Autonomous Business Operations System
Your entire back-office, running as software. I design and deploy a team of specialized AI agents that handle marketing, copywriting, video editing, ads, and data integrity — coordinated by a central orchestrator. You just describe what you need, in plain language.
- Custom multi-agent architecture (9+ specialized roles)
- Central orchestration hub, single point of command
- n8n + API integration layer across your whole stack
- Automated data-integrity checks & sync auditing
- Runbooks so the system keeps running without you
Lead Generation & Prospect Intelligence
Stop guessing who to contact. I build automated prospecting engines that search LinkedIn, Google Maps, and B2B directories against your ideal customer profile, score every match, and hand you a ranked, ready-to-approach list.
- ICP-based search across LinkedIn, Maps & B2B directories
- Fit scoring (0-10) with hot/warm/cold classification
- Contact enrichment (email, phone, socials)
- Export to CRM-ready CSV/JSON + summary report
- Reusable weekly to keep the pipeline fresh
Systems Architecture & Technical Consulting
Already have systems in place but not sure they're built right? I audit your stack, map failure points, and design the architecture that gets you from fragile to production-grade — before you spend a cent building it.
- Full technical audit of existing automation/systems
- Failure-point & single-point-of-failure mapping
- Architecture design docs before any code is written
- Vendor/build vs. buy recommendations
- Fixed-scope advisory engagements, no retainer lock-in
