Built and iterated R&D prototypes for a cloud-based simulation platform, integrating Kafka data pipelines, Java Spring services, WebSocket messaging, and Vue/Cesium visualization.

Refactored frontend and Spring backend modules in a 50,000+ line codebase, reducing complexity and improving application performance.

Designed RESTful APIs with Spring Boot and integrated them with Vue/React frontend components and external services.

Led a monolith-to-microservices migration by defining service boundaries and extracting services while maintaining feature parity.

Built and deployed features in a Dockerized microservices architecture, improving modularity and scalability across multiple services.

Remediated security vulnerabilities by upgrading application dependencies and resolving CVE findings while maintaining build stability and compatibility.

Migrated the persistence layer to Spring Data JPA/Hibernate, reducing query complexity, improving endpoint latency by 200%, and cutting database load through batching and caching.

Supported four live customer-facing product demonstrations by troubleshooting real-time technical issues and translating platform capabilities into clear technical value.

Built distributed data pipelines and real-time streaming services for a cloud-based Monte Carlo simulation platform, scaling concurrent entity support from about 100 to about 2,000.

Improved scalability of a Java Spring Kafka/WebSocket backend for a Vue.js/Cesium real-time mapping application, reducing CPU utilization from about 100% to about 25%.
