What I'm looking for

I'm looking to build and modernize scalable cloud platforms, solve distributed-system challenges, and work closely with product, security, QA, and stakeholder teams to deliver reliable, high-impact software.

I've built and modernized scalable backend platforms across Authority Partners, Crowd Analyzer, and Extend Ad Network using C#, .NET, Azure, SQL Server, and event-driven architecture.

At Authority Partners, I migrated legacy .NET projects to .NET Core, modernized Azure Functions, and supported an IAM migration from ForgeRock to Auth0 for a platform serving 1.4M users. I also resolved integration and performance issues across distributed systems processing more than 8M requests per day, while improving login and sign-up flows with React, ForgeRock, and PingOne.

At Crowd Analyzer, I built Crowd Ads from scratch as an event-driven microservices platform, designed scalable Azure architecture, and developed its Angular admin application. I also delivered an AWS-hosted video streaming solution using S3, MediaConvert, and CloudFront, alongside Paymob subscription billing.

Previously, I built backend architecture and REST APIs for Platraw and developed core services for LAVAD, including Azure Functions, SQL Server, Redis, and a transition from monolithic architecture to microservices. I bring hands-on experience delivering reliable customer-facing and internal applications in close collaboration with product, security, QA, and stakeholder teams.
