Our pre-vetted Java specialists—each battle-tested on Temenos T24 data-migration, IRIS and COB interfaces—plug into your sprint in ≤48 hours, billable only for productive time. No severance, no local compliance risk, fully transparent rates. Scale squads up or down as release dates shift, keep IP protection with airtight NDAs, and pay zero recruiter fees. In short, you receive the speed of a contractor with the loyalty of an employee, all under one flexible MSA.

Retail Banking

Retail banks rely on Temenos T24 Core Banking Migration developers to re-platform legacy deposits, loans and card modules onto Temenos Transact. Augmented Java teams build batch interfaces, REST APIs and CX widgets, ensuring Japanese FISC compliance while minimising branch downtime.

Neobanks & FinTech

Digital-only banks integrate Temenos with Kotlin/Java micro-services for onboarding, AML and real-time risk. Augmentation cuts runway burn, letting founders scale squads only when new funding drops.

Broker-dealers upgrade settlement engines to Temenos Securities while Java specialists craft low-latency FIX gateways and Kafka streaming, meeting TSE clearing SLAs.

Insurance

Insurers tap Temenos T24 Migration developers to unify policy, claims and billing data into a single core, replacing host AS/400 RPG code with resilient Spring jobs.

Payments

PSPs need ISO 20022 converters and real-time fraud rules. Java outstaffers extend Temenos Payment Hub and certify against Zengin-Net domestic clearing.

Wealth Management

Private banks consolidate portfolio accounting onto Temenos WealthSuite; augmented engineers code Java micro-front-ends and GraphQL feeds for robo-advisors.

Micro-finance

MFIs migrate to Temenos Infinity with lightweight Java services for SMS lending, ensuring low-resource devices stay performant in rural Japan.

RegTech

Regulatory platforms embed Temenos T24 data pipelines written in Java to auto-generate JFSA reports, reducing audit cycles.
