WHAT WE BUILD_

Your integration layer,
engineered right

Cloud to on-prem, API to ERP, legacy to modern. We cover every layer.

One cloud or five, it all works together

Most teams run AWS, Azure, and GCP simultaneously with zero coordination between them. We build the connective layer so data flows cleanly, in real time, across every environment.

  • Multi-cloud orchestration
  • Cloud-to-on-prem connectivity
  • Observability and alerting
  • Real-time event streaming
  • Serverless function integration
  • Data pipeline sync
  • REST
  • GraphQL
  • MCP
  • gRPC
  • OAuth 2.0
  • OpenAPI

APIs built for products, not just requests

We build and document production-ready APIs from the ground up. We also implement the Model Context Protocol so your internal systems become accessible to AI agents, not just developers.

  • RESTful API design and development
  • MCP server implementation
  • OAuth 2.0 and access control
  • GraphQL schema and federation
  • Event-driven and webhook systems
  • OpenAPI documentation
  • AWS
  • AZURE
  • GCP
  • SERVERLESS
  • KAFKA
  • datadog

Old tech, new connections. No rip and replace

Your ERP took years to implement. Your mainframe still runs critical ops. We wrap both in modern APIs so new and old work together and your team stops re-keying data.

  • ERP and mainframe API wrapping
  • ETL pipeline design
  • Middleware and ESB setup
  • SOAP to REST conversion
  • Bi-directional data sync
  • Incremental modernization
  • SAP
  • Oracle
  • IBM AS/400
  • MuleSoft
  • EDI
  • Talend

Your SaaS stack, finally talking to itself

Every business runs 5 to 15 SaaS tools. Most of them are siloed. We build purpose-built connectors between your CRM, ERP, payments, and support platforms. Monitored from day one.

  • CRM: Salesforce, HubSpot, Pipedrive
  • Payments: Stripe, Chargebee, Zuora
  • Support: Zendesk, Intercom, Jira
  • ERP: NetSuite, SAP, Dynamics 365
  • Comms: Twilio, SendGrid, Slack
  • Custom connectors for any API
  • Salesforce
  • HubSpot
  • NetSuite
  • Stripe
  • Zendesk
  • Shopify

Reliable data in actionable insight out

Integration without data quality is just faster chaos. We build ETL and ELT pipelines that move, transform, and validate data reliably between your systems and your reporting layer.

  • ETL and ELT pipeline development
  • Real-time and batch processing
  • Data validation and deduplication
  • Data warehouse integration
  • BI tool connectivity
  • Scheduled jobs with failure alerts
  • Snowflake
  • BigQuery
  • Redshift
  • dbt
  • Airflow
  • Power BI

Sound familiar?_

The real cost of a disconnected stack

These come up on almost every discovery call. If any of this is your reality, you need integration, not more tools.

01

Your team re-keys data between systems manually.

Hours lost every week. Every manual step is a chance for error, delay, and a frustrated ops team.

02

You have 12 tools. None of them talk to each other.

CRM doesn’t know what finance knows. Every new SaaS adds another silo to manage.

03

One legacy system is blocking everything else.

You can’t modernize because the old system runs payroll. And nothing talks to it cleanly.

How it works_

From tangled to connected

Low-disruption delivery from day-one audit to post-launch monitoring.

Audit and Map_

We document your systems, data flows, and integration gaps before writing a single line of code.

  • System map
  • Gap analysis
  • Scope doc

Design Architecture_

We pick the right pattern: event-driven, API-first, or middleware. Scoped to your stack and scale.

  • Architecture doc
  • API contracts
  • Integration plan

Build and Test_

CI/CD from the start. Every integration is load-tested and peer-reviewed before touching production.

  • CI/CD pipeline
  • Load tests
  • Peer review

Deploy and Monitor_

Go live with dashboards, alerts, and SLA commitments. Support starts from day one post-launch.

  • Live dashboards
  • Alert rules
  • SLA commitments
