.

  4. Astro + islands

    shipped

    Rebuilt this site to ship near-zero JS by default and hydrate only the parts that move. The page you are reading.

  5. SwiftUI + SwiftData

    parked

    Built Finn, a local-only subscription and trial tracker, end to end on iOS. Now winding down, but it taught me the platform.

  6. Eval-driven iteration

    still learning

    Stopped guessing whether a prompt change helped. Started measuring it.

Things I've shipped, and the one I'm chasing.

Personal AI · flagship

Jarvis

A personal AI agent I reach the same way I reach anyone: over iMessage. I text it to delegate work, and it messages me first when something needs me, calendar conflicts, an email worth a reply, a reminder coming due. Persistent memory across the thread, real actions, no app to open.
