Upgrade legacy systems without the risk.
We modernise outdated applications, migrate monoliths to microservices, and upgrade technology stacks incrementally — all while keeping your business running without interruption.
// API Gateway — Strangler Fig Route Splitting
const gateway = new APIGateway({
routes: [
{ path: "/api/v1/orders", target: "modern-orders-service" },
{ path: "/api/v1/inventory", target: "legacy-monolith" },
{ path: "/api/v1/customers", target: "modern-customer-service" },
],
fallback: "legacy-monolith",
rollback: { enabled: true, threshold: "5xx > 1%" },
});Strangler Fig Migration
Gradually replace legacy components with modern services behind an API gateway. Each route is migrated independently, allowing instant rollback and zero-risk deployments.
Tools & Frameworks We Engineer With
Migration
- Strangler Fig: Incremental legacy replacement pattern
- API Gateway: Route-level traffic splitting and rollback
- Event Sourcing: Capture state changes as immutable events
- CQRS: Separate read and write models for scalability
Modern Stack
- Next.js: React framework for server-rendered applications
- NestJS: Enterprise-grade Node.js backend framework
- TypeScript: Type-safe development across the stack
- GraphQL: Flexible API layer for modern frontends
Database
- PostgreSQL: Enterprise relational database
- Redis: In-memory caching and session store
- Prisma: Type-safe ORM for database access
- Data Migration Tools: Automated schema and data migration
Infrastructure
- Docker: Containerised application packaging
- Kubernetes: Container orchestration and auto-scaling
- Terraform: Infrastructure as code provisioning
- CI/CD: Automated build, test, and deploy pipelines

We use the strangler fig pattern to migrate incrementally, one service at a time. Each migration step includes automated rollback capability, parallel running validation, and comprehensive regression testing — so your business is never at risk.
Timelines vary by system complexity. Small monoliths can be modernised in 3-6 months, while large enterprise systems typically take 9-18 months. Our incremental approach means you start seeing benefits from sprint one, not just at the end.
We implement dual-write patterns with automated reconciliation. Every record is checksummed and validated in both systems. We run parallel comparisons on millions of transactions before cutover, ensuring 100% data integrity.
We provide comprehensive training on the new technology stack, architecture patterns, and operational procedures. This includes hands-on workshops, documentation, and a transition period where our team supports yours until full independence.
