I build reliable .NET and Apigee backend systems for enterprise airline and internal platforms.

I've delivered backend, integration, and reliability work for Cebu Pacific Air through Blackfort Consulting, supporting airline platforms, payments monitoring, and production operations. I execute zero-downtime deployments, investigate production incidents, and implement permanent automated fixes.

For Cebu Pacific's Cargo Rates Automation System, I helped re-architect services with Apigee pass-through architecture over an existing .NET Core backend. I've also integrated Apigee, Navitaire, and MongoDB for the Universal Account Management Portal, including fallback logic for outages.

At Blackfort Consulting, I build internal products including centralized user management connected to Microsoft Entra, a .NET MAUI and .NET Core asset-management solution with offline mode and ArcGIS integration, and Blackfort Tracker features for attendance, certificates, and leave filing.

I focus on maintainable, scalable services using C#, SOLID principles, Vertical Slice Pattern, and Clean Architecture. I've also automated CI/CD workflows and built .NET Core document-management modules for record management, user access control, and request tracking.
