System Integration Services
Make your stack work as one, without disrupting what already runs the institution.
Velmie delivers system integration services for banks, EMIs, fintechs, and program managers that need predictable delivery across core platforms, payment rails, card processors, KYC and AML providers, and digital channels.
Remove friction from complex initiatives
Integration programs fail when ownership is unclear, dependencies are unmanaged, and delivery is treated like a series of point connections. We provide end to end leadership and engineering execution, so integrations are designed, built, tested, and handed over with operational discipline.
Core services
✓ Integration architecture and blueprinting
Define target state integration patterns, system boundaries, data ownership, and sequencing. Align technical decisions to operating models, compliance constraints, and roadmap reality.
✓ Core banking and ledger integration
Connect channels and services to core and ledger platforms with clear contracts, versioning, and controlled change, while protecting stability in systems of record.
✓ Card and issuing ecosystem integration
Integrate payment processors, ACH and SEPA flows, real time rails where applicable, and reconciliation interfaces, with predictable error handling and traceability.
✓ Card and issuing ecosystem integration
Integrate card processors, tokenization services, spend controls, dispute workflows, and event driven updates into a coherent channel and operations experience.
✓ KYC, AML, and fraud ecosystem integration
Connect identity, verification, screening, and risk signals into onboarding and servicing workflows while preserving auditability and minimizing friction.
✓ Data integration and operational reporting
Standardize critical entities, implement data pipelines where needed, and ensure operations teams can rely on consistent reporting and reconciliation of outputs.
Select a service area to go deeper
Choose the engagement focus that matches your initiative and delivery maturity.
✓ Professional services for delivery ownership
Program leadership, integration design authority, engineering execution, and coordination across internal and vendor teams, with clear milestones and governance.
✓ Staff augmentation for specialized capacity
Targeted engineering, QA, and integration expertise embedded into your delivery organization to accelerate progress without compromising standards.
✓ Technology refresh and modernization support
Incremental modernization that reduces dependency risk and unlocks new capabilities while keeping critical systems stable.
Built for operational reality
Integration is not complete at go live. It must be operable.

Traceability for audit and troubleshooting
Delivery approach
1. Discovery and integration mapping
We map target journeys, systems of record, provider touchpoints, non-functional requirements, and delivery constraints, then define an executable plan.
2. Design and implementation
We implement the agreed patterns, connectors, transformations, and orchestration needed for your scope, with disciplined reviews and documentation.
3. Testing, cutover, and handover
We run integration testing, performance validation, and cutover planning, then complete operational handover with runbooks and support readiness.
