🎯 Who is this job for?

This role is a strong fit for a full-stack engineer who enjoys working across React frontends and Java/Spring backends, thrives in fast-paced product environments, and wants meaningful ownership in building high-traffic web applications. It suits someone who is independent, detail-oriented, comfortable collaborating with cross-functional teams, and eager to expand their skill set while contributing to both feature development and performance improvements within a contract-to-hire setup.

💬 Potential Interview Questions

What technologies do you use for building full-stack web applications?
React with TypeScript and CSS/LESS on the frontend, and Java with Spring and Hibernate on the backend, exposing RESTful JSON APIs.
How do you translate a UI design into a functional React product?
I break the design into reusable components, use semantic HTML and CSS/LESS for styling, wire components to state and props, and ensure the implementation matches layouts and interactions from the design.
What is your experience with Java and Spring for backend development?
I build RESTful services with Spring Boot, using dependency injection for services and repositories, handle validation and error responses, and secure endpoints when needed.
How do you use Hibernate in a Java application?
I map entities to database tables with JPA annotations, use repositories or DAOs for data access, manage lazy/eager loading carefully, and optimize queries where necessary.
How do you structure a React + TypeScript application for maintainability?
I organize code by feature, define strong types for props and API responses, keep presentation and logic separated, and use hooks for shared behavior.
What’s your approach to designing and consuming REST APIs?
I define clear resource-oriented endpoints returning JSON, handle HTTP status codes correctly, document the API, and consume it via fetch/Axios in React with proper error and loading states.
How do you ensure performance and reliability in a full-stack application?
I avoid unnecessary re-renders on the frontend, cache or paginate data, write efficient database queries, add logging/monitoring, and include tests for critical paths.
What tools and practices do you use for source control and collaboration?
I use Git with feature branches, pull requests, code reviews, and a clear branching strategy, keeping commits small and focused.
How do you test your applications end-to-end?
I write unit tests for Java services and React components, integration tests for REST endpoints, and use tools like Jest or similar plus Postman for higher-level flows.
How do you handle production maintenance and bug fixing?
I use logs and monitoring to reproduce issues, create minimal test cases, fix the root cause, add regression tests, and deploy fixes with minimal user impact.
