Why outstaff instead of direct hiring?
Finding senior engineers who truly master JavaScript-based, API-first payment orchestration can drain months and budgets. Outstaffing through Smartbrain lets you tap a ready bench of pre-vetted specialists instantly, without payroll, recruitment fees, or long-term liabilities. You scale teams up or down on-demand, stay focused on core product, and keep full IP ownership. Our developers join daily stand-ups as if in-house, yet all admin, HR, and compliance stay on us—cutting total cost up to 40 % while keeping delivery velocity high.

What CTOs Say About Our api-first payment orchestration Teams
“Smartbrain dropped two Node.js wizards into our fintech squad in 5 days. They built a dynamic routing layer that slashed failed transactions by 23 %. The contractors felt like full-timers—same stand-ups, same code reviews—allowing my team to focus on React checkout flows and hit deadline.”
Melissa Harper
CTO
VeloPay Inc.
“Our legacy Java platform needed a JavaScript micro-service to orchestrate multi-acquirer routing. Smartbrain’s dev integrated TypeScript, AWS Lambda and Stripe APIs in record time. Time-to-first-commit: 48 hrs; performance improved 19 %.”
David Lin
Head of Engineering
BlueWave Logistics
“Smartbrain supplied a senior Vue.js engineer who refactored our cart and plugged in a unified payment API. Bounce rate dropped 11 % and cash-flow forecasting became real-time. Hiring in-house would have taken months.”
April Gomez
Digital Product Lead
StyleHub Stores
“We’re a B2B SaaS issuing invoices to 50 countries. Smartbrain’s React & Node duo built tokenized card vault services that passed PCI-DSS audit first try. QA defects fell 37 %. Couldn’t ask for smoother onboarding.”
Gregory Brooks
VP of Technology
InvoiceRocket LLC
“HIPAA compliance scared most vendors. Smartbrain matched us with senior JavaScript devs experienced in secure GraphQL gateways. They delivered an acquirer fail-over module, keeping uptime at 99.995 %.”
Karen Mitchell
Chief Product Officer
MediBridge Systems
“Flash sale peaks killed our monolith. Smartbrain’s augmentation team containerised a payment micro-service in Kubernetes and introduced dynamic routing logic. Throughput up 2.3×, and we kept the contracts monthly.”

Industries We Empower
Fintech & Banking
Fintech platforms rely on JavaScript-driven, api-first payment orchestration to route transactions across multiple PSPs, tokenise cards, and comply with PCI-DSS. Augmented devs integrate Stripe, Adyen, Braintree, build fraud-screening micro-services, and optimise latency for instant authorisations—all while product teams stay focused on feature road-maps.
eCommerce Marketplaces
Multi-vendor marketplaces need split-payments, escrow, and dynamic fee calculation. Outstaffed JavaScript experts craft serverless Node.js functions that harmonise PayPal, Klarna, and local gateways, ensuring buyers pay seamlessly in any currency and sellers get real-time settlement.
SaaS Subscriptions
SaaS companies juggle recurring billing, usage metering, and prorations. Our augmented developers plug in Chargebee or build custom billing engines, expose REST/GraphQL endpoints, and enable churn-reducing retry logic through smart orchestration layers.
Digital Media
Streaming and news outlets monetize content through paywalls and micropayments. JavaScript specialists implement tokenised wallets, low-latency checkout, and optimise CDN interactions, keeping conversion high at global scale.
Travel & Mobility
Ride-sharing, airlines, hotels process cross-border cards and alternative payments. Augmented teams build routing logic that selects the cheapest acquirer per region and adds PSD2 SCA flows without hurting UX.
Healthcare
Tele-health platforms demand HIPAA and PCI compliance. JavaScript devs from Smartbrain craft secure payment APIs, encrypt PHI, and integrate insurance co-pays into a single orchestration layer.
EdTech
Online learning portals need flexible pricing—one-off, bundles, subscriptions. Our specialists weave Stripe Checkout and custom discount engines together, exposing a unified payment SDK for course creators.
Gaming
Gaming studios deal with micro-transactions and loot-boxes. Outstaffed Node.js engineers create high-throughput payment micro-services, integrate fraud analytics, and localise dozens of alternative payment methods.
Non-profit & Donations
Fund-raising platforms must minimise fees and maximise trust. Smartbrain’s JavaScript experts implement multi-currency donation flows, instant tax-receipt generation, and real-time funding dashboards through an orchestrated API layer.
api-first payment orchestration Case Studies
Scaling Checkout for a SaaS Leader
Client: B2B SaaS platform serving 70 K businesses.
Challenge: Cart abandonment surged because of sluggish api-first payment orchestration built on a single gateway.
Solution: Two augmented JavaScript engineers created a micro-service that dynamically routes payments to three PSPs and adds WebSocket status callbacks. They collaborated daily via Slack, shipped Terraform IaC, and handed over full test coverage.
Result: 22 % latency reduction, 9 % higher conversion, and zero downtime during migration.
Real-Time Settlement in Fintech
Client: VC-backed fintech issuing multi-currency cards.
Challenge: Settlement delays due to fragmented api-first payment orchestration workflows.
Solution: Smartbrain provided three senior Node.js/TypeScript devs who refactored the orchestration layer into event-driven Kafka streams and introduced tokenised card vaults. CI/CD pushed to AWS Fargate within two weeks.
Result: 95 % of settlements occur in under 5 minutes, support tickets fell by 37 %.
Marketplace Cross-Border Expansion
Client: Global P2P marketplace.
Challenge: Entering LATAM required compliant api-first payment orchestration with local PSPs.
Solution: A blended team of Smartbrain React and Node.js contractors built a modular adapter layer, added currency conversion micro-service, and enabled PSD2 SCA. All delivered in eight sprints.
Result: 3× growth in new-region GMV and 0 % chargeback increase.
