with 15+ years of fintech CTO experience building credit decisioning engines and lending systems from scratch, I founded TheScoreGuide to bridge the gap between how underwriting algorithms actually work and what consumers are told. My production experience spans automated underwriting systems to AI-powered lending platforms — the same technical knowledge that powers the systems determining your loan approval and interest rate.
