Integrations that keep working
Most enterprise software problems are really integration problems: data that should flow between systems and doesn’t, or does until a vendor changes a field. We build the connective layer carefully, with explicit contracts, defensive error handling and the monitoring to know when something drifts.
Typical engagements
- Exposing your platform: a public or partner API with authentication, rate limiting and documentation.
- Consuming third-party data: reliable ingestion of real-time or batch data, with fallbacks for provider outages. Our AlphaScreen build integrates live market data under heavy computational load.
- Connecting internal systems: syncing CRM, ERP and operational databases without manual exports.
- Preparing for modernization: wrapping a legacy system in a stable API before replacing it. See legacy modernization.
Often delivered as part of a broader custom software or web application project.
Capabilities
What we build and how we build it
01
API design
Consistent, versioned REST or GraphQL interfaces with clear contracts and published documentation.
02
Third-party integration
Connections to ERPs, CRMs, payment providers, market data feeds and vendor systems.
03
Event-driven workflows
Queues, webhooks and background jobs that move data reliably between systems.
04
Data synchronization
Idempotent syncs, conflict handling and reconciliation reporting.
05
Authentication and authorization
OAuth 2.0, API keys, scoped tokens, rate limiting and secure credential storage.
06
Observability
Structured logging, metrics and alerting so failures are visible before users report them.
Technology & Architecture
Technology we work with
- TypeScript
- Node.js
- Python
- PostgreSQL
- OpenAPI
- GraphQL
- Webhooks
- AWS
We choose tools to fit your environment, security posture, and team. If you have an established infrastructure, we build directly into it rather than introducing unnecessary dependencies.
