What tech leaders say

“Our legacy HR app choked on multi-state tax forms. Smartbrain’s JavaScript duo integrated a new React + Node onboarding paperwork payment engine that auto-calculates deductions. Ramp-up took one day, quality commits started day two, and sprint velocity jumped 28%.
Best part: zero disruption to our roadmap.”

Emily Parker

CTO

BrightPath Logistics

“PCI compliance kept delaying our launch. The contracted Smartbrain engineer refactored our JavaScript payment engine and wired Stripe webhooks into the onboarding paperwork flow. Deployment hit prod in 11 days, saving the quarter.”

Carlos Mitchell

VP Engineering

RetailNova Inc.

“HIPAA forms plus real-time payouts sounded impossible. Smartbrain supplied two senior Vue/NestJS developers who nailed encryption and audit trails. Our clinicians now complete onboarding in 7 minutes—previously 25.”

Grace Lee

Director of Product

WellChain Care

“Payroll errors cost us $40k last year. Smartbrain’s augmented specialist rebuilt the onboarding paperwork payment engine in TypeScript, adding validation layers and unit tests. Error rate is down 93%, finance finally sleeps.”

Michael Johnson

Head of Software

“Hiring fast was critical. Three Smartbrain engineers joined our React Native team, automating contractor onboarding paperwork and instant payments. Feature backlog burned down 2× quicker; investors noticed.”

Sara O’Neil

Co-Founder / CTO

GigSphere Labs

“Regulators demanded transparency. The Smartbrain JavaScript architect implemented event-sourcing in our onboarding paperwork payment engine. Audit queries that took hours now resolve in seconds, and we passed SOC 2 first try.”

Onboarding Paperwork Payment Engine Case Studies

Client: US nationwide freight carrier
Challenge: The legacy onboarding paperwork payment engine could not compute multi-state per-diem rules, delaying driver start dates.

Solution: A two-person augmented JavaScript squad (React, Node, TypeScript) embedded with the client’s scrum team. They refactored tax-rule modules into serverless Lambda functions, built a dynamic form builder, and implemented automated unit tests covering 98% of business logic.

Result: 47% faster driver activation, 0 payroll errors in first quarter, and HR processing cost lowered by 32%.

Client: VC-backed telemedicine platform
Challenge: An outdated onboarding paperwork payment engine could not satisfy HIPAA encryption mandates, threatening launch clearance.

Solution: Smartbrain augmented a senior JavaScript architect and a QA automation engineer. The pair re-engineered REST endpoints to use JOSE JWT encryption, integrated Stripe Connect for payments, and added Cypress e2e tests for every critical path.

Result: 100% compliance sign-off, patient onboarding time cut from 20 to 6 minutes, and support tickets down by 65%.

Client: Global eCommerce marketplace
Challenge: Legacy PHP onboarding paperwork payment engine failed under holiday surge, causing lost sellers.

Solution: Three Smartbrain JavaScript engineers built a micro-frontend React workflow fed by GraphQL APIs, added asynchronous payment reconciliation in Node, and used AWS Step Functions to orchestrate verification steps.

Result: Onboarding throughput increased by 4×; seller drop-off fell from 28% to 7%; deployment frequency improved to daily.
