Silvio Viana
@silvioviana
I build secure, high-performance backend systems with .NET, Python, Azure, and cloud-native services.
SpainWhat I'm looking for
At Upstart 13, I build .NET Azure Functions and Python geospatial workflows for US gas utility companies, processing thousands of survey batches daily. I replaced ArcPy with GeoPandas and parallel processing, making workflows 93% faster and saving about $5,000 annually in licensing costs.
Previously at Objective, I developed C#/.NET microservices and real-time fleet systems processing millions of vehicle events per day. I reduced BigQuery costs by 87%, improved a pricing API’s response time by 90%, deployed services across Kubernetes on GCP and Azure, and addressed critical production security vulnerabilities.
At Meta, I shipped .NET services, backend APIs, React dashboards, and university financial-data alignment workflows across seven campuses. I care about secure, observable systems that perform reliably at scale.
