About
I build and run the systems a business actually depends on — ERP, inventory, accounting and electronic invoicing across four companies in three countries. My work sits where correctness of financial data and continuity of service are not features but the whole job.
Most recently I led a full ERP platform migration (Odoo 14 → 19) end to end, with no data loss, and built an automated monitoring system that reconciles inventory against the general ledger and surfaces failures before users notice them. I work mainly in Python, SQL and PostgreSQL, with regulated electronic invoicing for the tax authorities of Chile, Colombia and Peru.
Writing
Migrating five major versions forward across four companies and three countries — and why the failures that raised no error were the expensive ones.
Building a health check that reconciles inventory against the general ledger, what it found that no report showed, and the detector of mine that was confidently wrong.
