What technical leaders say about marketing attribution payment engine talent
Smartbrain.io delivered two senior JS devs within 4 days. They rewired our React + Node marketing attribution payment engine, eliminating duplicate pixel fires and syncing spend to Stripe. Velocity jumped 30 % and my analysts finally trust the numbers.
Alicia Carter
CTO
BluePeak Media
Their augmented squad integrated seamlessly with our Vue front-end and AWS Lambdas. Smartbrain’s vetting meant zero ramp-up; feature lead-time fell by 40 %, letting us launch cohort-based ROAS dashboards ahead of Q4.
Victor Nguyen
VP Engineering
FleetFintech Inc.
We struggled matching PayPal webhooks to ad clicks. Smartbrain’s Node experts built an event-driven service that reconciles in real time. Support tickets dropped 60 %—and my team can focus on feature work again.
Emma Johnson
Technical Director
Sportify Gear Co.
Smartbrain.io embedded a senior TypeScript engineer who optimised our Kafka streams and React dashboards. Monthly reconciliation that took 8 hours now completes in 20 minutes. ROI speaks for itself.
Michael Reed
Head of Data
CivicBank Digital
From contract to code merge was 72 hours. Their developer refactored our Next.js funnels and introduced automated Jest suites—quality rose and we hit Black-Friday traffic without a hiccup.
Olivia Martinez
Engineering Manager
EcoBeauty Labs
Needed experts in serverless attribution billing. Smartbrain delivered. Lambda cold starts down 35 %, reporting latency -50 %. Couldn’t hire locally this fast or this good.

Industries we empower with JavaScript attribution expertise
eCommerce & DTC
Challenge: Tracking ad clicks through multi-channel carts to final payment.
Our JavaScript attribution developers build event-stream data layers, deduplicate sessions, and reconcile Shopify/Stripe transactions, giving DTC brands precise ROAS and LTV metrics.
FinTech Platforms
Complex payment routing demands marketing attribution payment engine accuracy. We craft Node micro-services that tag every ledger entry with its campaign source, enabling granular CPA analysis for regulated FinTech operators.
SaaS Subscription
Our augmented JS teams connect React front-ends with usage-based billing APIs, correlating in-app events to PPC spend so SaaS CFOs finally see true CAC vs ARR.
AdTech Vendors
We reinforce RTB pipelines with TypeScript, Kafka and Redis, ensuring milli-second attribution stamps survive auction hops and appear in revenue dashboards in real time.
HealthTech
HIPAA-safe attribution requires client-side hashing and server-side de-identification. Our specialists implement secure JavaScript SDKs that map marketing to patient acquisition without PHI leakage.
Travel & Hospitality
Multi-touch journeys span web, mobile and kiosks. We instrument React-Native apps and legacy Angular portals, tying bookings to ads for dynamic budget re-allocation.
Gaming & Esports
High-frequency events overwhelm basic analytics. Our JS devs stream gamer telemetry through WebSockets, linking wins to promo codes for precise campaign ROI.
EdTech
We connect LMS engagement metrics to marketing sources via serverless Node collectors, letting product teams double-down on profitable acquisition channels.
PropTech
Long sales cycles obscure attribution. Our engineers stitch CRM milestones to JavaScript tracking pixels, surfacing which ads drive closed deals in real estate platforms.
