The platform ingests, classifies, and extracts structured data from mortgage documents (W-2, 1003, appraisals, title) using OCR and NLP pipelines, then validates extracted fields against federal compliance rules (TRID, RESPA, HMDA), underwriting policies (DTI, LTV, credit score), and configurable per-tenant business overlays. Validation results are persisted to tenant-scoped data stores and delivered to Loan Origination Systems via REST APIs and webhooks. The architecture features confidence-scored AI extraction with a human review fallback, an immutable audit trail for regulatory examination, and a policy-driven rules engine that enables onboarding new lenders through configuration rather than code deployment. Responsibilities: Served as Java Tech Lead and principal architect - drove end-to-end solution design from requirements gathering through production deployment, working directly with client stakeholders to translate regulatory and business requirements into scalable system architecture. Led a cross-functional engineering team through full SDLC in an Agile environment, running sprint planning, architecture reviews, and technical mentorship to ensure on-time delivery of high-quality features. Defined and enforced engineering standards across the team, including API contracts, code review practices, and CI/CD pipeline governance via GitHub Actions workflows. Designed a microservices architecture on AWS, deploying containerized Spring Boot services to ECS clusters via ECR with infrastructure provisioned entirely through Terraform for repeatability and auditability. Architected multi-region AWS infrastructure covering ECS, Aurora PostgreSQL (relational data model with complex entity relationships), MongoDB (audit log storage), API Gateway, S3 (static content hosting), and CloudFront (CDN distribution). Centralized secrets management using AWS Secrets Manager, eliminating hardcoded credentials and enabling secure runtime configuration injection across all services. Exposed internal microservices to external consumers through API Gateway proxy configurations, enabling secure and rate-limited access for LOS integrations. Built a suite of RESTful microservices in Spring Boot implementing the Rules Engine core - document ingestion, field validation, compliance checking, and tenant-scoped result delivery. Implemented token-based authentication and authorization using Spring Security and JWT, securing all API endpoints with role-based access control. Designed and optimized the Aurora PostgreSQL data model supporting multi-tenant isolation, complex relational structures, and audit requirements; leveraged Spring Data JPA for data access layer abstraction. Integrated AWS Bedrock foundation model APIs (Claude, Titan) to drive intelligent document classification and field extraction across mortgage document types (W-2, 1003, appraisals, title reports), replacing brittle rule-based parsing with confidence-scored AI predictions. Designed a human-in-the-loop fallback architecture - extraction results below configurable confidence thresholds are automatically routed to a review queue, ensuring accuracy guarantees while minimizing manual intervention on high-confidence documents. Built the AI Rules Engine layer that chains Bedrock extraction output into the downstream compliance and underwriting validation pipeline, enabling end-to-end straight-through processing for clean documents. Designed and delivered React/Redux web interfaces for human-review workflows and lender onboarding configuration, collaborating with business stakeholders through iterative UI reviews. Accelerated delivery velocity by integrating AI coding tools (Claude Code, GitHub Copilot) into team workflows for boilerplate generation, code review support, and test scaffolding. Authored Terraform modules for repeatable AWS infrastructure provisioning; integrated Kafka for event streaming and Drools for the policy rules engine.
