The Problem
When you browse a talent marketplace, you are guessing. You see a resume that claims '5 Years Back End,' but you don't know:
Is their experience limited to monolithic CRUD apps without distributed systems exposure?
Do they understand the CAP theorem when managing race conditions at scale?
Can they securely manage JWT lifecycles across decoupled microservice boundaries?
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 Back End challenges you care about. You don't guess if they are good. You know.

Global Talent Network
Most teams hiring backend engineers also need runtime environments, database layers, and asynchronous messaging infrastructure.
Everything you need to know about sourcing, assessing, and hiring top Back End Developers through our platform.
Resumes often falsely conflate building simple APIs with managing complex distributed architectures. SAM conducts structured evaluations on advanced topics like circuit breaker patterns and handling network partitions. You receive decision-ready insights verifying their capability to build fault-tolerant systems.
Traditional recruitment firms extract massive premiums, often charging 20% to 35% of a senior developer's $180,000+ salary as a placement fee. By transitioning to a transparent $69/mo flat subscription, organizations realize zero markup. This model dramatically reduces your cost-per-hire.
Manual technical screening is the primary bottleneck for engineering managers. The Scout agent instantly searches 800M+ public profiles to build a highly qualified initial pool. This intelligence engine delivers a shortlist ready in days, not weeks, allowing your CTO to focus on final decisions.
While microservices offer scaling advantages, they introduce massive complexity regarding service discovery and eventual consistency. Teams should only migrate if they have verified talent capable of managing event-driven architectures. We specifically source candidates assessed on these exact transitional challenges.
Insecure APIs are the leading vector for data breaches. We ensure candidates are rigorously tested on implementing robust OAuth flows and mitigating OWASP vulnerabilities. Our assessment-backed profiles provide concrete data regarding a developer's adherence to security best practices.
You set the exact architectural criteria required for your stack, whether that involves GraphQL, gRPC, or specific message brokers. We provide the tailored intelligence and structure, ensuring the candidates presented match your specific operational realities.
