If you're dealing with messy manual processes, I turn them into clean, reliable automation systems. I build automation systems using n8n, GPT, and APIs that: Generate and enrich leads automatically Sync data across your tools (CRM, email, Google Sheets, etc.) Replace repetitive manual work with AI workflows Scale your operations without hiring more people Most automations break, are undocumented, or impossible to maintain. I build systems that are structured, scalable, fully documented, and easy for your team to manage. You own everything. What I typically build: Lead generation and enrichment pipelines Sales and CRM automation systems AI-powered inbox and support workflows Google Workspace and internal operations automation Data scraping and processing systems AI agents that take action across your tools How it works: Quick call to map your workflow and define the outcome. I build the system in n8n, test it with your real data, and iterate until it runs perfectly. Send me a message with what you want to automate. I'll tell you within a few hours if it's doable, how I'd build it, and what it would look like.
