Featured Project 01

AI Medical Appointment Booking Agent

100%
autonomous booking flow
The Problem

Manual scheduling created friction and no after-hours self-service for patients.

The Solution

A conversational agent — by chat or voice — collects details, checks real-time doctor availability, books automatically and confirms, retaining history end-to-end.

Next.jsVoice AgentLLMn8nCalendar APINotifications
Impact

Round-the-clock self-service booking with zero manual intervention and full conversation history.

AI-Powered Recruitment Automation Platform

3
specialized AI agents
The Problem

High-volume screening is slow, inconsistent and expensive to do manually.

The Solution

Three specialized agents work in sequence — a Resume Parser extracts structured data, a Technical Assessor scores against the JD, and a Decision Agent makes the final shortlist or reject call automatically.

Impact

Consistent, explainable shortlisting that scales screening without adding headcount.

SmartDocs AI — Enterprise RAG Platform

Cited
answers
The Problem

Knowledge is locked in long documents; keyword search can't answer real questions or prove its sources.

The Solution

A production RAG platform on FastAPI & LangGraph: upload PDFs, query in natural language, and get context-aware answers with source citations — built for scale and real-time processing.

Telehealth Platform — Connected Care

4
stakeholders connected
The Problem

Care is fragmented — patients, doctors, insurers and researchers work in silos, which hurts treatment adherence and access.

The Solution

A single secure platform that connects all four stakeholders, using voice AI to make care delivery smarter and more accessible — helping patients stay on track with treatment and stay safe.

Venue Discovery — Self-Serve Onboarding

Self-serve
owner onboarding
The Problem

Onboarding venues manually is slow and bottlenecked — owners can't get listings live or keep them current on their own.

The Solution

A venue onboarding platform that lets property owners independently register, manage and update their listings — with profile creation, image uploads, availability management and pricing updates.

Impact

Faster onboarding and always-current listings — owners stay in control without any manual intervention.
