MedLynk

Access Meets Action. MedLynk gives patients instant access to their health records, real-time AI guidance, and the ability to schedule real appointments seamlessly.

Inspiration

Access to health information should be simple and empower patients to take action. Too often, records are hidden, conversations are rushed, and critical mistakes happen. Inspired by the Patient Safety Technology Challenge, we wanted to give patients direct control: seamless access to their records, AI-assisted conversations, and real-time doctor scheduling — reducing diagnostic errors and putting the patient first.

What it does

MedLynk allows users to:

  • Instantly view their medical records
  • Chat naturally with an AI (Gemini) not only to understand their health data but also to help prepare for their upcoming doctor appointments
  • Save chat history to revisit important information anytime
  • Seamlessly book real appointments with their doctor via Calendly
  • Access everything securely from their phone

All in one HIPAA-conscious, mobile-first platform.

How we built it

  • Frontend: Built in React Native with Expo.io for mobile-first access.
  • Backend: Developed a Flask server deployed on Linux with Gunicorn, fully secured with Let's Encrypt certificates on medlynk.tech.
  • AI Chat: Integrated Gemini API to allow dynamic, medical record-based conversations, with persistent chat history support.
  • Scheduling: Connected Calendly’s OAuth2 API to enable real-time doctor booking inside the app.

Challenges we ran into

  • Configuring secure HTTPS routing with Let's Encrypt and real DNS management.
  • Setting up Calendly OAuth2.0 securely without leaking tokens or sensitive data.
  • Parsing large and varied PDF medical records for accurate AI conversations.
  • Managing seamless coordination between mobile app requests and backend authentication securely.

Accomplishments that we're proud of

  • Creating a real-world, secure healthcare platform with full HTTPS and custom domain deployment.
  • Achieving real-time medical record access and AI conversations inside the mobile app.
  • Seamless doctor appointment booking via Calendly OAuth — not just mockups, but a fully working flow.
  • Building a HIPAA-conscious, patient-centered tool that fits real healthcare needs.

What we learned

  • Deep experience building OAuth2 flows and real-time API integrations.
  • Hands-on deployment of mobile + backend systems at production-level security standards.
  • How direct record access and AI can help patients take control and improve healthcare outcomes.

What's next for MedLynk

  • HIPAA Certification: Strengthen encryption and data protection to meet full healthcare compliance.
  • Voice Integration: Allow hands-free booking and medical record conversations using speech-to-text and text-to-speech.
  • Doctor Portal: Launch a portal for doctors to view/manage patient questions and appointments.
  • Advanced AI: Expand Gemini’s use to prescription guidance, lab interpretation, and symptom checking.
