The Problem
When you browse a talent marketplace, you are guessing. You see a resume that claims '5 Years PostgreSQL,' but you don't know:
Can they configure HNSW indexes for production vector search, or do they just use default pgvector settings?
Have they designed partition strategies that handle millions of daily transactions without deadlocks?
Do they understand WAL configuration for high-throughput workloads, or just rely on cloud defaults?
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 PostgreSQL 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 PostgreSQL Developers through our platform.
SAM presents candidates with pgvector implementation scenarios requiring HNSW index configuration, distance metric selection, and hybrid query optimization. You receive a scored report showing their multi-model database expertise.
Senior Data Engineers specializing in PostgreSQL command average salaries around $180,000 annually. Traditional agencies extract 20-35% in placement fees. ConnectDevs operates on a flat $69/mo subscription with zero markup.
Scout searches 800M+ public profiles for precise database architecture and vector optimization signals. This delivers a targeted shortlist in days rather than the weeks typical of manual sourcing.
PostgreSQL with pgvector eliminates the need for separate vector stores, reducing architectural complexity and maintaining referential integrity. A dedicated specialist can design hybrid systems that query vectors alongside relational data in single transactions.
SAM specifically tests for WAL configuration, partition strategy design, deadlock prevention in distributed setups, and asynchronous query execution on federated nodes. Candidates with only single-instance experience score poorly.
Every ConnectDevs engagement provides raw assessment data upfront, including competency scores on HNSW tuning and distance metric trade-offs. Audit the data before you invest interview time to minimize the risk of a costly mis-hire.
