Owned backend/service upgrades and operational hygiene (Fastify/Node.js), improving security compliance and service reliability for a high-traffic production environment.

Designed and drove observability initiatives (performance metrics plan + dashboards), enabling data-driven prioritization and sustained performance improvements.

Built internal platform tooling (e.g., IntelliJ plugin, navigation/rendering utilities) to accelerate development and reduce onboarding friction.

Led cross-team reliability work by diagnosing complex contract/serialization/state issues and driving durable, regression-resistant fixes.

Maintained strong Web performance fundamentals (Core Web Vitals, bundle budgets, CI enforcement) as a supporting strength for platform work.

Addressed the sluggishness in dependency calculation by prioritizing job sequence and separated the system using a message queue, enhancing both availability and handling high QPS efficiently.

Designed an on-prem and AWS hybrid workflow solution that integrated AWS ARM-based machines, enabling the efficient deployment of development environments with structured schema data.

Created a job management server hosting RESTful APIs by Rails, which chips designers can submit EDA jobs into AWS and keep tracking of them.

Replaced the load sharing queue and distributed executors from local cluster servers with AWS SQS to provide a highly available system.

Introduced Docker-based services running by AWS Batch, ECS, ECR to build a flexible and easy-deploy pipeline for future development.

Advanced the testing pipelines by Jenkins and docker container, fully integrated with the Github action. (reduce 10% bugs)

Enhanced and unified the API documentation for a faster-developing cycle and by Swagger, Swagger-UI, and API Blueprint.

Developed a project that deployed web services with Docker containers and helped the company receive a client's offer (TSMC).

Introduced cloud microservices (AWS Lambda) and integrated with daily report generator (Reduce 50% of memory used and 10% cost).
