Experienced .NET developer specializing in scalable web applications and modular architecture.
PhilippinesWhat I'm looking for
I am a .NET developer with under three years focused on .NET/.NET Core and extensive hands-on experience building modular, high-concurrency web applications. I design and implement role- and claims-based authorization, optimized data access with EF Core and LINQ, and reusable modules to accelerate feature delivery.
At MyBusyBee Inc I led architecture and development for a nationwide DENR information system, delivering large-scale proposal lifecycle management, complex permission models with 100+ granular permissions, and server-side optimization for large datasets. I manage deployment, IIS configuration, SQL optimization, and production support.
My background also includes full-stack projects, freelance .NET Core work for real estate and inventory systems, and earlier SAP ABAP and web development experience. I focus on clean architecture, reliable transaction-safe operations, and delivering maintainable code that meets operational needs.
