What CTOs Say
“Node.js micro-services were stalling our launch. Smartbrain.io placed two senior engineers in 72 hours. They automated settlement batches, integrated Stripe Webhooks and raised unit-test coverage from 52 % to 93 %. Our Java team could finally focus on core logic while the JavaScript contractors kept payments humming.”
Laura Martinez
CTO
BlueWave Fitness Inc.
“I feared remote talent would slow us down. Instead, the Smartbrain.io dev joined our Slack the next morning, shipped a React subscription dashboard in a week and cut support tickets by 38 %. Accelerated hiring timeline saved the quarter.”
Ethan Price
VP Engineering
OptiMed Devices
“Their TypeScript guru refactored our payment lifecycle queue, introduced Kafka retries and automated PCI evidence collection. Throughput jumped 27 %; audit passed first try. Onboarding took one day—unheard-of in fintech.”
Sophia Turner
Head of Platform
Crescent Capital Markets
“Smartbrain.io’s Vue.js specialist linked Chargebee, QuickBooks and our custom ledger. Reconciliation that took hours is now automatic. Productivity rose 22 % and finance stopped chasing engineering every sprint.”
Michael Reed
Director of Engineering

“We were under a hiring freeze. Smartbrain.io augmented us with a senior full-stack JavaScript dev who wrapped our COBOL billing logic with an Express API and automated nightly settlements. Delivered ahead of schedule, zero HR overhead.”
Olivia Brooks
IT Manager
MidWest Energy Co.
“Three Smartbrain.io engineers tackled 2 M transactions/day, tuning our NestJS services and deploying serverless lambdas for retries. Mean processing latency dropped 41 %. Integration felt like internal staff—same stand-ups, same code review culture.”

FinTech & Banking
FinTech firms rely on JavaScript-driven product lifecycle payment automation to orchestrate ACH, card and crypto flows. Augmented developers add 3-D Secure, dynamic risk rules and ledger reconciliation while meeting PSD2 & PCI. Smartbrain.io staff seamlessly extend teams, ensuring real-time dashboards, React admin portals and Node.js settlement micro-services ship on schedule.
eCommerce Platforms
High-volume carts demand JavaScript payment automation that updates inventory, splits payouts and sends tax data instantly. Our outstaffed engineers integrate Stripe, PayPal and Klarna, optimizing checkout and subscription renewals so retailers capture every sale without hiring delays.
SaaS Subscription
SaaS vendors grow MRR when lifecycle billing—trials, upgrades, churn detection—runs automatically. Smartbrain.io devs embed Chargebee or custom Node services, introducing event-driven billing logic while product teams iterate features.
Healthcare Tech
HIPAA-compliant payment flows for tele-health and medical devices require secure tokenization and audit trails. Augmented JavaScript specialists implement FHIR-ready APIs, automate co-pay collection and integrate clearinghouses, accelerating reimbursement cycles.

Real-time freight and ride-hailing apps depend on automated multi-party payouts. Our experts build Node.js payment aggregators, mileage-based invoicing and driver wallet services that reconcile thousands of trips nightly.
EdTech
Course marketplaces need flexible recurring billing and regional tax handling. Augmented JavaScript teams add metered usage tracking, coupon engines and payment gateway localization, letting educators focus on content.
Media & Streaming
Streaming services monetize via pay-per-view and subscription combos. Smartbrain.io engineers integrate DRM-aware payment automation, auto-upgrade tiers and manage diverse gateways across 190 countries.
Travel & Hospitality
Booking engines juggle deposits, cancellations and multi-currency settlements. Outstaffed JavaScript developers craft micro-services that sync with GDS systems, ensuring automatic refunds and chargeback mitigation.
Manufacturing IoT
Industrial OEMs move to usage-based billing for connected devices. Our specialists design event pipelines and automate invoices from sensor data, bringing product lifecycle payment automation to factory floors.
Product Lifecycle Payment Automation Case Studies
Chargeflow Revamp for FinTech Scale-Up
Client: Series-B digital bank targeting Gen-Z savers.
Challenge: Their Node.js stack struggled with product lifecycle payment automation beyond 500 K users.
Solution: Two Smartbrain.io engineers rewrote cron-based billing into event-driven Kafka streams and introduced TypeScript guards. They paired with in-house devs via mob-programming and delivered PCI evidence packs.
Result: 54 % latency reduction on nightly reconciliation, 0 failed settlements in first 60 days.
Marketplace Multi-Party Payout Acceleration
Client: US mid-market trucking marketplace.
Challenge: Manual carrier payouts delayed cash-flow, breaking product lifecycle payment automation promises.
Solution: A trio of augmented JavaScript devs implemented Stripe Connect, built React finance dashboards and automated disputes workflow. Integration finished in 3 sprints.
Result: Payout cycle cut from 10 days to 48 hours, support tickets down 31 %.
Legacy ERP Billing Modernization
Client: Fortune-100 manufacturer shifting to subscription machinery.
Challenge: COBOL-based invoices prevented real-time product lifecycle payment automation.
Solution: Four Smartbrain.io engineers wrapped legacy services with Express APIs, moved pricing logic to NestJS micro-services and introduced usage metering via MQTT.
Result: Revenue recognition time dropped by 37 %; new plan creation fell from 4 weeks to 3 days.
