About this gig

Your systems work. They just need to talk to each other.


If you need to connect your CRM, ERP, website, marketplace, payment system, communication platform, or another third-party service, I can build the integration around the way your systems actually need to exchange information.


I build API and system integrations for businesses that need reliable data flow between the tools they already use.


What I can integrate:

  • REST and GraphQL APIs
  • CRM and ERP systems
  • Ecommerce and marketplaces
  • Payment gateways
  • WhatsApp and communication services
  • OAuth and authentication
  • Webhooks and event-driven workflows
  • Databases and internal applications
  • Custom third-party APIs
  • Data synchronization between systems


The work can include authentication, data mapping, webhooks, error handling, retries, background jobs, and the application logic around the integration.


If you already have the systems and need them connected, or you need an API built for your own application, message me with the systems involved and what you want them to do.

We build custom CRM systems, internal business software, web applications, eCommerce platforms, and workflow automation. From admin dashboards and customer portals to order management, inventory tracking, payment integrations, reporting, and operational workflows, every system is built around how your business works. Got something that doesn't fit into existing software? That's usually where we come in. Whether you're replacing an outdated system or building something from scratch, we work with you to figure out what needs to be built, then turn it into software your team can actually use.
