Senior Developer (Front-End)

This position is suited for a senior front-end engineer with deep React and UX expertise who wants to lead the development of complex, dynamic, and highly interactive interfaces—particularly form builders, drag-and-drop systems, and component-driven architectures—in a cloud-focused, government-oriented environment. It fits someone who enjoys blending technical leadership with hands-on implementation, collaborating on human-centered design, maintaining strict design and security standards, and driving scalable UI solutions within Agile and DevSecOps practices.

1. How do you approach building dynamic, schema-driven forms in React for complex UX requirements?
   I usually design a JSON-based schema that defines fields, validation, conditional visibility, and layout, then build a generic FormRenderer that consumes the schema. This allows non-developers or configuration to drive form changes while keeping React components reusable and testable.

2. Can you describe how you apply Human-Centered Design principles when building new UI flows?
   I start with understanding user goals and constraints through research or stakeholder interviews, then create low-fidelity prototypes to validate flows early. I iterate based on usability feedback, focusing on clarity, reducing cognitive load, and ensuring the interface supports real user workflows, not just business assumptions.

3. How do you implement drag & drop card interfaces in React while keeping state predictable and accessible?
   I use a library like React DnD or @dnd-kit, modeling state as an ordered list of items and updating it immutably on drag events. I also ensure keyboard alternatives and ARIA attributes are present so the interaction is usable beyond mouse/pointer devices.

4. What’s your strategy for structuring a React application with component-based and event-driven architecture?
   I organize by feature/domain, encapsulate UI and logic in well-defined components, and use events or callbacks to decouple components where direct props drilling would create tight coupling. For larger systems, I use pub/sub patterns or context/event buses carefully to keep responsibilities clear.

5. How do you choose and manage state with tools like Redux or Context API in a large front-end codebase?
   I keep most state as local as possible, reserve Redux or similar for cross-cutting/global concerns, and use slices/selectors to avoid over-coupling components. I’m careful to separate server state (often via query libraries) from client UI state, and I measure performance impacts of global updates.

6. How do you ensure performance and scalability of a React/Tailwind application in a cloud environment such as Azure?
   I focus on code splitting, lazy loading heavy routes, minimizing re-renders, and using Tailwind’s JIT to keep CSS bundles small. On Azure, I leverage CDN, caching headers, and proper build pipelines, then monitor real-user metrics to drive targeted performance improvements.

7. How do you integrate DevSecOps principles into your front-end development workflow?
   I embed security checks into CI/CD with dependency scanning, linting, and basic SAST, enforce code reviews with security in mind (XSS, CSRF, injection), and ensure secure configuration of environment variables and build artifacts. I treat security issues like any other defect with clear ownership and remediation paths.

8. Describe how you would lead a code review for a new UX-heavy feature built in React and TypeScript.
   I review for correctness, accessibility, and UX fidelity first, then check type safety, component boundaries, and test coverage. I give specific, constructive feedback, ask clarifying questions where intent isn’t clear, and highlight positive patterns to encourage consistency across the team.

9. How do you collaborate with UX designers when implementing Human-Centered Design in a government or public-sector context?
   I engage early in design discussions, translate their wireframes into technical constraints and opportunities, and provide feedback on feasibility and performance. Throughout implementation, I validate UX assumptions with stakeholders and, where possible, user testing, adjusting the UI to meet both policy and user needs.

10. How do you handle accessibility and design standards in a long-lived enterprise or federal front-end project?
    I align with established design systems and accessibility standards (WCAG, Section 508), build reusable components that encode those standards, and use automated and manual accessibility testing. I document patterns and enforce them via linting, code review, and Storybook or similar component catalogs.
