Why augment instead of hire?

Direct recruitment for senior-level Java engineers with deep FIS Payments Integration knowledge can eat up 12-16 weeks and burn budget on sourcing, interviewing, payroll and retention. Outstaffing through Smartbrain.io delivers battle-tested Java specialists in 48-72 hours while we shoulder vetting, compliance, HR and local taxation. You pay a transparent daily rate, scale squads up or down on demand and stop whenever the integration reaches production stability—no severance, no idle bench costs.

Result: fewer HR headaches, faster go-live, and predictable costs that map to sprint velocity rather than head-count liabilities.

What tech leaders say

“Smartbrain’s Java squad plugged into our Spring Boot micro-services overnight. Within a week the team untangled FIS Payments Integration webhook issues that had stalled us for months, boosting release cadence and letting my architects focus on new features.”

Laura Jenkins

CTO

BrightWave Commerce

“Their pre-vetted Java engineers understood ISO20022 and FIS tokenization day one. Ramp-up took 48 hours and we shipped PCI-DSS compliant code two sprints earlier than plan—huge win for our investors and clients.”

Anthony Reed

VP Engineering

OrbitPay Solutions

“Smartbrain delivered low-latency Java expertise we lacked. Their devs refactored our Netty event loop around the FIS socket API, cutting tx latency 37 %. Contract flexibility let us downsize once SLA targets were hit.”

Megan O’Neill

Platform Engineering Lead

FirstHarbor Bank

“The augmentation model saved months of hiring. Two senior Java consultants integrated FIS batch payouts into our legacy JEE stack, reducing manual reconciliation and freeing underwriting teams to focus on customers.”

Richard Gomez

Director of Technology

SafeSure Insurance

“From Kafka event streaming to Spring Cloud, their Java pros nailed it. Checkout failures dropped 42 % and Black Friday handled 3× traffic without a glitch—can’t imagine doing it without Smartbrain.”

Emily Carter

Engineering Manager

UrbanThreads Retail

“We closed our Series B partly thanks to the velocity Smartbrain unlocked.” Four augmented Java engineers delivered a high-throughput FIS Payments Integration microservice, moving KPI release dates up by a quarter.

FIS Payments Integration Case Studies

Global Bank – Same-day Settlement

Client: Tier-1 international retail bank.

Challenge: Legacy core could not handle growing mobile traffic while maintaining FIS Payments Integration batch windows.

Solution: A four-person augmented Java squad rewrote settlement modules into reactive Spring WebFlux services, introduced Kafka event sourcing, and containerised the flow on OpenShift.

Result: 55 % throughput increase, settlement cut-off moved from 23:00 to 21:00, and ops incidents dropped by 70 % within three months.

eCommerce Unicorn – Black-Friday Readiness

Client: NASDAQ-listed marketplace.

Challenge: FIS Payments Integration latency spiked during flash-sale peaks, risking cart abandonment.

Solution: Two senior Smartbrain.io Java engineers optimised Netty NIO pipelines, added Redis connection pooling, and implemented circuit-breaker patterns around FIS endpoints.

Result: Peak checkout latency dropped by 37 %; revenue on Black Friday grew 22 % YoY without extra infrastructure cost.

Insurtech Scale-up – PCI Modernisation

Client: Series-C insurtech with 6 M policies.

Challenge: Achieving PCI-DSS Level 1 while adding FIS Payments Integration to legacy Java EE stack.

Solution: Augmented team built micro-gateway with Quarkus, implemented tokenisation, and automated compliance scans in CI/CD.

Result: Passed audit in 9 weeks, card breach risk reduced by 98 %, and customer onboarding time fell from 7 to 2 minutes.

Our Java Outstaffing Services

Gateway Integration

End-to-end implementation of FIS payment gateways using Java Spring APIs, including tokenisation, fraud-rule orchestration and automated reconciliation. Our augmented developers ensure PCI-DSS compliance and zero-downtime deployment, accelerating go-live by up to 50 % versus in-house builds.

Legacy Modernisation

Refactor monolithic JEE or COBOL payment modules into micro-services, introduce Kafka event streams and containerise on Kubernetes—all without pausing business. Outstaffed Java experts deliver incremental FIS Payments Integration upgrades that cut maintenance cost and tech-debt.

Performance Tuning

Low-latency tuning of FIS socket APIs, Netty optimisation, JVM profiling and cache strategy design. Achieve sub-100 ms transaction times and support Black-Friday-level spikes confidently.

Compliance Automation

Build Java-based audit trails, encryption vaults, and CI/CD security gates that keep FIS integrations aligned with PCI, PSD2 and ISO27001—reducing audit prep time by 70 %.

24/7 Production Support

Augmented DevOps engineers monitor Java payment services, provide SRE dashboards and incident response. Mean-time-to-recover slashed while your core team sleeps.

Feature Extensions

Add new payment methods, multi-currency wallets or loyalty modules on top of existing FIS Payments Integration. Our Java specialists deliver business value without disrupting the roadmap.
