What I'm looking for

I seek senior engineering roles building AI-enabled, data-rich products in healthcare or consumer platforms at companies valuing collaboration, strong ML integration, cloud-native architectures, and measurable user impact.

I am a Senior Full-Stack Engineer with 8+ years building scalable, data-driven web platforms at Google, Microsoft, and Amazon, focused on healthcare data systems, applied AI/ML, and workflow automation.

I have led development of AI-enabled clinical tools and enterprise SaaS solutions—designing microservices, real-time streaming and search, and rich React UIs—resulting in measurable improvements in retrieval speed, accuracy, and clinician productivity across millions of records and users.

I collaborate closely with clinicians, data scientists, and product teams to deploy production ML integrations, optimize cloud architectures (GCP/AWS/Azure), and deliver reliable systems with strong observability and testing practices.
