What I'm looking for

I seek senior engineering roles building cloud-native, AI-integrated platforms with strong engineering culture, mentorship opportunities, scalable systems, and impact on product growth.

I am a senior software engineer with 10+ years building scalable web platforms and AI-powered systems, focused on delivering high-impact products used by millions of users.

I design cloud-native architectures and full-stack solutions using Python, Java, Ruby, JavaScript/TypeScript, and Go, and I lead work on distributed systems, RAG pipelines, and production ML integrations.

At OpenEvidence I architected an AI-powered medical search platform on Google Cloud, built large-scale evidence retrieval pipelines with Elasticsearch, and led cloud infrastructure efforts that improved uptime and reduced costs.

I mentor engineers, drive architecture initiatives, and implement CI/CD and event-driven microservice patterns to speed delivery and enable enterprise adoption.
