  • MedPics
    Chief Technology Officer | Accelerator for collaborative and secure scientific sharing | Digital medical staff
    June 2014 - January 2019 (4 years and 7 months)
    Arrondissement de Montpellier, France
    Co-founder of MedPics: The 1st mobile app for secure sharing of clinical cases and therapeutic protocols. MedPics Enriches, Augments & Facilitates digital communication for healthcare professionals. The MedPics application was born from the reflection of Dr. Safia Slimani, an emergency and general practitioner, who on numerous occasions encountered clinical cases (in her practice or in hospital departments) that required multidisciplinary collaboration for their resolution. She initially used traditional social networks as the primary means of communication with her peers. It was long, very long, as it required gathering interested professionals, sending them the case through unconventional and insecure transmission methods, and waiting for their feedback... in short, a real chore to aggregate information for efficient diagnosis. Frustrated by the time it took to sometimes get only a rough answer, Safia conceived the framework for the MedPics application. The challenge was to bring together in a single network healthcare professionals capable, through their enriched experiences, of sharing, interacting, and instantly deciding on:
    • Management of clinical cases in MCO (Multi-disciplinary care) and SSR (Rehabilitation and follow-up care)
    • Therapeutic protocols to disseminate
    • Diagnoses made, images, or reports such as DICOM, ECG, EEG, etc.
    • Initial training for students and refresher courses for practitioners
    To ensure the ethical rules of scientific sharing by respecting:
    • Data transmission security
    • Medical confidentiality
    • Patient anonymity
    I was immediately captivated by the desire to bring a digital dimension to scientific exchanges. It was natural for me to join the team to build the technical ecosystem of MedPics.
