Where our Java talent delivers value

Retail Banking & Fintech

Retail banks race to digitize core ledgers while complying with Japan’s FSA guidelines. Augmented Java teams re-engineer FIS COBOL modules into Spring Boot micro-services, implement open-banking APIs, and enable real-time settlements—reducing batch windows and unlocking new fintech partnerships.

Insurance Platforms

Policy administration systems on FIS rely on heavy mainframes. Java augmentation injects domain experts who migrate rating engines to cloud-native Java 17, integrate actuarial data with Kafka, and deliver faster quote & bind cycles.

Capital Markets

Trading desks demand millisecond latency. Outstaffed JVM developers optimize FIX gateways, build reactive streams over Netty, and modernize FIS Core Banking Modernization modules to support T+0 settlement.

Payments & Remittance

ISO 20022 and BOJ-Net mandates push payment firms to modernize. Java specialists craft message translators, real-time fraud engines, and FIS Profile extensions that scale to thousands of TPS.

E-commerce Lending

Buy-Now-Pay-Later providers tap augmented Java squads to create credit-decision micro-services, integrate FIS ledger data, and meet PCI-DSS without hiring full teams internally.

Healthcare Finance

Hospitals managing patient financing need HIPAA-compliant modernization. Java devs re-write billing modules, secure data with Spring Security, and expose FHIR APIs connected to FIS back-office.

Telecom Billing

5G rollouts require real-time charging. Augmented Java engineers integrate FIS account data, build event-driven rating engines, and cut invoice cycles from days to minutes.

Transport & Logistics

Fleet finance modules on FIS are modernized by Java teams who create microservices for leasing, route-based invoicing, and blockchain tracking, ensuring global scalability.

Government & Public Sector

Pension and subsidy systems leverage outstaffed Java experts to replace monolithic FIS code, enforce security accreditation, and digitize citizen services swiftly.
