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.

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
