Roger Barreto
Summary
🤩
RockstarRoger Barreto is a Principal Software Engineer based in Greater Dublin with over a decade of hands-on experience building developer-facing foundations and cloud-native AI integrations. He has been a founding .NET engineer on Microsoft’s Agent Framework and a core contributor to the Microsoft Semantic Kernel, designing abstractions for streaming, chat completions, plugin architectures and multiple AI connectors. Roger brings deep operational rigor—owning SDK maintenance, dependency hygiene, security fixes and OpenTelemetry-driven observability—to ensure platform stability and forward compatibility at scale. His work spans cloud integrations across Azure AI Foundry, Anthropic, OpenAI, Gemini and Bedrock, and he has led migration and developer experience improvements that eased adoption for existing Semantic Kernel users. Earlier in his career he combined product engineering, automation and DevSecOps across enterprises and startups, from IoT solutions to e-signature and CRM platform work. Colleagues describe him as an engineer who prefers building the foundations others stand on—balancing low-level reliability with pragmatic developer experience.
