I work on the CRM layer that sales and operations teams end up relying on once customer updates, follow-up, ownership, and team handoff all need to hold together inside one working system.
Over the last 10+ years, a lot of my work has lived in that space. Lead routing, ownership rules, pipeline behavior, follow-up logic, customer status, and the integration work around it. The aim is to keep CRM, internal tools, and the systems around them moving from the same set of signals instead of pushing people back into spreadsheets, inboxes, and manual checks.
Much of that experience comes from healthcare, fintech, and other operations-heavy environments where timing, record accuracy, and follow-through show up quickly in daily work. HubSpot, Salesforce, and custom CRM environments have all been part of that work, along with workflow automation, API integrations, and the backend work needed to keep those systems reliable once teams start depending on them.

When your operations are running blind, every day costs you money.
I help manufacturing and operations companies build the data systems that give leadership real visibility โ so problems get caught early, decisions get made faster, and KPIs actually drive behavior.
What makes me different: I've sat in your chair.
As a Shift Manager I led 100+ person teams. As a Process Improvement Manager I reduced production stoppages by 85%. As a Project Manager I delivered $1M+ in savings. I know which questions to ask because I've lived the problems you're trying to solve.
As a dropshipping E-commerce operations manager I built multi-channel sales reporting from scratch โ ingesting Amazon Seller Central data, allocating courier and channel info, and calculating profits and operational kpis. Improved profit in 32%, refunds recovery in 41+% and reduced order defect rate by 37% with data/process improvements.
What I build:
โข Power BI dashboards that support real decisions (not just display data)
โข KPI frameworks that align teams to measurable results
โข Real-time operations monitoring systems
โข Process improvement roadmaps with clear ROI
My stack:
Power BI ยท SQL ยท M ยท DAX ยท PowerQuery ยท RLS ยท dbt ยท Python
API integration ยท GitHub ยท M365 ยท ERP ยท Syspro ยท Excel ยท Google Sheets
Credentials:
ยท Power BI Associate
ยท WCM International Auditor
ยท Lean Office Consultant
ยท Master's in Automotive Engineering (Politecnico di Torino)
ยท Mechatronics Engineer
Most consultants ask "what dashboard do you want?" โ I ask "what problem are you trying to solve?" Then I diagnose root causes, develop the right KPIs, and build systems your team will actually use.
