What technical leaders say
“Smartbrain’s Java pros re-engineered our legacy servlet stack, integrating the Mastercard Payment Gateway Java SDK and cutting settlement errors by 92 %. They blended into our Agile rituals on day 1, letting my core team focus on roadmap features.”
Ethan Carter
CTO
BlueWave Commerce
“We lacked senior back-end capacity for a high-stakes release. Smartbrain delivered two senior Java engineers within 48 h. Their async retry logic and Spring Boot optimisations stabilized our Mastercard payment gateway callbacks, boosting productivity across squads.”
Linda Flores
Head of Engineering
FleetPay Logistics
“Compliance testing used to stall us. Smartbrain’s augmented team automated PCI DSS checks in Java, creating a Jenkins pipeline that shaved 40 hours per release. Onboarding took half a day—impressive.”
Marcus Hill
DevOps Lead
NovaTicketing
“Their low-latency Netty expertise transformed our high-volume kiosk payments. We saw immediate gains and no cultural friction; stand-ups, PR reviews, retros — seamless.”
Rachel Nguyen
VP Technology
CineMaxx USA
“Holiday deadline was looming. Smartbrain staffed three mid-level Java devs plus a QA lead in 72 h. Their rigorous TDD caught 27 critical bugs before prod, protecting revenue.”
George Coleman
Engineering Manager
Giftly Retail
“Our FinTech app needed 3-D Secure 2 FAST. External agencies quoted double. Smartbrain’s outstaff model cut costs 35 % and our PM still directed sprint priorities without vendor lock-in.”

Mastercard Payment Gateway Case Studies
Cross-Border Checkout Acceleration
Client: Global fashion marketplace
Challenge: Seasonal traffic spikes caused Mastercard payment gateway timeouts, jeopardising flash sales.
Solution: Smartbrain deployed four senior Java engineers and one SRE. They refactored synchronous calls into reactive Spring WebFlux services, introduced connection pooling and wrote chaos tests simulating 5× load. A dedicated QA automated gateway regressions.
Result: 38 % latency reduction, 100 % uptime during Black Friday and a 12 % uplift in conversion.
Healthcare Copay Splitter
Client: US tele-medicine provider
Challenge: Needed Mastercard payment gateway integration to split charges between insurance and patient wallets without storing PHI.
Solution: Two augmented Java architects built a tokenisation micro-service, integrated Mastercard Secure Remote Commerce and set up role-based Vault secrets. Compliance artifacts prepared by Smartbrain legal sped up review.
Result: 0 compliance findings, go-live in six weeks, and claims processing time cut by 27 %.
Subscription Revenue Recovery
Client: Streaming startup
Challenge: High churn due to declined renewals on Mastercard payment gateway.
Solution: Augmented Java team added Account Updater, implemented retry orchestration with exponential back-off and built a BI dashboard in Java/Kotlin.
Result: 19 % drop in involuntary churn, MRR up 8 %, ROI achieved in month 2.
