The Problem
When you browse a talent marketplace, you are guessing. You see a resume that claims '5 Years Front-End,' but you don't know:
Can they optimize Largest Contentful Paint and Cumulative Layout Shift, or do they just write functional components?
Have they architected state management for data-heavy applications using Signals or Observables, or do they rely on basic useState?
Do they understand isomorphic JavaScript and edge rendering, or only client-side single-page apps?
The Solution
ConnectDevs removes the guesswork. We don't just send profiles; we send Structured Intelligence. Every candidate is interviewed by SAM against the specific Front-End challenges you care about. You don't guess if they are good. You know.

RELATED STACK
Everything you need to know about sourcing, assessing, and hiring top Front-End Developers through our platform.
SAM evaluates candidates on practical optimization scenarios including code-splitting, lazy loading, and edge computing for distributed rendering. You receive a scored report showing their ability to achieve target LCP and CLS metrics on real-world applications.
Senior front-end developers command average salaries around $180,000 annually across the United States. Traditional agencies add 20-35% in placement fees. ConnectDevs operates on a flat $69/mo subscription with zero markup.
Scout searches 800M+ public profiles for modern JavaScript signals including React, TypeScript, and performance optimization experience. This delivers a match-scored shortlist faster than manual sourcing, typically ready within days.
Front-end specialists bring deep expertise in rendering strategies, state management patterns, and performance optimization that generalists lack. If your product depends on fast load times, complex UIs, or mobile-first design, a specialist delivers measurably better user experience.
TypeScript adoption has become standard for large codebases, providing type safety that prevents runtime errors and improves maintainability. Developers with only JavaScript experience face a learning curve on generic types, advanced inference, and tooling integration.
Every candidate includes structured assessment data with competency scores on rendering optimization, state management, and cross-browser compatibility. Review recorded technical interviews and code samples before committing interview resources to reduce mis-hire risk.
