SAHEL RAFAEL TAMAYO / OPERATIONS · TECHNOLOGY · ENTREPRENEURSHIP
Build better systems.
Make better decisions.
I’m a business executive and entrepreneur interested in how companies actually work—from sourcing and customer experience to smarter processes, responsible automation, and financial clarity.
Writing, research & perspective
Entrepreneurship
Operations, sourcing, business finance, customer experience, and the daily decisions behind execution.
Money
Cash flow, margins, credit, financial controls, and practical ways to weigh financial tradeoffs.
Real Estate
Property economics, rental reserves, investing decisions, and assessing real-estate risk.
HOW I WORK
Practical experience. Clearer execution.
The most useful business improvements are often invisible: clearer ownership, more reliable data, better purchasing decisions, and processes that hold up when things go wrong.
Operations & commerce
Making sourcing, fulfillment, service, and day-to-day workflows easier to understand, measure, and improve.
Systems & automation
Using software, AI, and well-designed processes to reduce repetitive work without losing accountability.
Economics & judgment
Looking beyond headline prices to costs, margins, cash flow, and the risks behind a decision.
