What I'm looking for

I'm looking to build and own resilient backend and distributed systems, particularly event-driven services, cloud integrations, and high-volume transactional platforms.

At Grupo Universal, I lead solutions development across a microservices ecosystem, designing event-driven architectures on Azure and owning services from messaging topology and data modeling through deployment.

I've reduced API latency and transactional database load with Redis caching, rate limiting, session management, load testing, and defined SLIs. I also built payroll-to-Oracle HCM middleware using Azure Functions, Service Bus, Cosmos DB, and API Management with idempotent processing and reconciliation.

Previously, I built Odoo integrations, biometric-attendance ingestion systems, enterprise .NET integration layers, and a SAP connector. I enjoy building resilient distributed systems in Go and .NET, from CI/CD pipelines to production reliability.
