Why augment, not hire?
Direct recruitment of JavaScript engineers specialised in loss prevention subscription is slow, costly and risky. With Smartbrain.io outstaffing you plug pre-vetted talent into your stack within days—no head-hunter fees, no long-term payroll obligations. Our engineers remain on our books, so you avoid HR, tax and compliance overhead while still steering daily work as if they were employees. Scale teams up or down instantly in response to churn-spike investigations or seasonal subscriber peaks. You keep 100% IP ownership; we handle hardware, benefits and continuous up-skilling—saving you budget and management bandwidth.

What Tech Leaders Say About Our Loss Prevention Subscription Talent
“Smartbrain’s JS squad curtailed chargeback losses by 37% in six weeks.” Their React-Node duo plugged into our micro-services in a day, automated fraud rule updates and gave our analysts a real-time dashboard. Productivity jumped, backlog shrank, and our own devs could focus on new revenue features.
Megan Pierce
VP Engineering
CrescentPay Inc.
Integration was seamless. Two JavaScript pros from Smartbrain rewrote our legacy billing hooks in TypeScript, eliminating silent payment failures. The team’s unit-test rig improved code coverage to 93%, giving us night-and-day reliability.
Carlos Nguyen
CTO
ShelfSense Systems
Our OTT platform bled subscribers due to token expiry bugs. Smartbrain’s Vue/Nuxt developer fixed it, added churn-prediction scripts and delivered KPI dashboards — all within the first sprint. Onboarding took 48 hours, zero friction.
Lisa Hart
Head of Product
StreamNova Media
Smartbrain gave us a senior Node.js engineer versed in actuarial data. He built a rules engine that flags risky policy renewals, cutting involuntary cancellations by 22%. The monthly contract lets me extend or pause anytime.
Dwight Ellison
Director of Engineering
PolicyPilot Corp.
We lacked bandwidth to battle credential stuffing. Smartbrain’s JavaScript specialist integrated AWS WAF and wrote SSR-friendly CAPTCHA logic in Next.js. Incidents dropped, and my team stayed focused on curriculum features.
Sarah Bell
Engineering Manager
LearnSphere LLC
The augmentation model shaved weeks off hiring. Their Express/React dev audited our Stripe flows, implemented webhook retries, and reduced refund tickets by 31%. Quality documentation made knowledge transfer painless.

Loss Prevention Subscription Case Studies
Chargeback Shield for FinTech App
Client: VC-backed digital wallet.
Challenge: Rising chargebacks threatened margins; loss prevention subscription logic was missing.
Solution: Smartbrain supplied two senior JavaScript developers who rebuilt the transaction screening layer in TypeScript and added ML-driven risk APIs. Integration completed in two sprints; our PM led them remotely.
Result: 37% drop in chargebacks, ROI reached within one month.
Streaming Retention Analytics
Client: Mid-size OTT service.
Challenge: Subscriber churn spiked; missing insights hindered loss prevention subscription decisions.
Solution: We embedded a React-Node duo who delivered cohort dashboards and a predictive churn model, all while pairing with in-house QA.
Result: Churn reduced by 18%; time-to-insight fell from weeks to hours.
Retail SaaS Billing Integrity
Client: Cloud POS vendor.
Challenge: Revenue leakage from silent Stripe failures hurting loss prevention subscription KPIs.
Solution: One senior Node.js engineer implemented idempotent webhook retries and alerting; another optimised React admin UI for anomaly triage.
Result: Billing success rate climbed to 99.3%, saving $1.2 M ARR.
