At BlastAsia Inc., I design and develop enterprise web applications for a multi-portal ecosystem using C#, ASP.NET, and a layered ADO.NET architecture.
I build and maintain REST APIs and SQL Server stored procedures for cross-portal data exchange, search, filtering, and reporting. By optimizing SQL queries and application workflows, I reduced system latency by 30%.
At First Life Financial Co., Inc., I developed and supported internal enterprise systems using ASP.NET Web Forms, C#, and Oracle, and resolved defects to reduce downtime and improve reliability.
Earlier, at Equitable Computer Services, Inc., I designed and maintained WinForms and Web Forms applications, translated business requirements into working software, and authored technical documentation.
