Iván E. Villanueva Sandoval (Svei)

Public Accountant (Mexico) & Software Development Engineer · Founder, Excel Solutions V

Zapopan, Jalisco, Mexico

Public Accountant (Mexico) and Software Development Engineer, with a law degree as well. I work where Mexican tax accounting meets software engineering: I build CFDI/SAT automation tools, audit-simulation workbooks, and Python pipelines that turn tax data into clean, importable records, and I create Spanish-language content that teaches the same skills.

I earned my Public Accountant degree from the University of Guadalajara (2003), started at Deloitte México, then spent nine years (2005–2014) at Mexico's tax authority, the SAT. There I built a case- and deadline-tracking system, maintained the tax-filing and payments system, and, in Vigilancia Profunda within the Taxpayer Services Administration, developed workbooks that served as a pre-audit compliance screening program. I was later promoted to Department Head in that same administration. In 2023 I earned my Software Development Engineering degree from Mexico's Open and Distance University (UnADM).
