Tell me about a time you influenced technical strategy or roadmap for front-end work (e.g., adopting TypeScript, design systems, or CI/CD). How did you present the case, gain stakeholder buy-in, and drive execution?

Sample Answer

At my last company I noticed onboarding bugs and inconsistent UI slowed feature delivery by ~25% across a 7-person front-end team. I led an effort to adopt a design system plus TypeScript to reduce runtime errors. I collected concrete data—bug counts, time-to-merge, and dev onboarding hours—then prototyped a shared component library (12 components) and converted a high-risk module to TypeScript as a demo. I presented cost/time tradeoffs to product and engineering leadership, showing an estimated 30% drop in UI bugs and a 20% faster onboarding. With a roadmap, weekly demos, and paired work sessions, we shipped the library in three sprints. Within six months we saw a 35% reduction in UI regressions and new dev ramp time drop from 3 weeks to 9 days.
