Paulo Henrique

I’m a full-stack Software Engineer specializing in C#/.NET and cloud-native, event-driven architectures. I build scalable, maintainable backend systems and reliable RESTful APIs, modernizing legacy codebases with CQRS and Mediator patterns.

At BMPTec, I modernized a legacy C# ASP.NET Core API to .NET 8 using CQRS and Mediator patterns, simplifying the API layer and improving maintainability. I introduced automated unit testing with xUnit and integrated it into Azure DevOps CI, reaching 100% coverage and catching regressions earlier to increase deployment confidence. I also migrated four asynchronous processing routines to AWS Lambda with an event-driven design, improving performance by ~47% and enabling elastic scaling.

I enjoy translating complex workflows into dependable automation—designing REST/JSON message mediation to reduce integration errors and leading a Vue.js + .NET Core regulatory system that automated ~75% of manual work. I’ve also refactored a mission-critical data processing pipeline aggregating 500M+ records/month, cutting end-to-end time from ~6 hours to ~1.5 hours and reducing cloud costs by ~75% per run, while consistently applying SOLID principles in Agile environments.
