My current application depends on a custom Java-based WebRTC layer. I now need the same real-time capabilities rebuilt natively in Angular so the front-end team can iterate faster and keep everything in a single tech stack. Scope of work The new Angular module must handle plain audio calls, full HD video calls, and our existing “virtual classroom” flow that lets tutors and students join at scheduled times. Beyond parity with the Java version, I also want integrated screen sharing, an in-session chat panel, and the ability to record each session for later playback. All features have to work smoothly on desktop, mobile, and tablet browsers. Tech notes • Angular 16+ with TypeScript best practices • Direct use of WebRTC APIs—no server-side medi...

...day-to-day. The immediate focus is front-end development, so you’ll be steering our React and layers—building reusable components, wiring pages to the router, and tightening up state management. While the UI comes first, we will also expose fresh endpoints as we go; you’ll help shape the Node.js / API that feeds those screens. We already have a rough domain model running in Java micro-services, so expect to consume and occasionally extend those services rather than start from scratch. Clean, well-tested code, Git-based collaboration and clear commit messages are essential because we’ll be working side-by-side and merging often. Deliverables (acceptance criteria) • Pixel-perfect React/ pages that match Figma references and render responsively. ...

Robust back-end thinking is important too; whether you prefer Firebase, AWS Amplify, or another scalable service, please outline how you’ll handle user authentication, real-time feed updates, and media storage. To keep us focused, here’s what I expect at each milestone: • In...

I’m ready to move from concept to code on a Java web application and I need a developer who feels at home in JavaServer Faces. The entire project will live in the Java EE ecosystem, so comfort with standard servlet containers, JDBC or JPA for data access, and front-end component libraries such as PrimeFaces or OmniFaces will be important. Here’s what I’m looking for you to handle: • Set up the JSF project structure (Maven or Gradle) • Build the core pages and managed beans that showcase best-practice navigation, validation, and session handling • Wire in persistence so the app reads/writes to a relational database (MySQL or PostgreSQL—your recommendation is welcome) • Implement basic security: login, role-based access, and ...

Our engineering organization is doubling down on shift-left quality, and the next milestone is a fully automated test suite that lives alongside the codebase and runs on every commit. The work spans strategy, hands-on coding, and mentorship. You will craft an automation framework in Selenium, writing suites in Python, Java, and JavaScript—whichever language best fits each micro-service. Functional coverage comes first, followed quickly by performance scenarios that exercise real-world concurrency and data volumes. Each suite must plug into our existing CI/CD pipeline so that failures block the build and generate actionable reports for developers inside their pull requests. Key targets include: • Converting current manual regression cases into reliable Selenium scripts...
