I help you see your money clearly — so you can make better decisions with it.
That means showing you the actual numbers behind your financial life: what a transfer really costs, what an account really earns, what an investment is really doing, what the official inflation figure leaves off the receipt. Across every layer — where money sits, how it moves, what it buys, where it grows. Once the picture is clear, the decisions get easier.
This is especially for people living between two financial systems, supporting family across borders, or learning a system they weren't raised inside. But the math applies to anyone who wants a sharper view of their own money.
In every issue of this newsletter, one thing — a fee, a habit, a currency, an inflation figure, an account type, a transaction pattern — broken down with the actual data. You walk away with a clearer view of what's happening and a better foundation for what to do with it.
Why it matters: knowledge is what gives people power over their own financial life. When you can do the math on your own money, the decisions become yours instead of someone else's. That builds stronger families. Stronger communities. The kind of freedom that comes from actually understanding what's happening to you.
I do this because numbers have already done it for me. Years architecting, building, and analyzing data systems — through the energy sector at DTE, automotive at Marquardt, then at Comerica Bank, where I worked on ACH and SWIFT transfer data and the Money Transfer System itself — the plumbing that actually moves money securely between US banks and across borders. That's where I learned how much a clear set of numbers can tell you about what's really happening with money.
I've used that same clarity on my own life — bookkeeping for my real estate investments, working through my own taxes, dialing in habits one at a time. None of it required a special background. Just the willingness to look at the data and decide the next move from there. If it can work for me, it can work for anyone willing to do the math.
In English and Spanish. No politics. No get-rich promises. Just the math, explained clearly.
I love numbers. I love statistics. I love uncovering the stories hidden in them — and that's what lands in your inbox.
