IntermediateLEADERSHIP
On a recent project where you worked as a full-stack developer in a small team, how did you influence technical decisions (e.g., choice of frameworks, architecture patterns, or coding standards) and help keep frontend and backend work aligned?
Full Stack Developer
General

Sample Answer

On a recent project rebuilding an internal analytics dashboard, we had a team of four devs and a tight 10-week deadline. Early on, I pushed for us to standardize on a React + TypeScript frontend and Node/Express backend, both using the same TypeScript models. To get buy-in, I did a quick spike comparing this approach with our legacy stack and showed it cut boilerplate by about 25% and simplified onboarding. I also proposed a lightweight “API contract first” workflow. Before anyone coded, I hosted short design sessions where we defined OpenAPI specs for each endpoint and a shared data model. I wired up a mock server so frontend could build against real-looking data while backend finalized implementations. That kept us from drifting: we had one source of truth, shared linting/prettier configs, and a common error format. We shipped on time, and post-release bug tickets related to API/contract mismatches dropped by roughly 60% compared to the previous version.
