Built scalable, maintainable applications using TypeScript for over 5 years, with a focus on modular architecture, strong typing, and reusable components.
How do you approach integrating REST APIs in a front-end application?
Use fetch or Axios to make asynchronous calls, handle errors gracefully, normalize and cache data when appropriate, and abstract API logic into reusable services.
What strategies do you use to maintain performance in data-heavy web applications like ArcGIS Excalibur?
Implement lazy loading, virtual scrolling, code splitting, debounce/throttle input events, and optimize data-fetching with pagination or caching mechanisms.
How familiar are you with SASS and how do you organize styles in large projects?
Use SASS for modular, nested, and reusable styles; organize code using BEM methodology and structure styles by component and global utility.
Describe your experience with Git in a collaborative environment.
Follow GitFlow or trunk-based development workflows, use feature branches and pull requests, conduct code reviews, and resolve merge conflicts efficiently.
How would you ensure your code is scalable and maintainable in a collaborative project like Excalibur?
Write modular code, enforce linting and typing rules, add clear documentation and tests, and adhere to project-wide architectural patterns.
Can you describe a time you resolved a major front-end bug in a critical system?
Identified and fixed a rendering bug caused by improper state updates in a production app, added regression tests, and improved error monitoring tools.
Have you worked with mapping libraries or GIS technologies before?
Yes, worked with Leaflet and Mapbox for geospatial visualization, including layering, geocoding, and spatial querying; familiar with Esri’s APIs.
What’s your approach to debugging complex front-end issues?
Reproduce in isolation, inspect DOM/network via browser dev tools, add targeted logs, verify API responses, and use breakpoints to trace logic.
Why are you interested in working on ArcGIS Excalibur and what value do you believe you can bring to the team?
Excited by the mission-critical nature of spatial analysis tools; bring deep front-end expertise, API integration skills, and a passion for building user-focused solutions.
