Back-end Developer with 8+ years of experience building APIs, distributed systems, and scalable SaaS solutions using .NET Core and C#.

For the past 3 years at Pipa Studios, I've been working on a SaaS product running on AWS with Microsoft Orleans (Actor Model), ArgoCD, and complete CI/CD pipelines using GitHub Actions.
