Distributed systems
Designing event-driven services, resilient contracts, replay-safe consumers, and observable failure boundaries.
Cloud platforms
Shipping containerized workloads across AWS, Azure, and GCP with Kubernetes and infrastructure as code.
Security by design
Applying OAuth, OIDC, JWT, MFA, RBAC, audit trails, and compliance-aware delivery from the platform edge.
Data at scale
Tuning relational and distributed data stores for high-throughput transactions, healthcare records, and telemetry.
EXPERIENCE
Leading cloud-native modernization of core banking services across Java, Angular, AWS, and Kubernetes.
- Architected Spring Boot APIs and event-driven AWS services for core banking workflows.
- Improved PostgreSQL query performance by 35% and reduced downtime by 40% through proactive observability.
- Mentored engineers and led SAFe planning, demos, architecture documentation, and delivery alignment.
Built secure FHIR-based services and React care workflows across a multi-tenant health-data platform.
- Reduced API latency by 25% and optimized 5TB+ of longitudinal clinical and claims data.
- Implemented OAuth2/OIDC security and healthcare interoperability through FHIR R4 endpoints.
- Improved deployment consistency with Docker, Kubernetes, Jenkins, Terraform, and CloudFormation.
Combined high-fidelity 3D CAD experiences with streaming fleet telemetry and cloud-scale storage.
- Delivered React, TypeScript, WebGL, and Three.js interfaces for CAD rendering and annotation.
- Designed Spring Boot and Node.js services across Kafka, Cassandra, MongoDB, MySQL, and Redis.
- Led a RabbitMQ-to-Kafka migration for high-throughput telemetry and exactly-once processing.
Engineered a mission-critical fraud platform for live card and ACH risk decisions on Azure.
- Built React dashboards with WebSockets and Server-Sent Events for live fraud operations.
- Orchestrated exactly-once Kafka pipelines and high-throughput Cassandra transaction models.
- Reduced operating cost by 40% and improved scalability by 60% with Azure serverless services.
Developed clinician-facing applications and real-time patient alert services on Google Cloud.
- Created React workflows and Spring Boot APIs for patient data retrieval and clinical alerts.
- Deployed Dockerized services to GKE with Helm and Terraform.
- Processed real-time vitals with Kafka Streams and protected PHI through RBAC and ABAC.
