Exequiel Santander

Systems Engineer on a mission to simplify your financial life. I’ve seen too many founders and freelancers lose sleep over messy spreadsheets and expensive subscriptions that don't deliver. That’s why I build "Financial Engines"—automated Google Sheets designed to give you your time and peace of mind back. I don’t just sell templates; I build the clarity you need to grow your business without the overhead. Let’s stop the guesswork and start building your legacy with precision.
