The founder
About Modern Stack Systems
An architect-led Salesforce and AI consultancy. US-based, and you work directly with the architect.
Mac (Maciej) Nosek
Founder, 15x certified Salesforce Technical Architect
Background
A decade building on Salesforce, for companies from mid-market to the Fortune 500.
Modern Stack Systems is led by Mac Nosek, a 15x certified Salesforce Technical Architect. The work covers architecture, Apex and Lightning Web Components, integrations, Agentforce, and the AWS and AI systems that sit around an org.
We work in small steps that ship. Most Salesforce trouble comes from trying to do everything at once, so we scope tightly, deliver, measure, and then decide what is worth building next. You stay focused on running your business while the platform catches up to it.
If you need something we do not do, we will say so and point you to someone who does.

How we work
The same four commitments on every engagement.

- Included with every engagement. Real scoping on your org, not a sales pitch.

- Central time, working across every US time zone. Onshore senior specialists join when the scope needs them.
