When debugging a complex web application, I start by clearly defining the problem and reproducing the issue consistently. I note what’s happening, what should be happening, and the conditions under which the bug appears (browser, device, user flow, environment). From there, I break the application down into smaller pieces and isolate where the issue is occurring—whether it’s frontend behavior, backend logic, API responses, or data handling. I use browser developer tools, logs, and network requests to trace errors and understand where things are breaking.

For full stack development, I prefer modern, widely adopted technologies that prioritize scalability, performance, and ease of collaboration. On the frontend, I’m a fan of React (often with Next.js) because it enables fast, responsive user interfaces and works well with component-based design systems. On the backend, I value Node.js with Express or Python-based frameworks like Django or FastAPI for their flexibility and strong ecosystem support. For databases, PostgreSQL is a go-to for reliability and structure, while MongoDB works well for more flexible data needs. I also appreciate teams that use tools like Git/GitHub for version control, REST or GraphQL APIs, and cloud platforms such as AWS or Vercel to streamline deployment. Overall, I look for tech stacks that support clean architecture, easy testing, and smooth collaboration between engineering, product, and content teams.

I ensure accuracy when reporting bugs by being as specific and repeatable as possible. I start by clearly documenting the exact steps taken before the issue occurred, including device type, operating system, app version, and whether the bug happens consistently or intermittently.
