The Problem
When you browse a talent marketplace, you are guessing. You see a resume that claims '5 Years REST API,' but you don't know:
Can they design an idempotency strategy that survives network failures on your payment endpoints without duplicate transactions?
Do they know how to implement a Token Bucket rate limiter in Redis, or have they only read about it?
Have they actually shipped a HATEOAS-compliant API, or do they just know the acronym?
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 REST API 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 REST API Developers through our platform.
SAM presents candidates with payment and mutation endpoint scenarios and asks them to design idempotency key strategies that survive network retries without duplicate transactions. You receive a scored report on their distributed systems reasoning — not a checklist of HTTP verb definitions.
Senior REST API developers with distributed systems experience average around $160,000 annually, with bill rates between $78 and $120 per hour. Traditional agencies charge 20–35% placement markups. ConnectDevs runs on a flat $69/mo subscription with zero placement fees.
Scout searches 800M+ public profiles for signals beyond job titles — including contributions to distributed API infrastructure, rate limiting implementations, and OAuth 2.1 integration patterns. A skill-matched shortlist is ready in days, not weeks of manual search.
When your system handles financial transactions, high-frequency mutations, or multi-tenant SaaS workloads, the cost of a badly designed API multiplies fast. A specialist who can implement the Saga pattern for long-running operations and reason through gRPC versus REST trade-offs prevents architectural debt that generalists typically introduce.
HATEOAS level 3 maturity remains a high-signal marker for senior REST API architects because it decouples client-side logic from API structure — reducing the brittle hardcoding that accumulates in fast-moving product teams. SAM specifically probes for this in senior-level assessments to separate practitioners from candidates who have only read about it.
That is exactly the point. Every SAM report surfaces competency scores, identified risks, and specific challenge results before you invest interview time. You can either adjust role requirements or request a refined shortlist — with full visibility into the data driving each decision.
