Jason Chu

Built robust backend services with .NET Core and C#, developed RESTful APIs with authentication and versioning, and migrated legacy applications into microservices architecture. Prototyped Blazor WebAssembly components, optimized SQL Server and Redis caching for high-load workflows, and created dynamic SPAs with Angular and RxJS. Led CI/CD implementation using Azure DevOps, integrated Azure Cognitive Services for image tagging and sentiment analysis, provisioned Azure infrastructure, and incorporated Playwright for end-to-end testing. Integrated Azure OpenAI GPT models for internal support tools, led team coding standards, mentorship, and partnered with stakeholders for sprint planning.

Led architectural innovation and front-end modernization using .NET technologies and Agile. Designed microservices with .NET 8 and Docker, improved SQL Server stored procedures, developed message-driven services with RabbitMQ, applied CQRS with MediatR, rebuilt Angular dashboards with SignalR, tested Blazor components, integrated Selenium for regression testing, and implemented speech-to-text transcription with Azure Speech API. Evaluated Terraform for provisioning, developed internal chatbot with Azure OpenAI, utilized AWS Lambda and S3 for compute and content delivery, implemented observability with Serilog, Application Insights and Prometheus/Grafana, enforced code coverage, automated data reconciliation, integrated third-party APIs, introduced automated testing frameworks, developed feature flagging with LaunchDarkly, and acted as technical lead.

Transformed legacy monolithic architecture into microservices with ASP.NET Core, adopted Entity Framework Core, implemented gRPC APIs, revamped support dashboard with Angular and TypeScript, integrated SignalR, transitioned tools to React with Material-UI and Redux, modernized with Knockout.js and Bootstrap, consolidated authentication under OAuth 2.0 and JWT, moved credentials to Azure Key Vault, containerized services with Docker, automated regression testing with Selenium, developed unit tests with xUnit and Moq, optimized performance using Redis caching, enforced code quality with SonarQube, designed SSRS reports, optimized SQL Server and Oracle queries, leveraged LaunchDarkly for feature management, and updated relational schemata to meet ACID compliance.
