Sajankumar – AWS, Python, React

A software which transforms static documents like PDFs, Excel models, scanned contracts, and images into an intelligent, searchable knowledge base.

• Created front-end and back-end architecture.
• Configured RAG and Vertex embeddings.
• Built deployable chatbot.
• Implemented voice integration.
• Configured payments and subscriptions along with complete k8s infrastructure with Tailscale.
• Configured complete CI/CD via Github workflow.

A high-concurrency voice agent integrated via real-time API with Practice Management Software (Dentrix, Curve). An intent recognition layer differentiates clinical emergencies from routine bookings and routes each appropriately. The agent reads live calendar availability to confirm appointment slots inside the same call. A sentiment-detection layer monitors caller frustration and triggers an instant SMS escalation to the human receptionist when the conversation exceeds its confidence threshold.

• Successfully plugged a "revenue leak" by capturing inquiries that previously went unanswered outside of business hours leading to 40% increase in after-hours lead capture.
• Automated repetitive scheduling tasks, significantly lowering the administrative burden on receptionists which led to 15% reduction in staff burnout.
• Freed up staff to prioritize high-value, in-chair patient care rather than managing phone lines leading to enhanced clinical focus.
• Achieved continuous, 24/7 operation with zero incremental labor costs per patient interaction.
