Senior .NET Developer at BuBiBo building veterinary SaaS finance flows and document-generation pipelines.

Portugal

Message

At BuBiBo, I design and develop business modules for a multi-tenant, multi-region veterinary SaaS. I built financial and payment flows with complex calculations and strict consistency requirements.

I also developed document-generation pipelines using dynamic templates and HTML-to-PDF rendering, with real-time status updates over SignalR. I implemented asynchronous service communication with Azure Service Bus and the transactional outbox pattern.

Previously, I developed backend services and React features for an AI-powered dating application, and delivered features and bug fixes for a video service for creating and promoting content. My work has included .NET, CQRS/MediatR, PostgreSQL, and AWS integrations.
