What Technical Leaders Say
“Two days after signing we had a senior JavaScript developer untangling our complex payroll API. Smartbrain.io handled onboarding, NDAs and compliance, so my engineers kept focus on product. Throughput rose 32 % and payroll errors disappeared.”
Emily Carter
CTO
BrightPath Health
Smartbrain’s JS talent integrated with our React stack, automated multi-state tax logic and delivered zero-defect releases. Hiring took 48 h versus the usual 6 weeks, slashing backlog and easing my dev team’s stress.
Michael Reed
VP Engineering
Sunrise Logistics
The augmented engineer rewrote our Node.js payout microservice, cutting processing time by 41 %. Integration was frictionless; Slack stand-ups, GitHub PRs, same timezone overlap. Couldn’t have scaled holiday payroll without them.
Sophia Nguyen
HRIS Manager
Apex FinTech
Our manufacturing plant had dozens of union overtime rules. Smartbrain’s developer coded regression-tested algorithms in TypeScript and Cypress. Deployment hit production in three sprints, boosting compliance reporting accuracy to 99.7 %.
David Brooks
Dev Team Lead
BlueWave Manufacturing
Black-Friday chaos solved. The contractor stabilised our Vue.js payroll dashboard and added real-time retry logic for Stripe payouts. Productivity jumped, and my on-site staff finally slept.
Olivia Peterson
CIO
Horizon Retail
Energy sector compliance is brutal. Smartbrain’s senior Node dev traced ACH failure causes, implemented retries & monitoring in Grafana, and trained my team. Deployment in 10 days, downtime cut to minutes.

Industries We Empower
FinTech & Payroll
FinTech firms rely on real-time salary disbursement, multi-currency wallets and strict SOC-2 audits. Augmented JavaScript developers craft secure ledger micro-services, build reconciliation dashboards, and fortify hr management software payment flows with Node.js, TypeScript and Kafka so funds reach employees without delays or compliance fines.
Healthcare HR Compliance
HIPAA, shift differentials, credential tracking—our JS specialists automate them all. Hospitals use our augmentation to integrate FHIR-compatible payroll modules, ensuring every nurse receives correct premiums while protecting PHI. No full-time hiring, just instant capacity.
Retail & eCommerce
Seasonal surges demand elastic payroll engines. JavaScript contractors optimise React & Node payroll apps, sync POS timesheets, and slash payout latency so thousands of temps get paid accurately during peak sales.
Manufacturing Workforce
Union rules, overtime caps and shift swaps generate complex calculations. Our augmented team embeds formula engines, Cypress tests and CI/CD pipelines to keep factory payroll precise while internal staff focus on MES systems.
Logistics & Transportation
Per-mile pay, detention fees and fuel bonuses create tricky payroll scenarios. JavaScript augmentation lets carriers automate these variables in Express.js services, cutting manual adjustments and driver disputes.
Ed-Tech Institutions
Universities juggling grants and adjunct hours use our JS experts to integrate Banner, PeopleSoft and custom portals, guaranteeing accurate stipend payments governed by multiple funding sources.
Energy & Utilities
Field technicians clock irregular shifts across remote sites. Smartbrain devs create offline-first React Native time apps and Node payroll APIs to keep compensation compliant with union and state law.
Hospitality & Leisure
Tipped wage calculations, split shifts and multi-property pay cycles are solved by our Vue.js specialists, bringing one-click payouts to hotels and resorts without straining HR back-office teams.
Government Contracting
Contractor wage determinations under Davis-Bacon and Service Contract Acts become automated through secure JavaScript modules, ensuring agencies meet audit demands and workers receive correct prevailing wages.
