About

Senior Software Engineer and Lead Architect with 18+ years of experience modernizing large-scale enterprise platforms across auto-finance, healthcare, and media domains. I specialize in transforming legacy monolithic systems into cloud-ready, event-driven microservices using Java, Spring Boot, Kafka, AWS, Kubernetes, and modern DevOps practices. At Credit Acceptance, I lead modernization initiatives that decompose legacy platforms into resilient, domain-oriented microservices following industry-standard architectural patterns such as Ingestion, Validation, Enrichment, Orchestration, and Egress. My work focuses on scalability, fault tolerance, idempotency, and safe production rollout strategies using Blue-Green and Canary deployments, feature toggles, and GitOps workflows with ArgoCD. I bring deep expertise in enterprise decisioning and rules-based systems, designing and migrating complex business logic using FICO Blaze Advisor and FICO Analytical Cloud. This includes on-prem to cloud rule migrations, Decision Modeler artifacts (BOM, BOS), PLOR orchestration, and Hotlists to support dynamic, auditable, and explainable decision workflows integrated with modern microservices. This background provides a strong foundation for governed and transparent AI-augmented decision platforms. My architectural experience increasingly intersects with AI and GenAI-ready platforms, where I focus on designing systems that can safely incorporate machine-assisted intelligence. I have worked extensively with rule-driven and data-driven pipelines that form the backbone of applied AI systems, and I am actively building expertise in GenAI architecture patterns such as Retrieval-Augmented Generation (RAG), prompt orchestration, AI service isolation, and observability in regulated environments. I approach AI integration from an enterprise architecture lens, emphasizing governance, explainability, data integrity, and operational safety rather than experimental models alone. In addition to architecture and development, I bring extensive production support and on-call experience for mission-critical systems with strict SLAs. I actively use Splunk, Dynatrace, CloudWatch, and distributed tracing to diagnose production issues, perform root-cause analysis, and drive long-term platform improvements rather than short-term fixes. Previously, as a Senior Solution Architect at Florida Blue, I led the architecture and delivery of a Group Delinquency platform, combining Spring-based microservices, FICO Blaze rules, enterprise data pipelines.

Detroit, Michigan, United States

Leading enterprise-scale legacy modernization, transforming monolithic systems into domain-aligned Spring Boot microservices. Designed and implemented end-to-end processing pipelines using standardized architectural patterns. Created Springboot Rest Webservices for: - Ingestion of external vendor data via REST, Kafka, and batch interfaces - Sanitization & Validation using schema checks, rule engines, and feature toggles - Enrichment with reference data, pricing logic, and decision outputs - Orchestration of multi-step workflows with retries, idempotency, and correlation tracking - Egress via synchronous APIs and asynchronous Kafka events to external partners Developed and maintained FICO Blaze Advisor business rules and actively supported migration from on-prem Blaze Advisor to FICO Analytical Cloud including Decision Modeler, BOM, BOS, Ruleflows, PLOR and Hotlists. Built event-driven architectures using Kafka to decouple services, improve resiliency, and scale horizontally.Implemented Feign clients for clean, contract-driven service-to-service communication. Designed and supported Blue-Green and Canary deployment strategies enabling controlled rollouts. Leveraged ArgoCD (GitOps) for deployments and environment parity. Integrated feature toggles to decouple deployment from release and enable rapid rollback. Implemented centralized observability using CloudWatch, Dynatrace, Splunk, improving incident detection and RCA Designed AI-ready decisioning architecture by combining deterministic rule engines (FICO Blaze, Drools) with data-driven pipelines, enabling future augmentation with GenAI components while preserving explainability, auditability, and regulatory compliance. Defined architectural patterns for safe GenAI integration, including AI service isolation, input/output validation, prompt orchestration boundaries, and observability hooks. Used Python for automation, data validation and operational tooling to support ingestion / testing workflows.
