Upgraded a legacy PC GUI system into a cross-platform web architecture for embedded environments, owning the core architecture, development, testing, and release lifecycle.

Key contributions

• Designed a cross-platform web service architecture for Linux ARM, Linux x64, and Windows, driving the migration from a legacy PC GUI to a web-based system.
• Developed .NET RESTful APIs and a Blazor-based web GUI with reusable frontend components.
• Designed an internal HTTPS/SSL certificate issuance solution to secure communication in internal environments.
• Built a regression testing system for legacy WCF services and new Web APIs through standardized shared contracts and reusable test workflows.

Led stability inspection for custom development services by analyzing potential risks from service metrics, dump analysis, and incident reviews.

Key contributions

• Analyzed service metrics to identify potential risks and drive early issue tracking.
• Performed dump analysis, exception investigation, and incident reviews when service issues occurred.
• Upgraded shared frameworks and components to improve reliability, maintainability, and distributed service coordination.

Built foundational framework capabilities for customer-specific delivery scenarios and encapsulated reusable Infrastructure patterns for multi-tenant consistency, runtime reliability, and easier troubleshooting.

Key contributions

• Built framework foundations for tenant isolation, context management, and log tracing in custom development scenarios.
• Encapsulated the Infrastructure layer to provide resilience policies, distributed locks, and reusable platform capabilities.
• Standardized request context, tenant context, and log tracing to reduce cross-module development and troubleshooting cost.
• Provided reusable foundations for later custom development, service refactoring, and task orchestration work.

Participated in the assessment, development, and delivery of customer-specific HR SaaS projects covering organization, performance, and goal management modules.

Key contributions

• Designed Kafka data-change trigger abstractions to cover missing business trigger scenarios.
• Refactored service architecture and infrastructure components to address business complexity and improve service stability.
• Standardized unit testing, development, testing, release, and CI/CD workflows to improve delivery quality and engineering efficiency.

Refactored master data synchronization and Kafka-based messaging to improve data consistency, asynchronous processing, and service stability.

Key contributions

• Optimized master data synchronization to reduce cross-service consistency risks.
• Improved Kafka-based messaging workflows for asynchronous processing and task scheduling.
• Designed SSO cloud migration solutions and encapsulated the Beisen SSO SDK to standardize authentication integration.

Developed and iterated the goal management system within Beisen’s HR SaaS platform.

Key contributions

• Introduced an IoC framework and unit test protection to support safer legacy code refactoring.
• Refactored business modules to improve maintainability, extensibility, and delivery quality.
• Continued backend capability and service API iteration around goal management workflows.

Developed a full-stack field workforce management system supporting outdoor attendance check-in, location tracking, and field activity records.

Key contributions

• Built Vue/HTML frontend pages, ASP.NET MVC backend features, and WCF service interfaces.
• Implemented MySQL data access with Dapper ORM.
• Covered full-stack delivery across frontend interactions, backend services, and database access.
