Tired of broken processes and spreadsheets nobody actually uses?

I help businesses fix both sides of the problem: building clean data systems and the process documentation to make them actually stick. What I help with: — SOPs and workflow documentation — Process mapping and bottleneck analysis — Excel & Access dashboards, trackers, and databases — SWOT analysis and operational recommendations — Cross-functional coordination and client-facing reporting Whether you need a quick-turnaround dashboard or a full workflow overhaul, I work fast, communicate clearly, and deliver things that get used. I'm based in Maine but work across time zones — US, Australia, Europe, no problem. Clients describe me as a "clear communicator, committed to quality, and reliable" — and that's exactly how I work on every project. If that's what you need — let's talk.

I help small business owners get organized: clear systems for how work gets done, and clear numbers showing how the business is doing. What I do: – 𝐁𝐮𝐬𝐢𝐧𝐞𝐬𝐬 𝐬𝐲𝐬𝐭𝐞𝐦𝐬: company hubs, trackers, and workflows in Notion, Dubsado, Honeybook, and Airtable, built so your team actually uses them – 𝐒𝐎𝐏𝐬 & 𝐩𝐫𝐨𝐜𝐞𝐬𝐬 𝐝𝐨𝐜𝐮𝐦𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧: get your processes out of people's heads into step-by-step docs anyone can follow – 𝐅𝐢𝐧𝐚𝐧𝐜𝐢𝐚𝐥 𝐝𝐚𝐬𝐡𝐛𝐨𝐚𝐫𝐝𝐬: clean Google Sheets dashboards showing revenue, costs, and profit, designed for owners, not analysts – 𝐃𝐚𝐭𝐚 𝐜𝐥𝐞𝐚𝐧𝐮𝐩 & 𝐫𝐞𝐩𝐨𝐫𝐭𝐢𝐧𝐠: messy spreadsheets and exports turned into organized, recurring reports – 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐨𝐧: connect your tools (Zapier, Airtable, Mailchimp) so information moves without manual work A recent example: A business owner came to me juggling his numbers across scattered spreadsheets and gut feel. I built him a Google Sheets dashboard with automated calculations and plain-language recommendations built into the sheet itself, not just charts to interpret. Years later, it's still what he runs his cleaning company on, and he uses it live on calls with his own consulting clients. His words on that build are in the testimonials below. How I work: I ask the right questions before building anything. I'd rather flag a problem in your data than quietly guess at what you meant. And I build systems you can run and adapt yourself after I'm gone — if it falls apart without me, I didn't do my job. About me: I've spent 12 years in data, analytics, and process improvement roles, building tracking systems, documenting processes, and turning messy data into reports busy decision-makers act on. I led one agency office's full analytics modernization, including building its first dashboards and training staff. My portfolio includes real builds still in daily use years later. I work in English (native) and Spanish (advanced). If your business feels disorganized, or you're making decisions without the full picture, send me a message and tell me what you're trying to fix. Happy to take a look and tell you honestly whether I can help.
