What I'm looking for

I’m looking to build and scale cloud-native, AI-powered platforms where reliability, automation, security, and operational excellence matter—working on backend infrastructure, real-time processing, and observability-driven improvements in a collaborative engineering culture.

I’m a Senior Software Engineer with 11 years of experience building large-scale AI platforms, fintech systems, cloud infrastructure, and distributed systems at Anthropic and Google. I focus on delivering scalable, high-performance, production-ready systems with an emphasis on reliability, automation, security, and operational excellence.

At Anthropic, I’ve owned end-to-end delivery of AI infrastructure and backend platforms supporting Claude model operations, enterprise integrations, and agentic AI workflows across cloud-native environments. I build distributed services and real-time data pipelines using Python, Go, TypeScript, Kubernetes, AWS, and gRPC, and I strengthen production visibility through observability work with Datadog, Prometheus, Grafana, OpenTelemetry, and CloudWatch—while also automating engineering operations with LangChain, MCP integrations, and API-driven workflows.
