Work History
Software Engineer
PNC Bank
Arlington, Texas
01.2023 - Current
- Re-architected enterprise loan processing and underwriting workflows into domain-aligned Spring Boot services, supporting application intake, validation, underwriting tasks, credit decisioning, and funding in a regulated banking environment.
- Designed workflow orchestration and state machine patterns to standardize case progression, improving SLA adherence and reducing manual rework by [X%].
- Implemented secure REST APIs for application intake, document checklist/status, underwriting task queues, and decision capture with OpenAPI specs and versioning strategies.
- Persisted core loan entities in PostgreSQL (relational) and stored application events/audit history in DynamoDB (NoSQL) (or similar) for scalable append-only access and fast retrieval.
- Implemented resilient downstream integrations (credit/identity, core banking) using timeouts, retries, circuit breakers, and idempotent updates to improve reliability under dependency instability.
- Built asynchronous processing with RabbitMQ/SQS for task distribution and DLQ handling; improved throughput, and isolated failures for high-volume processing days.
- Improved performance with Redis caching, query/index tuning, and batch processing; reduced processing latency by [X%] during peak periods.
- Implemented test automation: JUnit 5/Mockito unit tests, Spring integration tests, and Playwright/Cypress e2e suites; enforced CI quality gates and reduced regressions by [X%].
- Built and maintained CI/CD pipelines (build/test/scan/deploy) with safe deployments (feature flags, blue-green/canary), and rollback procedures to increase release confidence.
- Operationalized services with observability (APM + logs + metrics + tracing), defined SLIs/SLOs for critical workflows, and improved on-call response with runbooks and alert tuning.
- Participated in incident response and postmortems; drove preventive fixes that reduced recurring production issues and improved MTTR by [X%].
- Collaborated via pair programming, code reviews, and mentoring; documented ADRs and operational playbooks to improve maintainability and onboarding.
Software Engineer
Johnson & Johnson
Dallas, Texas
09.2019 - 12.2022
- Engineered and enhanced a supply chain quality and serialization platform using Java 17 and Spring Boot, enabling end-to-end traceability of product serials and lots across manufacturing, packaging, and distribution operations.
- Collaborated with quality, manufacturing, and business stakeholders in an Agile/Scrum environment to translate regulatory, operational, and compliance requirements into well-defined user stories and delivery milestones.
- Designed domain-driven microservices and REST APIs to capture serialization events, aggregation relationships, shipment verification, and exception workflows, ensuring data accuracy and compliance-ready audit trails.
- Implemented a polyglot persistence strategy, storing authoritative transactional data in Oracle (relational) while leveraging Cassandra (wide-column NoSQL) for high-volume, append-heavy event history and rapid lookups.
- Built search and operational visibility capabilities using Elasticsearch/OpenSearch, enabling fast trace queries, product lineage analysis, and efficient exception investigation by quality teams.
- Secured services using OAuth2/OIDC, role-based access control (RBAC), and service-to-service authentication, enforcing encryption in transit and at rest to meet regulated industry security standards.
- Developed event-driven processing pipelines using Apache Kafka, handling high-throughput bursts from plant and warehouse systems while ensuring consistency through idempotency, retries, DLQ handling, and event replay mechanisms.
- Strengthened platform quality through automated testing practices, including JUnit and Mockito unit tests, Spring integration tests, and consumer-driven contract testing (Pact), reducing cross-service integration defects by [X%].
- Built and maintained CI/CD pipelines with containerized builds and deployments, supporting canary and blue-green release strategies, automated rollbacks, and environment parity across development stages.
- Deployed and operated services in Dockerized Kubernetes environments, using Terraform for infrastructure consistency and repeatability across regulated environments.
- Implemented production observability with APM, centralized logging, metrics, and distributed tracing using Datadog/New Relic, ELK/Splunk, and OpenTelemetry to support proactive monitoring and rapid issue diagnosis.
- Defined and monitored SLIs and SLOs for event processing latency, throughput, and error rates; tuned alerts to reduce noise while ensuring rapid detection of quality-impacting issues.
- Participated in on-call rotations, leading incident triage and postmortems, and implementing preventive improvements that reduced recurring processing failures by [X%].
- Practiced pair programming for complex data model and event-processing changes, and mentored teammates on Spring Boot patterns, testing discipline, and production-readiness in regulated systems.

- Delivered end-to-end enhancements to a claims intake and adjuster workflow platform using Java 17 + Spring Boot, working in Scrum (refinement, planning, demos, retros) with Product and Claims Ops.
- Designed and implemented REST APIs for FNOL (First Notice of Loss), claim status, document upload, and adjuster task routing with OpenAPI contracts and backward-compatible versioning.
- Built workflow state transitions (triage → assignment → inspection → settlement) with validation rules and audit logging to improve traceability and reduce manual handoffs by [X%].
- Modeled core claim entities in PostgreSQL (relational) and stored flexible claim notes/attachments metadata in MongoDB (NoSQL); optimized indexing and query performance for high-volume searches.
- Implemented Spring Security (OAuth2/OIDC) with RBAC and least-privilege service-to-service access; added PII-safe logging and data masking to support privacy requirements.
- Integrated with downstream services (policy, billing, vendor/repair networks) via resilient REST calls and messaging; implemented retries, timeouts, and idempotency to reduce duplicate processing.
- Improved performance using Redis caching, pagination, and async processing for heavy operations; reduced key endpoint latency by [X%].
- Built test automation using JUnit 5/Mockito unit tests, Spring integration tests (Testcontainers where applicable), and Cypress e2e flows; increased coverage to [X%] and reduced escaped defects by [X%].
- Implemented CI/CD pipelines with automated build/test/security scans and environment promotions; supported safe releases using feature flags and rollback-friendly deployments.
- Established observability (structured logs, metrics, tracing), dashboards, and alerting; participated in on-call and drove postmortems to reduce recurring incidents and improve MTTR by [X%].
- Practiced pair programming on complex claim workflow refactors, led code reviews and documented ADRs/runbooks to improve maintainability and onboarding.
