Overview
Designed and implemented a suite of third-party integrations connecting the SalesOS platform to external services for communication, analytics, and campaign management.
The Challenge
Atlas SalesOS needed to function as the central hub for sales operations, but critical data and functionality lived in separate platforms — Smartlead for email campaigns, Cloudtalk for phone calls, and various data providers for lead enrichment. Manual switching between tools was causing data inconsistencies and lost context.
What I Built
Built a robust integration layer within the SalesOS platform:
• Designed RESTful API architecture for bidirectional data flow with Smartlead and Cloudtalk
• Implemented webhook receivers for real-time event processing (email opens, replies, call completions)
• Built data transformation pipelines to normalize external data into the SalesOS schema
• Created a unified activity timeline aggregating events across all connected platforms
• Implemented rate limiting, retry logic, and circuit breaker patterns for API reliability
• Set up monitoring and alerting for integration health
