Senior Backend Engineer

About

Senior Backend Engineer with 7+ years owning high-throughput, event-driven systems at American Express and JPMorgan Chase. I design and deliver low-latency APIs and real-time data pipelines handling hundreds of thousands of transactions daily across credit risk decisioning, card originations, and compliance-critical domains. Deep expertise in Java, Kafka, and distributed microservices; track record of driving cross-team technical decisions, mentoring engineers, and shipping observable, resilient systems at scale.

Experience

American Express
  • 150k+ credit decisions/day: Designed and owned end-to-end event-driven data pipelines in Java / Spring Boot / Kafka, maintaining sub-1-second latency SLAs at sustained production load.
  • Drove the design and delivery of gRPC and REST microservices for real-time credit limit assessments; defined service contracts and integration patterns adopted across downstream platform teams.
  • Engineered asynchronous, multi-threaded compute workflows to derive risk variables from raw transactional data, enriching and publishing to analytics platforms powering credit risk models.
  • Led alignment with product managers and data stewards to define critical risk variable schemas, ensuring accuracy and compliance across ingestion, transformation, and delivery layers.
  • Owned end-to-end encryption and PII protection for sensitive risk variables, meeting enterprise security and regulatory requirements with zero compliance findings.
  • Mentored junior engineers and new hires through code reviews, pair programming, and 1:1s; accelerated onboarding and raised team code quality standards.
JPMorgan Chase & Co.
  • Built and scaled Java Spring Boot microservices processing 20k+ card applications daily, integrating with real-time decisioning systems for automated approvals across co-branded products.
  • Designed and delivered REST APIs for multiple co-branded card products; owned end-to-end integration from API contract through production deployment in collaboration with partner engineering teams.
  • Implemented multi-layer encryption protocols at partner integration boundaries, satisfying financial regulatory compliance standards across all product lines.
  • Built Splunk dashboards and proactive alerting that reduced mean time to incident detection; became the team's primary observability reference during on-call rotations.
Fannie Mae
  • Developed backend APIs for a securities trading platform processing $1B+ daily, enabling reliable integrations with external customer systems under high-volume trading conditions.
  • Reduced manual regression testing time by 70% by building Jenkins-integrated shakeout scripts run automatically off-hours, eliminating a recurring pre-release bottleneck.
