Marketplaces show you profiles. We show you capability.
The Problem
When you browse a talent marketplace, you are guessing. You see a resume that claims '5 Years Ruby,' but you don't know:
Can they explain why Ractors solve the GVL limitation while threads cannot for CPU-bound tasks?
Have they profiled and optimized hot code paths using YJIT and Lazy Basic Block Versioning?
Is their Rails code production-grade or just scaffold-generated conventions without real architecture?
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 Ruby challenges you care about. You don't guess if they are good. You know.

Global Talent Network
Everything you need to know about sourcing, assessing, and hiring top Ruby Developers through our platform.
SAM's technical interview presents candidates with CPU-bound workloads requiring YJIT optimization and Lazy Basic Block Versioning understanding. You receive a scored report showing their ability to leverage Ruby 3.4+ performance features beyond standard Rails patterns.
Senior Ruby developers with YJIT and Ractor expertise command salaries around $168,000 annually. Traditional agencies extract 20-35% placement fees. ConnectDevs operates on a flat subscription with zero markup, significantly reducing total hiring cost.
The Scout agent searches 800M+ public profiles for Ruby ecosystem signals including Rails contributions, gem authorship, and performance optimization portfolios. This delivers a targeted shortlist in days rather than the weeks typical of manual sourcing.
Traditional Ruby threads are constrained by the Global VM Lock, limiting true multicore parallelism. Ractor::Port in Ruby 4 enables actor-style parallelism for CPU-bound tasks. If your workload involves heavy computation, Ractor-experienced developers deliver significant performance gains.
YJIT delivers up to 25% performance improvements for Rails applications and 40% for numeric calculations. Candidates without YJIT understanding leave performance on the table. Scout filters for developers who can profile and optimize hot code paths using modern Ruby JIT features.
Every ConnectDevs engagement provides raw assessment data upfront, including competency scores on YJIT tuning, Ractor implementation, and memory profiling. Audit the recorded technical interview before you invest time to minimize the risk of a costly mis-hire.
