Modern Stack Systems

Modern Stack Systems is a Chicago based Salesforce consultancy and Select tier Salesforce partner, led by Mac Nosek, a 15x certified Salesforce Technical Architect. We build on every Salesforce cloud for small and mid-size companies: Sales Cloud, Service Cloud, Experience Cloud, Agentforce, Data 360 (Data Cloud), integrations and custom Apex and LWC development. We also build custom MCP servers that connect AI agents to Salesforce and other business systems. Every project is led by Mac directly, from discovery through go-live, with vetted contractors for delivery. Clients get a fixed scope, price and go-live date in writing before work starts. Engagements usually start with a Salesforce Health Check, move into a Launch project for new builds, and continue with Managed Services for ongoing admin, development and support.
