A production-grade, multi-tenant SaaS platform powering B2B sales pipeline management for companies across Europe. Full-stack development from database design to deployment.
The Challenge
Atlas Analytics needed a unified platform to manage outbound sales campaigns, track pipeline metrics, and provide real-time analytics to multiple client organizations — each with isolated data, custom roles, and unique workflows. The existing tooling was fragmented across spreadsheets and disconnected services.
What I Built
Built the complete Atlas SalesOS platform as the core developer:
• Designed and implemented multi-tenant architecture with strict data isolation using Supabase row-level security policies
• Built interactive statistical and mathematical dashboards for real-time campaign performance tracking
• Developed CRM-style modules including contact management, pipeline views, and activity tracking
• Implemented role-based access control with granular permissions per organization
• Created complex data tables with advanced filtering, sorting, and bulk operations
• Integrated Smartlead for email campaign management and Cloudtalk for call tracking via REST APIs and webhooks
• Built automation workflows using Make.com and n8n for lead enrichment, campaign triggers, and reporting
• Designed responsive UI with Next.js, React, and TypeScript following a component-driven architecture
