Legacy System Integration

Innovation shouldn’t require a “rip and replace” strategy. We build secure API layers and middleware that allow modern AI tools to communicate seamlessly with your established mainframes and core systems.

Zero Disruption

We respect the "Do No Harm" principle. Our integration strategies wrap your existing core systems, allowing you to deploy new features without risking downtime on mission-critical mainframes.

Extend Asset Life

Maximizing ROI on your original investments. Instead of rewriting millions of lines of stable code, we unlock the value trapped inside them for modern applications.

Bank-Grade Security

Old systems often lack modern security protocols. We implement intermediate security layers that enforce encryption and modern authentication (OAuth2, OIDC) before requests ever reach your core.

Bridging the Gap to the Future

We engineer the digital connective tissue that links your rock-solid past with your agile future.

API Layer Development

"black box" systems into open platforms. We build RESTful or GraphQL API wrappers around legacy databases and services, making them accessible to web and mobile apps.

Mainframe Offloading

Reduce MIPS costs and improve performance. We architect solutions that cache read-heavy data in modern cloud databases, reducing the load on your expensive mainframe compute resources.

Real-Time Data Sync

Move from batch to real-time. We implement Change Data Capture (CDC) pipelines that stream data from legacy DB2 or IMS systems to modern analytics platforms instantly.

Microservices Decomposition

The "Strangler Fig" pattern. We help you gradually peel off specific functionalities from a monolithic application, rebuilding them as agile microservices while keeping the core running.

Cloud Hybridization

The best of both worlds. We design secure tunnels and networking architectures that allow your on-premise iron to interact securely with public cloud AI services (AWS, Azure, GCP).

UI/UX Modernization

Goodbye, green screens. We build modern, intuitive web interfaces that interact with the legacy backend, improving employee productivity and reducing training time.

Proven Impact

"Spectusop built a bridge to our 20-year-old core banking system in weeks. We launched our new mobile app without having to rewrite a single line of COBOL."

The Technology Behind the Bridge

Handling the complexity of AS/400, Mainframes, and SOAP so you don’t have to.

COBOL & PL/1 Logic Preservation

Your legacy code contains decades of refined business rules. We map these rules meticulously, ensuring that when we expose them via API, the output is mathematically identical to the original system.

Event-Driven Architecture

We utilize tools like Kafka or Solace to listen to legacy system events. Instead of waiting for a nightly batch job, a transaction on the mainframe triggers an immediate event for your AI fraud model to analyze.

Protocol Transformation

We handle the messy translation layer. Whether your system speaks SOAP, ISO 8583, fixed-width flat files, or XML, our middleware translates it instantly into clean JSON for modern developers.

Non-Invasive Testing

Testing against a live mainframe is expensive and risky. We create virtualized "mocks" of your legacy systems, allowing developers to test new features aggressively without ever touching the production core.

Identity Federation

We bridge the gap between RACF/LDAP legacy directories and modern SSO providers (Okta/Auth0). This ensures a user can log in once and securely access data across both modern and legacy environments.

Automated Documentation

Solving the "Knowledge Drain": Often, the engineers who wrote the legacy code have retired. As we integrate, we use AI to analyze the code and auto-generate modern documentation, recovering lost institutional knowledge.
