I built and deployed healthcare AI backend systems using FastAPI, RAG pipelines, and multi-agent LLM architectures on AWS to generate safer clinical documentation, reduce clinician workload, and improve decision-support accuracy in production healthcare environments.

I built LLM-powered financial analytics systems with RAG pipelines, semantic document search, and voice-enabled interfaces, enabling finance teams to query data faster while ensuring accurate, auditable outputs and scalable real-time performance.

I designed scalable backend APIs and AI-integrated data pipelines, deploying multi-tenant services on Amazon Web Services with strong monitoring, compliance validation, and workflow integration to deliver reliable, AI-driven business decision support.

I built full-stack logistics and operations platforms with real-time dashboards, microservices, and mobile apps, deploying scalable containerized systems on Microsoft Azure to deliver low-latency operational visibility and reliable production performance.

I built and optimized responsive JavaScript/TypeScript web interfaces with dynamic UI components, frontend testing, and performance tuning to improve user experience, stability, and engagement across customer-facing applications.
