Skills word cloud of Web3 Backend Developer applicants
Skills distribution across applicants highlights hands-on Web3 capabilities (Solidity, smart contracts, Ethereum, Node.js, TypeScript).

From Volume to Precision

Most hiring flows stop at keyword matching. Our AI hiring software evaluates capability—mapping applicants to role-aware checkpoints so only production-ready Web3 engineers make the shortlist.

Key outcome: Shortlists prioritize candidates with verifiable smart-contract delivery and backend services experience—so teams ship faster, safer.

How We Evaluate

Each applicant is scored 0–10 across six checkpoints calibrated for Web3 backend roles:

Smart Contract Development (Solidity) On-chain Integration (Ethers.js/Web3.js) Backend APIs (Node.js/Express/Nest) Data & Persistence (PostgreSQL/MongoDB) Reliability & DevOps (Docker/CI/CD) Security & Testing (Hardhat/coverage)

Checkpoint Score Distribution

This Marimekko-style chart summarizes 259 applicants by checkpoint and score band. Each column is a checkpoint; stacked colors show score brackets (0–2, 3–4, 5–7, 8–9, 10). Taller stacks mean more candidates scored at that checkpoint; more color at the top (8–10) means stronger proficiency.

Columns (left→right): Senior-Level Backend Experience, Smart Contract Development, Web3 Backend Integration, Scalable Web3 Architecture, Blockchain Security Principles, dApp API & Data Management.

What it reveals at a glance:

  • Smart Contracts & Integration trend strong: Large 8–9 bands, with a meaningful top 10 slice—solid delivery depth on-chain and at the interface layer.
  • Architecture is mid→upper band: Most candidates sit 5–9; truly senior (10) architects are scarcer.
  • Security is the thinnest at the top: Lower bands (0–4) are sizeable, with relatively few 8–10 scorers—security remains a hiring gap.
  • API & Data skew mid: Heavy 5–7 with fewer perfect 10s—competent, but fewer experts in data modeling and performance.
  • Backend seniority is polarized: Noticeable presence in both lower and top bands—many developers, fewer seasoned platform engineers.

Top 10 Hands-On Skills

  • Solidity — Core language for authoring secure, production smart contracts.
  • Smart Contracts — Practical design, testing, deployment, and lifecycle management.
  • Ethereum — Target network and tooling ecosystem for most dApps.
  • Node.js — Runtime for APIs, indexers, and blockchain integration services.
  • TypeScript — Type-safe code for reliability and maintainability at scale.
  • Web3.js — Programmatic chain interactions: providers, wallets, events.
  • Express.js — Lightweight framework to expose blockchain logic via APIs.
  • MongoDB — Flexible off-chain storage for unstructured dApp data.
  • PostgreSQL — Structured storage for analytics and transactional workloads.
  • Hardhat — Testing, debugging, and deployment workflows for contracts.

Why It Matters

  • Production over buzzwords: Shortlists center on engineers who can ship secure contracts and stable services.
  • Fewer mis-hires: Role-aware scoring exposes gaps in security, testing, or backend rigor early.
  • Time-to-value: Teams start faster with developers already fluent in the target stack.
byteSpark.ai pairs domain expertise with AI scoring to deliver measurable hiring outcomes for Web3 engineering teams.
