Systems Integration & Legacy Modernization

Tailored Integrations - Built around your exact workflows

Off-the-shelf connectors rarely fit complex business needs. We engineer custom APIs, adapters, and orchestration layers that respect your business rules and data models.

Custom API Development

Bespoke REST/SOAP APIs, OData feeds, and secure endpoints specific to your systems.

Business Logic Alignment

Integrations modeled after your rules, validations, and workflows—not generic defaults.

Custom ETL Pipelines

Transform, clean, and map your unique data structures with precision-built pipelines.

Security First

Hardened integrations with encryption, RBAC, audit trails, and compliance controls tuned for your environment.

Orchestration & Middleware - Custom layers, not generic tools

We develop middleware that exactly matches your infrastructure—ensuring data is normalized, validated, and routed in ways that align with your business needs.

API Gateway

Purpose-built routing, throttling, and transformations.

Workers

Custom job handlers for retries, batching, and error recovery unique to your systems.

Observability

Dashboards and alerts built to track what matters most to your operations.

Data Governance

Controls tuned to your compliance requirements and organizational policies.

Legacy & Proprietary - Bridging the old with the new

When vendors provide no connector, we engineer one. Our custom adapters, scripts, and ETL processes connect modern web-based services to legacy platforms, enabling seamless communication across eras of technology.

Custom Connectivity

Adapters for proprietary databases
SFTP/flat-file ingestion routines
Wrappers for outdated command-line utilities
Secure tunnels for on-prem only systems
Web-to-legacy connectors that link cloud applications with on-premise servers

Reliability Patterns

Replayable pipelines with error quarantine
Custom monitoring around brittle interfaces
Data validation routines unique to your formats
Feature-flagged deployments for safe cutovers

OmniSpear helped our company set up and configure, then migrate our websites onto new dedicated servers. They went above all expectations, working quickly and efficiently to accomplish this goal.

The best. OmniSpear provides the perfect blend of capabilities and cost consciousness. Big or small, they do it all.
