Modern Stack Systems is an architect-led Salesforce, cloud and AI engineering firm. Every engagement is designed and led by Maciej Nosek, a 15x certified Salesforce Technical Architect with 10+ years on the platform, and delivered by a senior, 100% US-based team. Salesforce Partner on AppExchange. Salesforce is where most clients start, but the work goes well past the CRM: AWS, AI, databases, and the websites and apps around them. Some clients bring us in for a new org or a new cloud. Some need a project rescued. Others, including consulting firms, want senior architects and developers working alongside their own team. HOW WE WORK Engagements range from one fixed-scope project to a dedicated team on a long-running program. Fixed-scope work starts with a written scope and quote. Managed services put a standing senior team on your systems every month, sized to your roadmap. Everything else runs time and materials, with the architects, developers and admins the work calls for. WHAT WE BUILD On Salesforce we cover every cloud and the engineering underneath it: data model, security and sharing, Flow, Apex, LWC, integrations and DevOps. In AI we build Agentforce agents, custom agents, RAG over your own content, and custom MCP servers that connect Claude and other agents to your systems. On AWS we build serverless applications and event-driven integrations. We also design and build websites and web apps, and take on database design and administration. WHEN TEAMS CALL US You're standing up a new Salesforce org and want it built right the first time. A project needs a rescue: late, over budget, or a system nobody trusts. An Agentforce or AI pilot hasn't made it to production. The roadmap is bigger than the team, and hiring would take months. Every engagement starts with a free 30-minute discovery session. We look at your systems, scope the work, and tell you where Salesforce or AI will help and where it won't. Book a call: https://calendly.com/mac-nosek/30min
