Message

At HDBank, I develop RESTful APIs for biometric unlock and outbound remittance requests using .NET Core and Entity Framework Core. I also optimize PostgreSQL databases and apply security practices such as JWT and input validation.

Previously, at DHL Express, I worked on shipment management APIs and integrated services including SSO, RabbitMQ, and SignalR. At AtMAN VINA, INC., I worked on a warehouse management system for the NIDEC VIETNAM project, supporting API development, database optimization, and deployment.
