Senior Full-Stack Developer — Mediqor Clinical System (MCS) Location: Philippines only (remote) Engagement: Freelance, monthly retainer Start: Immediate --- About the Project Mediqor is a bilingual (Arabic + English) healthtech platform built for the MENA region (Middle East & North Africa). The backend is a multi-tenant microservices system called the Mediqor Clinical System (MCS), deployed on Azure Container Apps. It serves multiple healthcare providers (HCPs) under their own branded subdomains (e.g. [login to view URL]), with a shared identity layer, role-based access control, and a patient-facing mobile app built in React Native / Expo. The system supports patient registration and consent, doctor and staff onboarding, appointment scheduling, video consultations ([login to view URL]), an encrypted clinical vault, AI-driven health triage (Claude API), a subscription and billing engine (Stripe), and an admin portal for Mediqor staff. The platform is being built toward an IPO milestone with a hard deadline of October 2026. --- What You’ll Be Working On The core infrastructure is live and Phase 1 is complete. You’ll be joining to help finish and harden the remaining phases: - Complete remaining MCS microservices (directory, scheduling, clinical records, diagnostics) - Expand the React Native / Expo mobile app for patients and clinicians - Build and maintain the tenant-facing admin web portal (React + Vite) - Write integration tests, API tests, and end-to-end test coverage - Support CI/CD pipelines (GitHub Actions, Azure Container Registry, ACA deployments) - Work alongside an AI-assisted development workflow using tools like Claude Code and Codex With Claude Code (Claude CLI) as the primary dev environment, I'm not looking to hire someone who can write React. I'm looking for someone who can: * Decompose a problem clearly enough to direct an AI agent * Review AI-generated code critically (catch hallucinated APIs, wrong patterns, security issues) * Write good prompts and specs * Debug when the AI goes sideways * Know when to stop prompting and just write the code themselves But more importantly, a true Engineer who thinks and understand the product we are building and why we are building this product. This is not a one off project. We are looking for someone that will be with us for long term. Experience with multi-tenant SaaS architecture - Familiarity with healthcare data privacy (PDPL, HIPAA concepts) - [login to view URL] or other WebRTC video SDK experience - Stripe subscriptions and webhook handling --- Engagement Details - Monthly retainer — rate negotiable based on experience - Remote / async — core overlap with UAE timezone preferred but flexible - Philippines-based applicants only - Long-term engagement — this is a growing platform with a roadmap through 2026 and beyond - Freelancer must have strong history on Freelancer.com with mid-level to senior experience. -Freelancer must be able to start working immediately with little to no guidance. -Freelancer must have access to Claude Premium seat and MacOS. -Freelancer must be available during Philippine business hours. How to Apply Please include: 1. A brief intro — your relevant experience with FastAPI, React Native, and Azure 2. One example of a project you built or maintained that had a mobile + backend + cloud stack 3. Your preferred monthly rate (USD) 4. Confirmation that you are based in the Philippines

Hi there Systems like this don’t fail on features, they fail when multi-tenant logic, real-time workflows, and integrations start conflicting under production load. I’ll approach this by treating MCS as a coordinated system -FastAPI services, PostgreSQL with RLS, React/Expo apps, and Azure deployments - so each layer remains consistent, secure, and scalable as new modules are completed. This means I understand how patient flows move end-to-end: registration, scheduling, consultation, records, billing, and AI triage, all tied together through stable APIs and controlled infrastructure. My process is simple: first align on current service gaps and priorities. Then complete and stabilize backend services and integrations. Finally, expand mobile/web apps and strengthen CI/CD, testing, and monitoring. Final timeline and budget will be defined precisely once responsibilities and workload are confirmed. If this aligns with you, let’s discuss in detail via private chat.

Hi, SolutionzHere here, we work extensively on healthtech SaaS with FastAPI microservices, React Native/Expo apps, and Azure-native deployments. We align strongly with your “AI-assisted engineering” mindset: structured decomposition, prompt-driven workflows, critical review of AI-generated code, and hands-on debugging when automation fails. Experience includes HIPAA-aware systems, Stripe billing, WebRTC/video flows, and multi-tenant RBAC on Microsoft Azure. Preferred monthly retainer: $4,500–$6,000 USD depending on workload intensity. One key question: Is the current architecture/event flow documented well enough for immediate onboarding, or should we expect an initial reverse-engineering phase?

Hi, I understand you’re prioritizing Philippines-based engineers, but I’m reaching out because this aligns closely with the kind of systems I’ve worked on. This is not a typical full-stack role—it’s about owning system behavior across microservices, mobile, and AI-assisted workflows, which is where most teams struggle. My experience covers: → FastAPI / Node backends with structured service layers → React Native apps with production deployment → Cloud infrastructure (AWS/Azure-style setups, CI/CD pipelines) → Stripe subscriptions, webhooks, and state consistency → Working with AI-assisted dev workflows (reviewing, correcting, and guiding generated code) I’m comfortable working in environments where AI tools are part of the workflow, but decisions, debugging, and architecture still require engineering judgment. I’ve worked on platforms where data integrity, user roles, and system reliability were critical, so the focus here would be contributing as an engineer who can think through the system, not just execute tasks.

Hello, I’ve worked extensively with FastAPI-based microservices, React/React Native applications, and cloud-native deployments, and your Mediqor platform aligns closely with systems I’ve built in multi-tenant and healthcare-adjacent environments. I’m comfortable working across the full stack — from async backend services (FastAPI + PostgreSQL with structured schema design) to mobile apps (React Native / Expo) and CI/CD pipelines on Azure. I also actively use AI-assisted development tools like GitHub Copilot and Claude-style workflows in daily development, especially for accelerating testing, refactoring, and API integration tasks. I have experience designing scalable APIs, handling authentication (JWT, RBAC), and integrating third-party services like Stripe and video SDKs. One relevant project involved building a mobile + backend system with role-based access, real-time workflows, and cloud deployment, where I handled both backend services and frontend integration. Preferred monthly rate: $2800 USD Based in the Philippines: Yes Available to start immediately and work long-term. Best regards, Srdjan Njegovan

This project is right in line with the projects I work on and fits my experience well. I am familiar with building multi-tenant microservices using FastAPI and async SQLAlchemy while handling complex role-based access control. The combination of React Native mobile app expansion alongside robust CI/CD pipelines on Azure often requires close attention to integration test coverage, which is sometimes overlooked. I would focus on clear documentation and testing to keep development smooth and code reliable as the platform moves toward its IPO milestone. Reach out for a free consultation, happy to share a clear next step with no expectations. Stef
