What I'm looking for

I’m looking to build scalable, responsive web applications with modern React/Angular and .NET Core—where I can drive innovation, integrate AI and APIs, and deliver reliable backend services that support business growth.

I’m a full stack developer specializing in building dynamic web applications using React, Angular, and .NET Core. I focus on backend development to deliver scalable and responsive solutions, and I’m driven by innovation and efficiency through modern technologies.

In my recent role as a .NET ENGINEER / C# Developer (Codev Philippines), I maintain and develop back-end/.NET Core systems, including integrations for Chat Bot AI, Azure OpenAI, and ADX. Previously, as a Back End Engineer at SnapSuite (remote), I maintained and developed back-end integrations using ASP.NET Core, Azure Functions, and Service Bus.

I’ve also worked across API integration and UI development (ASP.NET Core/MVC, NEXT JS, and Vue JS), and I’ve contributed patterns and reliability through Domain Driven Design, Entity Framework, background jobs with Hangfire, and data access with Dapper. Earlier experience includes Angular UI, WordPress support, SignalR realtime data, and Android/Java development, as well as migrating legacy projects into .NET Core.
