I’m building a secure, privacy-first mental-health support platform inspired by BetterHelp and want an experienced partner to take it from concept to launch. The very first release must be fully functional in English, yet coded so additional languages can be rolled in without refactoring. Core experience The product centres on live, one-to-one HD video therapy sessions, real-time messaging/chat, and a completely automated appointment-scheduling flow that keeps therapists’ calendars and client reminders in sync. I also need an AI layer that can surface self-help resources, suggest next-step actions, and flag potential crises for clinical review—all while keeping user data encrypted at rest and in transit. Technical expectations Please architect for scale (micro-service...

I’m expanding our software engineering team here in Pakistan and want two strong full-stack engineers who are equally comfortable in ASP.NET and React.js. On any given week you might spin up a brand-new microservice in .NET 7, wire its UI in React + TypeScript, or dive into an older codebase to refactor and patch issues. Clean, well-documented commits and a habit of writing unit tests are essential because we ship continuously. Your day-to-day work will cover both building new applications and maintaining existing ones, and you’ll often be the first line of technical support when something goes bump in production—so clear, proactive communication is as important as your code. We collaborate in English on Slack and track work in Azure DevOps; experience with those (or sim...

Everything has to roll out at once, so I’m not looking for a phased approach: all ten connections have equal priority and need to be production-ready as soon as possible. I can supply API keys and sandbox accounts on ...
