- Connectors for SWIFT, ISO20022, payment processors, card schemes, and legacy FTP/SFTP feeds.
- Event-driven architectures using Azure Event Hubs / Service Bus for scalable, decoupled integrations.
8. Migration, Modernization & Re-architecture
- Incremental migration from legacy stacks to .NET Core and Azure with strangler patterns.
- Re-architecture to microservices, containerization (Docker), Kubernetes orchestration (AKS), and service mesh where needed.
- Database migration strategies, data mapping, reconciliation checkpoints, and rollback plans.
9. DevOps, SRE & Managed Operations
- CI/CD pipelines (Azure DevOps / GitHub Actions), automated testing, infrastructure as code (Terraform).
- SRE practices, performance tuning, monitoring (Application Insights, Prometheus, Grafana), and error budgets.
- SLA-backed managed services, incident response, and disaster recovery planning.
Why we choose .NET
- .NET provides deterministic performance, robust concurrency primitives, and mature tooling for reliable financial systems.
- C# and the .NET ecosystem offer proven libraries for data access (Entity Framework), cryptography, and high-performance networking.
- Azure managed services (SQL Database, Key Vault, Event Hubs, Service Bus, AKS) accelerate delivery while meeting enterprise security controls.
Security & Compliance
- PCI-DSS for payment flows, TLS everywhere, and tokenization for card data.
- End-to-end encryption, HSM integration, and centralized key management (Azure Key Vault).
- Role-based access control (RBAC), multi-factor authentication (MFA), and fine-grained authorization.
Performance & Scalability
- Architectures designed for horizontal scaling, autoscaling rules, and stateless services where possible.
- Caching (Redis), data partitioning, and read replicas for SQL Server to reduce latency.
- Benchmarked load testing, capacity planning, and tuning for sub-second response SLAs in trading scenarios.
Engagement Models & Commercials
- Dedicated Offshore Development Teams: Embedded .NET developers, QA, DevOps, and product roles roadmap execution.
- Fixed-Scope Projects: Defined deliverables, milestones, and acceptance criteria for specific product outputs.
- Time & Material: Flexible engagement with transparent hourly rates and rolling commitments.
Operational Guarantees & IP
- Full code ownership and IP assignment to the client on delivery.
- Secure onboarding, NDAs, and access controls before any sensitive data exchange.
- Comprehensive documentation, runbooks, test coverage, and knowledge transfer sessions.
Sample Case Snapshots
- Core ledger modernization: Migrated a regional bank’s batch ledger to a streaming event-driven ledger on .NET and Azure Event Hubs. Result: reduced nightly processing windows by 70% and improved reconciliation accuracy.
- Payment gateway build: Developed a PCI-compliant gateway with tokenization and retry logic, cutting reconciliation errors by 45% and enabling instant settlements.
- Trading analytics layer: Implemented a streaming analytics pipeline for market signals with sub-second processing, enabling algorithmic strategies to operate reliably under load.
FAQs about Financial Software Development
Yes, we design both multi-tenant and single-tenant architectures based on isolation and compliance needs.
SQL Server for transactional core systems (with partitioning and read replicas); Cosmos DB or other cloud-native stores for geo-distributed workloads when needed.
Dual-writing, reconciliation windows, checksum validation, and rollback procedures ensure safe migration with traceable verification.
