Two roles, one throughline: infrastructure people can trust.

Backend microservices and cloud-native infrastructure for client platforms, from API design through to the environment running it.

• Engineered scalable backend microservices and RESTful APIs aligned with 12-Factor App principles, keeping application design stateless for container autoscaling.
• Containerized multi-tier web applications using Docker multi-stage builds, reducing runtime image footprint and enforcing non-root security standards.
• Maintained automated CI/CD pipelines via GitHub Actions, incorporating automated unit tests, linting, and container registry publishing.
• Profiled runtime performance and tuned PostgreSQL connection pooling and query execution, mitigating latency spikes during peak traffic.
• Authored environment configuration standards, infrastructure runbooks, and deployment guidelines to bridge development and operations workflows.

Clean Architecture and configuration standardization work at HUST's software innovation center.

• Applied Clean Architecture principles to decouple core domain logic from framework dependencies and external database tiers.
• Standardized local development environments and configuration management across team setups, minimizing configuration drift between machines.
• Participated in architectural reviews to analyze system boundary isolation, structured logging, and automated dependency pipelines.
