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 Back-End,' but you don't know:
Can they design gRPC contracts that handle backward compatibility, or do they just copy REST patterns?
Have they implemented the Saga pattern for distributed transactions, or do they rely on fragile two-phase commits?
Is their micro-services architecture production-hardened or a mess of circular dependencies?
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
Teams hiring back-end engineers typically need expertise across the full server-side stack, from databases to orchestration.
RELATED STACK
Everything you need to know about sourcing, assessing, and hiring top Back-End Engineers through our platform.
SAM's technical interview requires candidates to define Protobuf contracts, explain streaming patterns, and compare latency characteristics against REST. You receive a scored report showing their depth of binary protocol expertise.
Senior back-end engineers command average salaries around $195,000 annually. Marketplaces typically extract 15-20% in platform fees. ConnectDevs operates on a flat subscription starting at $69/mo with zero markup on candidate compensation.
The Scout agent searches 800M+ public profiles for signals like Kafka contributions, Go performance work, and micro-services architecture patterns. This delivers a targeted shortlist in days rather than the weeks typical of manual sourcing.
Node.js excels at I/O-bound real-time applications with its event loop. Go provides superior performance for CPU-bound workloads and simpler concurrency primitives. The choice depends on your latency requirements and team familiarity. SAM evaluates candidates on both runtime characteristics.
SAM presents scenarios involving multi-service transactions and asks candidates to design compensation logic, handle partial failures, and explain eventual consistency trade-offs. The evaluation report scores their distributed systems maturity.
Every ConnectDevs engagement provides raw assessment data upfront, including competency scores on load handling and performance optimization. Audit the technical depth before you invest interview time to minimize the risk of hiring someone who only knows low-traffic systems.
