Hi, I'm Maxi 👋 I build AI agent systems & Custom software that have generated millions for 7-and 8-figure agencies. → Built AI agents for CHANEL ($58B+ market cap) and Cherre ($300M+ market cap) → Consulted with 8-figure tech companies working with HP, Unilever, Nestlé, L'Oréal → Saved $733k by rebuilding an entire ClickUp system for a Marketing Agency → Official ClickUp Verified Consultant & Make com Advanced Partner Founder of Floclick, driving $16.3M+ in client growth through AI-powered systems. ——— Here's what I actually do (and how I can help you): Hey, I'm Maximilian (most people call me Max) I've spent the last few years building AI-powered operations systems for agencies that need to scale without losing their minds. I work with companies doing $1M, $50M+ annually, helping them automate the repetitive stuff so their teams can focus on what actually makes money. I've built systems for 65+ companies, including household names like CHANEL, Cherre, and worked with an 8-figure tech firm that services Unilever, Nestlé, L'Oréal, and HP. What I'm best at: I build custom AI agent systems using Claude Code, GPT-5, and advanced automation platforms. This usually means: - AI agents that handle lead qualification, outreach, and follow-up (fully personalized at scale) - End-to-end CRM systems in HubSpot, Monday, ClickUp, or Salesforce that actually get used - Complex automation workflows in Make .com, N8N, or Zapier with custom API integrations - ClickUp workspace builds with automated dashboards, time tracking, and client reporting - Intelligent billing systems, onboarding flows, and project management setups - Fully custom Claude Code Agents for businesses I'm currently ranked #1 contributor in Nick Saraev's 2,200+ member operations community, where I regularly advise agencies on scaling their operations with AI and automation. I also run a YouTube channel focused on CRM systems, project management, and AI automation, where I break down how these systems actually work behind the scenes. @maximilianlesek I've worked with pretty much every major CRM and PM tool out there: Monday, Asana, Trello, ClickUp, Airtable, Salesforce, GoHighLevel. When standard integrations don't cut it, I build custom API solutions. If you're looking for someone who builds systems that actually last, that's what I specialize in. Happy to chat about your specific needs. / Maxi

I help companies fix and scale Salesforce systems. Especially when integrations, automation, or data flows don’t work as expected. Over the past 15+ years, I’ve worked with startups, mid-size companies, and enterprises, turning Salesforce into a reliable system of operations, not just a CRM. Most of my work focuses on integrations, process automation, and cleaning up complex or underperforming setups. I’ve helped teams fix broken integrations between Salesforce and tools like HubSpot, NetSuite, and other APIs, clean up messy data after migrations, improve data integrity, and build scalable automation using Flows and Apex. I also work on optimizing lead routing, pipeline visibility, reporting, and connecting Salesforce with external systems. My core expertise includes Sales Cloud, Service Cloud, Experience Cloud, Marketing Cloud / Account Engagement (Pardot), CPQ, Nonprofit Cloud, Litify, AppExchange app development, integrations, automation, and data migration. From a technical perspective, I work with Apex, Lightning Web Components (LWC), Aura, Visualforce, Salesforce Flow (record-triggered and screen flows), Platform Events, REST/SOAP APIs, webhooks, data modeling, validation rules, and process automation. I have hands-on experience integrating Salesforce with platforms like HubSpot, NetSuite, SAP, Stripe, Twilio, DocuSign, PandaDoc, Celigo, Zapier/Make, FormAssembly, Formstack, WordPress, and OpenAI / ChatGPT. I focus on building systems that are stable, scalable, and actually used by teams, not overengineered solutions that break over time. If you’re dealing with a messy setup, broken sync, or need to build something reliable from scratch, happy to discuss.
