🎯 Who is this job for?

This role is ideal for a Middle Full-Stack Developer with 4+ years of experience building web applications using React, TypeScript, Node.js, and PostgreSQL. It suits someone comfortable developing scalable full-stack features, integrating third-party APIs, deploying on AWS, and maintaining clean, testable code in an Agile environment. You should enjoy collaborating with product and clinical teams, handling sensitive healthcare data responsibly, and exploring AI-powered features to improve digital health platforms.

💬 Potential Interview Questions

How would you design a scalable full-stack architecture for a digital health platform using React, Node.js, and PostgreSQL?
I would separate the system into modular services with clear API boundaries, using Node.js for backend services and PostgreSQL for structured patient and operational data. The frontend would use a component-driven React architecture to ensure maintainability and scalability.
How do you ensure security and compliance when building healthcare applications that handle sensitive data?
I implement secure authentication, encryption in transit and at rest, strict access control, and thorough input validation. Following HIPAA-aligned practices and minimizing exposure of sensitive data are essential in healthcare systems.
How would you integrate third-party services such as scheduling, billing, or communication APIs?
I build dedicated integration layers that handle authentication, error management, and rate limits. Clear abstraction layers allow us to swap or extend integrations without affecting the core application.
How do you structure React applications to support complex user flows like patient onboarding or care management?
I design reusable components, organize code by feature modules, and separate business logic from UI. This keeps workflows maintainable as the application grows.
What is your approach to designing and maintaining RESTful APIs for a full-stack application?
I define clear endpoints with proper validation, consistent response formats, and strong error handling. Versioning and documentation help ensure APIs remain stable as the system evolves.
How do you deploy and manage applications on AWS?
I use services like EC2 for compute, RDS for relational databases, and S3 for storage, combined with CI/CD pipelines for automated deployment. Monitoring and logging ensure reliability in production.
How would you implement AI-powered features in a healthcare application?
I integrate AI services through controlled APIs, ensuring data privacy and transparency in AI outputs. AI can assist with recommendations, automation, or insights while keeping clinicians in control.
How do you maintain high code quality in a distributed remote team?
I use code reviews, automated testing, and consistent coding standards. Clear documentation and proactive communication help maintain alignment across remote teams.
How do you approach debugging issues that occur across both frontend and backend systems?
I trace the request flow from the client through APIs to the database, using logs and monitoring tools to identify bottlenecks or failures. Once the root cause is identified, I implement targeted fixes and add safeguards.
How do you balance speed and reliability when building early-stage healthcare technology?
I prioritize delivering impactful features quickly while maintaining clear architectural boundaries and test coverage. This ensures rapid iteration without compromising stability or patient trust.
