    Feb. 2013 - present Medavail Technologies Senior Architect
    Mississauga, ON, Canada


    MedAvail was established from PharmaTrust through recapitalization after bankruptcy.


    As a Senior Architect, it is my responsibility to design and document architectural and system-level components, their interfaces, analyze use cases, and design database schema for the suite of applications at MedAvail. Establishment of organizational best-practices, designing efficient algorithms, and decomposing roles and responsibilities of software components to reduce overall system complexity, improve system robustness and maximize code re-use are also among my efforts. I report directly to, and work closely with the Chief Architect, and both provide oversight to the other development teams, as well as being very active in the code development, spending at least half of my time developing code as a member of various feature teams.

    Company overview

    MedAvail has developed a kiosk for remote dispensing of prescription drugs to an customer. The pharmacist is remote and interacts with the patient via telepresence involving audio/video link. Inside the kiosk is a dispensing robot that is responsible for choosing the correct package(s), labelling the medication, displaying imagery to the pharmicist to ensure quality control and safety requirements, printing the drug leaflets and other material, collecting payment, and finally releasing the package(s). Additionally there is a large enterprise software infrastructure for the administration of a collection of kiosks for large parmacy chain clients.
