FAQ: JavaScript Developers
1. What technical skills should I hire for?
Seek ES6 and TypeScript skills. Prefer React or Vue experience and knowledge of Webpack, ESLint, and VS Code for build and QA workflows. Require 3+ years in e-commerce or fintech projects with Jest testing.
2. How fast can Staffenza deliver hires?
Staffenza sources vetted candidates quickly. Expect shortlisted React, Angular, or Vue developers in 7-21 days. Start with a 2-week paid trial and set clear onboarding milestones.
3. How do you assess developer quality?
Run a code review and a 60-minute pairing session. Check Lighthouse scores aiming for 90+, confirm TypeScript, Jest tests, and clean Git history. Include a production sample from e-commerce, healthcare, or fintech.
4. What common front-end bugs should I watch?
Expect async issues and missing Promise error handling. Watch the this keyword, var versus let scope errors, and == versus === coercion. Measure rendering with Lighthouse and fix DOM repaint hotspots to prevent memory leaks.

Staffenza offers full-time, contract, temp-to-hire, and managed teams. Rates range from $20 to $120 per hour depending on seniority and location. Expect 85% retention at 12 months from our vetted network.
