About this Gig
Most businesses today use 5-15 different tools.
CRMs, payment gateways, marketing platforms, databases, internal systems and none of them talk to each other properly.
We design and build secure, production-grade API & system integrations that connect your entire stack into one smooth workflow.
We specialize in Node.js & TypeScript based backend systems and build integrations that are scalable, maintainable, and production-ready.
What we build:
- SaaS platform integrations
- CRM, ERP & internal system connections
- Payment system integrations (Stripe, PayPal, etc.)
- Marketing & analytics tool pipelines
- Automation workflows & event-driven systems
- Webhook systems & async task processing
What you get:
- Clean architecture
- Secure API handling
- Scalable system design
- Production-ready deployment
- Clear documentation
We don't build fragile automations.
We engineer reliable system-level integrations designed for long-term usage.
If your tools don't talk to each other we fix that.
