⚬ Enhanced caching resilience with feature toggles for digital banking services backend to increase system reliability.⚬ Designed and implemented high-performance and OpenAPI-compliant APIs using asynchronous programming in Java Vert.x, serving 2000 debit transactions per hour.

⚬ Wireless Mobile Network Lab (Prof. Hung-Yu Wei)⚬ Conducted researches in resource allocation optimization using edge computing and game theory.⚬ First-authored conference paper "Collaborative Edge Caching with Multiple Virtual Reality Service Providers Using Coalition Games" accepted and presented in IEEE WCNC 2023.⚬ First-authored journal paper “Multi-Service Edge Computing Management with Multi-Stage Coalition Game Task Offloading” published in IEEE TNSM Volume: 21, Issue: 3, June 2024.

⚬ Involved in the full software development lifecycle, including design, development, testing, and monitoring in production.⚬ Architected and implemented a scalable microservices architecture for serving 150 million users globally.⚬ Created CI pipelines building Docker images and measuring code quality with SonarQube, automated deployment to Kubernetes clusters with ArgoCD, and monitored with Grafana and Prometheus.⚬ Developed REST and gRPC APIs in Go with 90% test coverage, and enhanced code modularity and reusability with dependency injection and the service / repository pattern.⚬ Designed and implemented a high-performance data retrieval and storage system, utilizing cronjobs for automation and multithreading for efficient transfer of 27M records from Amazon S3 to Redis in under 10 minutes.

⚬ Trained an ML model to predict if an incident needs manual review or intervention.⚬ Created a CI pipeline to periodically fetch incident data from ServiceNow, classify incidents using the trained ML model, and update to Google Sheets, reducing manual monitoring time by 30 minutes per day.⚬ Presented to the US team and is used in production.

⚬ Built a unified platform integrating multiple ordering methods, payment systems, delivery services, and invoice systems, serving over 200 restaurant owners and 10k customers.⚬ Developed full-stack features using jQuery and Laravel, with MySQL and MongoDB for storage.⚬ Created a CI/CD pipeline to containerize the application and push the Docker image to Google Kubernetes Engine automatically.
