About 5AlarmData

The data is there.
Writing about it isn't.

5AlarmData exists because I've seen what fire departments actually do with their incident data and what they don't have time to do. This tool is built to close that gap.

Where this came from

For two years, I worked as a data scientist and engineer at a company that built analytics platforms specifically for fire departments. Every day, my job was turning raw incident records (NFIRS exports, RMS data, dispatch logs) into insights that department leaders could actually use.

I built dashboards. I wrote queries. I modeled response time trends, staffing patterns, call type distributions. And in every conversation with fire chiefs, I kept hearing the same thing: "We have the data. We just don't have time to do anything with it."

Chiefs were spending evenings and weekends writing board reports by hand, pulling numbers from their RMS, copying them into Word, trying to make it readable for a room full of city council members who didn't know what a NERIS module was. Grant narratives sat half-finished because nobody had time to write the narrative around the numbers. ISO prep happened once a year in a panic.

The data was already there. The problem wasn't the data but it was the writing.

What two years inside fire data taught me

Most fire departments are data-rich and insight-poor. They've been collecting incident data for years (some for decades). The people responsible for acting on that data are the same people responding to calls, managing personnel, and presenting to boards. There's no data analyst on staff. There's rarely even a dedicated admin for this.

I also learned that fire chiefs are not the problem. They understand their departments deeply. They know the trends. They can tell you exactly why response times are up in the south district or why EMS calls have spiked in the last quarter. What they can't do is spend four hours translating that knowledge into a formatted board report every single month.

5AlarmData is the tool I wished existed when I was sitting across the table from those chiefs. Upload the file you already export. Tell me what you need. Get a finished document back in minutes.

Background

Founder
5AlarmData
Building the tool that turns fire department incident data into finished board reports, grant narratives, ISO evidence packs, and compliance checks — automatically. Designed specifically for chiefs who don't have a data team.
2 Years
Data Scientist & Engineer
Fire Department Analytics Platform
Worked directly with fire departments across the country, building analytics tools and deriving operational insights from NFIRS and NERIS incident data. Specialized in response time analysis, staffing patterns, call volume trends, and compliance reporting. Saw firsthand the gap between the data departments had and what they were able to do with it.

Education & Early Career
Built a foundation in data engineering, machine learning, and applied analytics. Developed expertise in working with structured operational datasets — the kind fire departments generate every day but rarely have the resources to fully analyze.

Why this matters to me

Fire departments serve their communities with limited resources, limited staff, and limited time. The administrative burden on chiefs, especially in small and mid-size departments, is significant. Reporting requirements are growing. NERIS compliance is mandatory. Grant competition is fierce. ISO reviews happen on a cycle.

Every hour a chief spends writing a board report is an hour not spent on training, operations, or community risk reduction. 5AlarmData is about giving that time back.

The data already tells the story. I'm just making it easier to share it.
