Enterprise Integrations, Communication & Operations Platform

Sanitized professional case study based on enterprise recruitment/platform experience. Client names, internal data, screenshots, credentials, and exact metrics are intentionally omitted; this page describes public-safe architecture, responsibilities, and delivery patterns.

One-line summary

The integration layer that connects communication channels, vendor workflows, and business operations to the CRM/ATS, so activity and records stay in one place.

Problem

A recruitment business runs on more than its CRM: calls, email, SMS, WhatsApp, vendor workflows, and invoice/GST operations all generate activity that needs to land against the right records. Done by hand, that activity is lost or inconsistent, and every new channel becomes another silo.

Solution

• Communication integration — email, calling, SMS, and WhatsApp through providers such as Microsoft Graph, Twilio, MSG91, SendGrid, 3CX, and RingCentral, with communication activity synced back to CRM/ATS records.
• Vendor & operations — vendor management workflows and invoice/GST portal integrations connected into the business-process layer.
• Integration layer — REST APIs and a consistent integration pattern so new channels and workflows plug in without one-off glue each time.

Built across .NET and Node.js services.

My role

Solution architecture and delivery: the integration patterns, the API contracts between channels/providers and the CRM/ATS, and guiding the .NET/Node.js implementation that keeps activity in sync.

Tools

Microsoft Graph, Twilio, MSG91, SendGrid, WhatsApp APIs, 3CX, RingCentral, vendor-management and invoice/GST portal integrations, REST APIs, .NET, and Node.js.

Intentionally omitted

Client names, provider account detail, credentials, internal data, screenshots, and specific third-party portal names. Integrations are described by capability, not proprietary configuration.
