40+ AI employees deployed. 10 in my internal fleet. 30+ across 15 client production environments. 99.5% uptime over 12 months. They research leads, write outreach, publish content, run audits, monitor systems, and report back. Every day. Without supervision. Not chatbots. Employees that do work. A meta-agent on a single server dispatches tasks across my internal fleet, reviews output quality, and ships me one daily digest. The fleet handles a full sales pipeline (research → qualify → email → LinkedIn DMs), multi-platform content, SEO, job hunting, and proposal drafting. What I deploy: AI Sales Teams — Agents that research prospects, enrich with company intel, score against your ICP, then draft personalized cold emails and LinkedIn DMs. 5-touch drip sequences. Rate limiting. Pipeline tracking. Your human reps close. The AI does everything before that. AI Content Teams — Agents that research daily, draft platform-native content, run it through quality gates that catch AI slop, and publish on approval. I've built pipelines for LinkedIn API, X API v2, and Reddit with content rotation and topic cooldowns. AI Operations Staff — Health checks, data syncing, scheduled reports, system monitoring, compliance audits. They follow the process exactly, every time, and flag when something's off. Fleet Orchestration — When you have multiple AI employees, you need a manager. I build meta-agents that coordinate your fleet, dispatch work, evaluate output, and deliver a single daily digest of everything your AI workforce accomplished. Verticals shipped: tax firms (6-agent IRS forms / TaxDome / bookkeeping swarm), digital ad agencies (30+ accounts across Google Ads / GA4 / Meta / LinkedIn), DTC supplements (3-agent brand intelligence in UK / US / AU markets), home-services operators (CRM + SMS booking + browser automation), B2B SaaS dev teams, prediction markets, newsletters, lead generation. Why clients keep me on retainer: I operate, not just build. Most freelancers hand you a bot and disappear. I deploy on production infrastructure with health monitoring, auto-restart, secret management, and audit trails. I keep them running. I've done it for myself first. My own business runs on AI employees. Lead research, outreach, content, SEO, proposals. Every system I sell to clients, I've battle-tested on my own operations. I know what breaks. 40+ deployments taught me where agents fail: config coupling, context overflow, token expiry, rate limits, memory drift, browser session decay, OAuth refresh races. I've hit every failure mode and built recovery into the infrastructure. You're paying humans to do work that follows a process. I deploy AI employees that do it faster, cheaper, and without taking weekends off. Send a message with the repeating process you want owned. I'll tell you in 24 hours if it's a fit. 1.

Most AI freelancers will hand you a chatbot. I'll hand you a workforce. I architect and deploy production-grade multi-agent systems that run your operations 24/7: sales outreach, content engines, HR assistants, social growth, fleet orchestration. No overhead of human coordination. 6+ years shipping end-to-end products, from architecture to deployment to handoff documentation your team can actually maintain. What I've shipped recently: - FleetMind | Multi-agent orchestration on OpenClaw: CBDO Orchestrator routing tasks across Content, Social, Web, and SEO/GEO POD agents with regional execution (U.S. & E.U.), running 24/7 with CRM, WordPress, analytics, and social platform integrations. - PULSE | Autonomous X/Twitter growth engine on OpenClaw: 5-action AI agent generating voice-matched threads, monitoring niche trends, automating reply engagement, targeting ICP followers, delivering weekly analytics to Discord. Approval-gated, zero manual intervention. - AI HR Assistant | Multi-bot pipeline on OpenClaw: Orchestrator, Query Interpreter, Data Retrieval, and Response Formatter bots. Natural language queries for leave balances, payroll, deductions. REST API + CLI with HRIS integration path. - AI Sales Outreach Agent | End-to-end pipeline: Research Agent scrapes prospects, Personalization Agent crafts context-aware emails, Delivery Agent handles SMTP with scheduling/throttling/tracking, Orchestrator manages retries and error handling. - AI Reality Show | Multi-agent investor simulation: autonomous AI avatars on Google Meet running real-time due diligence, contextual feedback, and investment decisions. OpenAI reasoning + ElevenLabs voice + Hedra avatars, fully autonomous with manual override. 🔧 WHAT I BUILD OpenClaw Agent Systems Custom multi-agent architectures: Director/Specialists/Auditor patterns, fleet orchestration, inter-agent communication, shared memory, approval gates. Full lifecycle from architecture to skills security audits, secrets handling (least-privilege), reliability infrastructure (health checks, logging, alerting), and handoff docs. n8n Workflow Automation Production workflows connecting CRMs, payment processors, marketing platforms, databases. Error handling, retry logic, webhook orchestration, custom JavaScript nodes, AI/LLM integration. Make/Zapier to self-hosted n8n migration included. LLM Applications & RAG Pipelines End-to-end RAG with vector stores (pgvector, Pinecone, Weaviate), embeddings, semantic search, prompt optimization. Multi-model (Claude, GPT-4, Gemini). Fine-tuning, evals, tool/function calling. Voice AI & Conversational Systems Voice agents with ElevenLabs, TTS pipelines, real-time conversational AI integrated into multi-agent workflows. Full-Stack Infrastructure React/Next.js, Node.js/NestJS, PostgreSQL/MongoDB/Redis. AWS/GCP deployment. Docker, CI/CD, self-hosted LLM infrastructure. 💡 WHY ME Architecture-first. Every engagement starts with a diagnosis. I map your processes, identify automation opportunities, then design systems that solve the actual problem, not just what's in the brief. Production-grade, not demos. Health monitoring, error recovery, logging, alerting. Every deployment includes handoff documentation and team walkthrough so you're never dependent on me. Full-stack delivery. Agent architecture to API integrations to frontend dashboards. I ship the complete system, not just the AI piece. No coordination overhead with multiple freelancers. Operational maturity. Multi-agent fleets running 24/7 in production. I build for reliability from day one: least-privilege access, approval gates, stateless job design. 🛠 TECHNICAL STACK AI & Agents: OpenClaw, LangChain, LangGraph, Claude API, OpenAI API, RAG, MCP, Prompt Engineering, Multi-Agent Orchestration, ElevenLabs, Fine-tuning Automation: n8n, Workflow Orchestration, Webhook Design, API Integration Backend: Node.js, NestJS, Python, FastAPI, TypeScript/JavaScript Frontend: React, Next.js, React Native Databases: PostgreSQL, MongoDB, Redis, pgvector, Pinecone, Weaviate Infrastructure: AWS, GCP, Docker, CI/CD, Self-hosted LLM Infrastructure 📌 OpenClaw, AI Agent Development, Multi-Agent Systems, AI Automation, n8n Automation, Workflow Automation, LangChain, LangGraph, RAG, Retrieval Augmented Generation, MCP, Model Context Protocol, Claude API, OpenAI API, GPT-4, LLM Integration, Prompt Engineering, Fine-tuning, Voice AI, ElevenLabs, Conversational AI, Vector Database, Semantic Search, Embeddings, API Integration, REST API, Full Stack Development, SaaS Development, Business Process Automation, Lead Generation Automation, Sales Automation, CRM Integration, Agentic AI, Custom AI Solutions, Make, Zapier, GoHighLevel, Salesforce Integration
