SKILLS
ABOUT MARIO ZELAYA GUERRERO
With 16+ years in data analysis and business intelligence, I transform complex credit, financial, and operational data into actionable insights that drive better decisions and real results—currently at Equifax, where I work daily with bureau data to support lending and risk strategies.I\'ve built predictive models and custom scorecards (including regional solutions for Central America in banking, retail, telecom, and auto), modernized legacy Spotfire dashboards with ECharts and multi-tenant architectures, migrated from BigQuery Information Links to SBDF to cut cloud costs, and added AI features like Vertex-powered chatbots and generative summaries. These efforts have reduced defaults, increased approvals, doubled user adoption, and created competitive advantages without heavy bureaucracy.Key achievements: Led regional teams to launch self-service Spotfire platforms and Market Credit Trends apps (El Salvador/Honduras), delivering real-time credit trends, forecasting, and market insights for proactive bank/retail strategies. Engineered Ignite Marketplace contract work: scalable multi-tenant dashboards with config files/SBDF, routine maintenance, and cost-saving migrations—ensuring reliable, personalized analytics. At Radian, automated SAS/Tableau reporting pipelines with crontabs—eliminating manual Excel work and accelerating mortgage risk/underwriting insights. Co-founded Smart Insight Solutions (El Salvador), developing affordable BI platforms and SaaS tools (The People App for HR, EZBilling invoicing, SIS Cloud storage, SIS Mail) to help businesses optimize operations without expensive licensing.I solve common pain points: outdated reporting, inefficient bureau data, compliance issues, high cloud costs, and legacy systems. I offer scorecard redevelopment, dashboard modernization, automation, and tailored BI consulting with fresh Equifax-level expertise and practical, cost-effective delivery.Based in Cumming, GA (Atlanta area) with roots in El Salvador—selectively available for remote/project-based work worldwide. If you\'re a lender, fintech, bank, retailer, or organization tired of generic tools or high-cost vendors, message me. Let\'s chat about your challenges—no pitch, just real conversation.
