What CTOs Say
Smartbrain.io dropped two senior JavaScript pros into our React/Node stack in 36 hours. They untangled consent-flow bugs and implemented tokenization across our gdpr compliance payment gateway, pushing live without downtime. Velocity jumped 32%, QA issues fell by half, and my internal team finally focused on new features.
Megan Parker
CTO
BrightFund Financial
Our Vue storefront was leaking sensitive payment-meta logs. Smartbrain’s augmented devs hardened encryption and added cookie-less tracking in just a sprint. Page speed stayed intact, GDPR audit passed, and we saved a quarter-million by skipping a full-time hire.
Luis Reynolds
Head of Engineering
ShopAura Inc.
The team integrated HIPAA-friendly Node micro-services with our Stripe gateway, ensuring patient billing followed GDPR consent logic. Onboarding took one day; their Jest test suite cut release regressions 40%. Truly senior JavaScript talent without recruiter hassle.
Dr. Emily Carter
VP Technology
MediPulse Systems
Smartbrain supplied three Next.js specialists who introduced server-side rendering and encrypted session storage. We processed Black-Friday peaks flawlessly, seeing 27% faster checkout and zero data-subject requests missed. Contracts remained month-to-month—perfect flexibility.
Andre Mitchell
Engineering Manager
GlobeTix Software
Our legacy Angular payment widget violated SCA rules. The augmented dev resolved it, refactored to TypeScript, and introduced automated consent logs. Production errors dropped 60%, and auditors signed off first pass.
Rachel Nguyen
Product Owner
FactoryFlow Robotics
Smartbrain’s Node/Kafka expert patched unpredictable payment retries, then added region-based data residency detection. Service interruptions vanished, churn fell 8%, and my DevOps lead finally sleeps.

Industries We Secure
Fintech & Banking
Fintech firms rely on JavaScript for React and Node micro-front-ends that handle real-time ledgers, PSD2 SCA flows, and fraud dashboards. Augmented developers implement gdpr compliance payment gateway logic—tokenizing PAN data, anonymizing logs, and integrating consent widgets—while maintaining sub-100 ms latency.
E-Commerce
High-traffic stores need split-second checkout. Our JavaScript augmentation embeds secure payment scripts, cookie-less analytics, and dynamic consent prompts that keep cart speed high and GDPR fines at bay.
Healthcare Tech
Patient billing touches PHI. Outstaffed JS experts merge HIPAA and gdpr compliance payment gateway rules, encrypting transactions and crafting React portals that respect data minimization and right-to-erasure demands.
Travel & Hospitality
Pooled booking engines face cross-border data issues. Augmented developers add locale-aware payment gateways, implement SCA, and cache anonymized itineraries, preserving seamless UX while passing GDPR audits.
SaaS Platforms
SaaS vendors monetize via in-app purchases. JavaScript teams from Smartbrain embed micro-billing widgets, consent managers, and role-based access—all meeting gdpr compliance payment gateway standards.
Media Streaming
Subscription models require recurring billing. Our Node specialists secure webhooks, add data residency routing, and compress encryption overheads for uninterrupted HD streams with full GDPR alignment.
Manufacturing IoT
Connected devices send purchase telemetry. Outstaffed JS coders build gateway APIs that separate personal and machine data, apply edge encryption, and store tokens in EU regions.
EdTech
Student payments involve minors’ data. JavaScript augmentation crafts age-appropriate consent modals and stores tokenized payment info inside region-locked PostgreSQL clusters.
Logistics
Courier portals process COD and card-on-file details. Our React/Redux pros integrate gdpr compliance payment gateway libraries, ensuring drivers can transact while audit trails remain anonymized.
gdpr compliance payment gateway Case Studies
Stripe Re-Architecture for EU Neo-Bank
Client: Digital-only retail bank
Challenge: Their existing Stripe integration breached GDPR compliance payment gateway rules by storing unencrypted metadata outside the EU.
Solution: A two-person Smartbrain JavaScript squad refactored the Node middleware, introduced JWE encryption, and migrated logs to an EU-hosted PostgreSQL. All changes were delivered through CI/CD within three sprints.
Result: 63% latency reduction on payment endpoints, zero audit findings, and customer churn fell 5%.
One-Click Checkout for Global Retailer
Client: Fortune-100 apparel brand
Challenge: Checkout abandonment spiked after GDPR consent pop-ups clashed with the payment gateway.
Solution: Augmented React/TypeScript devs rebuilt the flow with server-side rendered consent components and integrated tokenization using Braintree APIs.
Result: 18% faster checkout, 22% higher conversion, and compliance sign-off in four weeks.
Usage-Based Billing for SaaS Analytics Vendor
Client: B2B analytics scale-up
Challenge: Introducing usage-based billing required a gdpr compliance payment gateway that could separate corporate and personal data in real time.
Solution: Smartbrain’s Node/Kafka experts built a micro-service that tokenized personal identifiers, streamed anonymized metrics, and triggered Strong Customer Authentication only when needed.
Result: Billing accuracy up by 99.7%, support tickets down 40%, and launch hit market two months early.
