Former director of a $35M+ D2C portfolio, now helping business owners unlock growth and save ridiculous amounts of money with AI automation. ✅ Retained $521K annually for $35M+ portfolio with AI-driven automation ✅ Saved a healthcare agency $48K+/year with HIPAA-compliant systems ✅ Unlocked ad scaling for a 7-figure D2C brand with an offline attribution system Hi, I'm Dylan 👋🏻 Most of my clients come to me with a problem and lack clarity on the best solution. My job is to understand your business first: your processes, your bottlenecks, and then design the right strategy for your specific context. The build is the easy part now. Anyone with Claude and a weekend can wire together a basic workflow. The harder part is strategic: figuring out where automation actually fits, where an agent makes sense, which tools to use, where human judgment still needs to stay in the loop, and most importantly; the real value add for your business. That's where most freelancers get stuck, and where I bring the most value. I also think it's my job to tell you what not to build. There's a lot of noise in the AI space, overpromised tools and half-baked automations looking for a problem to solve. I stay up to date on what's actually production-ready so I can give you an honest read on what will work and what won't. One more thing worth mentioning: I come from an operator background. I led operations for a $35M+ portfolio before going full-time into AI automation. That means I look at your business from a strategic, birds-eye view first, not just at your tech stack. 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 𝗜 𝗕𝘂𝗶𝗹𝗱: • HIPAA-compliant healthcare automation (EVV, timesheets, clinical reporting, EHR integration) • Payment reconciliation and bookkeeping automation (QuickBooks, Xero, EOPs) • Lead generation and outreach pipelines (Apollo, Apify, Clay, Instantly, AI personalization) • CRM and sales automation (GoHighLevel, lead scoring, pipeline routing, follow-ups) • AI agents and agent networks using Claude Code, skills, and custom directives • Voice agents for sales, support, and customer service workflows • E-commerce attribution and fulfillment systems (Shopify, Google Ads API, Klaviyo, n8n) • Reporting dashboards and document automation (Google Sheets, Apps Script, Zoho Sign) Most of my production builds run as a combination of n8n for orchestration and Claude Agents hosted on Modal for the AI layer. This lets systems run 24/7 on triggers and schedules, not just when you're at your desk. Healthcare is the vertical I go deepest on. I've built HIPAA-compliant systems for home care agencies handling EVV timesheets, clinical reporting, insurance claims processing, and EHR integration. If you're in a regulated space and need automation that won't break compliance, this is where I spend most of my time. Every delivery includes clear documentation and Loom video walkthroughs so your team can maintain it without me. Looking for clients who want a long-term partner, not just someone to execute a ticket. Cheers, Dylan
