Cloud-native mortgage platform serving millions of B2B and B2C users

Business Context

Consumer mortgage platforms require 24/7 availability, strict regulatory compliance, and seamless integrations across identity, payments, and servicing vendors.

Overview

At Sagent, I architect and develop cloud-native microservices for a 24/7 consumer mortgage platform. Key initiatives include modernizing authentication from single-IDP to a secure multi-IDP OIDC proxy architecture, building payment processor integrations, and optimizing observability systems.

This work spans the full integration lifecycle — from vendor discovery and architecture design through go-live and production support — across identity providers, payment processors, and servicing platforms.

Key Contributions

  • Modernized authentication to secure multi-IDP OIDC proxy architecture
  • Scaled client onboarding to 4–5 concurrent launches via automation
  • Reduced telemetry costs by 50% through optimized observability strategy
  • Established Sev 1 incident response standards and SLA frameworks
