About

Accurate, documented, and easy to read.

By day I work full-time as a data analyst, turning messy data into clear visuals and making reports accurate, documented, and easy for busy people to read. I bring that same care to contractors, home-service companies, and other local businesses that are tired of piecing their numbers together by hand at the end of every month.

No jargon, no lock-in, no mystery software. If you can open a spreadsheet or a web browser, you can use what I build.

Services

What I can help with

Built for roofers, HVAC and plumbing shops, remodelers, landscapers, cleaning companies, and other Lincoln small businesses.

🧹

Data Cleanup

Duplicates, mixed-up dates, five spellings of the same vendor. I clean and combine your exports into one master sheet you can trust.

📊

KPI Dashboards

One page that shows what matters: revenue and margin by job, quote-to-close rate, overdue invoices, monthly trends. Built in Excel or Google Sheets.

🌐

HTML Dashboards and Simple Web Pages

Lightweight dashboards and single-page sites that open in any web browser. There's nothing to install and nothing to log into. Open the file and it works.

✨

Website Refreshes

A visual and practical refresh for small-business sites: clearer layout, better mobile view, faster pages, and an easy way for customers to reach you.

📅

Monthly Reporting

I refresh your numbers each month and send a one-page "what changed and why" summary.

Report Tune-ups

Already have a dashboard or report? I'll check the math, tighten up the layout, and make it easier to read and keep up to date.

How I Work

From messy file to something you'll use

  1. Free first look

    Send a sample spreadsheet (sensitive info removed) or your website link. I'll tell you what I'd fix first.

  2. Fixed quote

    You know the price and timeline before I start.

  3. Short kickoff call

    15 to 30 minutes so I understand what you need to see.

  4. First draft fast

    Usually within a few business days of kickoff.

  5. Walkthrough and handoff

    A short video and a call so you can use it and maintain it yourself. Everything is documented, and nothing is locked down.

Contact

Got a spreadsheet nobody trusts?

Send it my way (with sensitive info removed) and I'll send back three quick fixes, free and with no strings attached. If it makes sense to keep going, we can talk about packages. If not, the fixes are yours to keep.

I'm available evenings (Central time) and weekends, and I reply within 24 hours on weekdays.
