I am rolling out a Employee Assistance Program focused on mental health counselling and need a full solution that spans web, iOS, and Android. The core flow is simple: an employee browses confidential resources, chats live with a counselor, or books a future session— all from a clean, branded interface that HR can monitor through an admin dashboard. Key functions I must see working end-to-end: • Mental health counseling hub with tiered access to a resource library • Real-time, secure live-chat support that routes to licensed professionals • Calendar-based appointment scheduling with push/e-mail reminders on both mobile platforms and the web • App to facilitate secure phone and video counselling appointments Security, data privacy, and uptime are non-negotiable; please plan for industry-standard encryption and user authentication. The mobile apps must go live on both iOS and Android stores, and the website should mirror the experience responsively. When you reply, outline your proposed tech stack, development timeline, and any similar EAP or tele-health platforms you have built.
