What I'm looking for

I seek roles building production-grade AI/ML and LLM systems with strong MLOps, collaboration with product and compliance teams, and cloud-native scale.

I am a Senior Python engineer and AI specialist with 8+ years building scalable backend systems, production ML pipelines, and cloud-native applications across Healthcare and FinTech. I design HIPAA-compliant platforms, multi-tenant SaaS, and RAG/LLM solutions using LangChain, HuggingFace, AWS Bedrock, and Azure OpenAI, delivering measurable improvements in latency, accuracy, and automation.

I have led end-to-end MLOps implementations with CI/CD, model versioning, drift detection, and observability, and shipped production services supporting hundreds of thousands of concurrent users. I partner with product, clinical, and compliance teams to ensure secure, reliable, and high-impact AI deployments that improve user outcomes and operational efficiency.
