What Technical Leaders Say
4 JavaScript contractors onboarded in 6 days—all masters of Node.js, TypeScript, and browser fingerprint libraries. They refactored our risk-scoring micro-service and cut false positives by 18%. Ramp-up was painless; Smartbrain handled contracts, NDAs, and payroll so my engineers kept shipping.
Brandon Kelly
CTO
FinShield Analytics
Our React storefront faced bot checkout abuse. Smartbrain’s augmented dev joined in 5 business days, integrated FingerprintJS, and tuned Webpack for sub-second loads. Chargebacks dropped 27% in the first month, saving both money and customer trust.
Samantha Pierce
Head of Engineering
ShopRelay Inc.
Smartbrain delivered two senior Vue.js/Node.js specialists who rewrote our anti-fraud SDK in ES6. Integration with our GraphQL API was seamless; productivity jumped 22% and onboarding took mere days. The service freed my core team to focus on gameplay features.
Diego Ramirez
VP Engineering
PlayVerse Studios
HIPAA compliance made hiring tough. Smartbrain supplied vetted JavaScript pros seasoned in secure coding. Within a week they added fingerprint entropy checks written in React Native, blocking credential stuffing without impacting UX. Audit readiness improved instantly.
Elaine Foster
Product Security Lead
WellTrack Systems
We needed SSR-friendly device fingerprint fraud detection for our Next.js bidding engine. Smartbrain sourced a senior dev in 48 hours who optimized TypeScript modules and reduced bots by 35%. The contract’s month-to-month flexibility fit our volatile roadmap.
Marcus Lee
Engineering Manager
AdQuantum Media
Three Node.js micro-frontend experts from Smartbrain migrated our legacy fraud scripts to modern ES2022, adding WebRTC fingerprint signals. Onboarding was fully guided, SLAs clear, and productivity metrics rose 25%. Couldn’t ask for smoother collaboration.

Where Our JavaScript Fingerprint Experts Excel
FinTech & Banking
Fraud-heavy transactions demand bulletproof identification. Augmented JavaScript developers build encrypted browser fingerprint collectors, integrate with AML engines, and craft real-time dashboards in React to flag suspicious ACH or card activity. Their device fingerprint fraud detection scripts correlate cookies, WebGL, and canvas entropy, reducing account takeover risk while meeting PCI-DSS standards.
E-commerce & Retail
Checkout abuse, promo stacking, and bot scalping cripple margins. Outstaffed JS experts embed FingerprintJS Pro, use Node.js queues for rate limiting, and create Vue anti-fraud widgets that validate every device in <50 ms. The solution slashes chargebacks and keeps UX friction-free.
AdTech & MarTech
Impression fraud wastes budgets. JavaScript augmentation teams implement device fingerprint fraud detection inside programmatic bidding scripts, pairing canvas hashing with IP reputation to filter ghost clicks. React dashboards visualize spend leakage in real time.
iGaming & Betting
Multiple-account creation undermines fair play. JS specialists craft Node.js services that fingerprint browsers, cross-check geolocation, and block VPN obfuscation—protecting odds engines without violating GDPR.
Ride-Sharing & Mobility
Driver/passenger fraud erodes trust. Augmented developers integrate device fingerprint SDKs with real-time Firebase streams, alerting ops when SIM swaps or rooted devices appear, keeping trips authentic.
Healthcare Portals
PHI security mandates strict identity controls. React Native teams fingerprint devices accessing tele-health screens, meeting HIPAA while thwarting credential stuffing and bot scraping of lab results.
Media Streaming
Password sharing and region spoofing hit revenue. JavaScript pros build fingerprint-based entitlement checks inside ReactTV apps, dynamically disabling streams on cloned devices.
SaaS Security Tools
B2B platforms need granular visibility. Outstaffed JS engineers craft embeddable fraud widgets, leverage TypeScript, and expose GraphQL APIs so clients can query fingerprint risk scores directly.
Telecom & ISP
SIM swap and subscription fraud spike churn. Node.js micro-services ingest browser fingerprints alongside network telemetry, surfacing anomalies before revenue leakage occurs.
Device Fingerprint Fraud Detection Case Studies
FinBank Mobile – Fraud Shield Upgrade
Client: Tier-1 mobile banking provider.
Challenge: Device fingerprint fraud detection had to run inside a React Native app without increasing launch time.
Solution: Two Smartbrain JavaScript consultants integrated a lightweight FingerprintJS wrapper, moved entropy calculations to a Web Worker, and added a Node.js Lambda for risk scoring. Code merged in ten days, keeping CI/CD green.
Result: Launch latency dropped by 18 %, while unauthorized session attempts fell 41 % during the first quarter.
ShopCart – Bot Checkout Prevention
Client: Global e-commerce marketplace.
Challenge: Flash-sale bots bypassed CAPTCHAs; stronger device fingerprint fraud detection was urgently needed.
Solution: An augmented trio of Vue.js/TypeScript engineers embedded WebGL fingerprinting and SignalR real-time validation, scaling with Kubernetes.
Result: Bot purchases decreased by 72 % and page render time stayed under 2 s, preserving conversion rates.
StreamWave – Credential Sharing Clampdown
Client: Subscription-based video streaming platform.
Challenge: Multiple households used one login, bypassing limits; needed device fingerprint fraud detection across ReactTV, Web, and iOS.
Solution: Four Smartbrain Node.js specialists built a universal fingerprint API and integrated it across platforms via GraphQL. A rules engine flagged abnormal device clusters.
Result: Unauthorized streams fell by 53 %, adding $3.2 M ARR without extra infrastructure cost.

Services We Provide
SDK Integration
Our outstaffed engineers plug leading device fingerprint fraud detection SDKs—FingerprintJS, ThreatMetrix—into your React, Vue, or Angular stack, exposing concise TypeScript interfaces so your team ships features instead of wrestling with vendor docs.
Custom JS Fingerprint Engine
Need full control? Augmented seniors craft a proprietary fingerprint collector in ES2022, capturing canvas, audio, WebGL, and sensor entropy. You own the IP; we deliver the code.
Real-Time Risk Scoring
Node.js micro-services stream device signals to Redis and Kafka, scoring threats under 100 ms. Our developers tune clusters, ensuring horizontal scalability for global traffic peaks.
Dashboard & Analytics
React/Next.js experts design executive dashboards that visualize fingerprint risk, false-positive trends, and A/B experiments—giving stakeholders clear ROI insights.
Performance Optimization
Outstaffed JavaScript gurus shave kilobytes and milliseconds, splitting bundles, enabling HTTP/3, and offloading heavy fingerprint math to Web Workers—keeps Core Web Vitals green.
Compliance & Data Privacy
Our team aligns fingerprint collection with GDPR, CCPA, and PCI, implementing consent banners, anonymization layers, and audit logs so legal teams sleep easy.
