Is your AI agent a production system or a fragile demo? Most AI agent projects collapse the moment they hit real traffic. 🏆 20+ years architecting production systems at principal engineer level 📊 $100K+ earned on Upwork across 32 architecture projects 🎯 100% Job Success Score, Top Rated Plus on Upwork ⚡ Built an MCP server connecting AI agents to live financial operations on Solana 💼 CEO at Osambit, a 20-person AI agent engineering team ✅ Enterprise Blockchain Architect certified, former Sr Principal Engineer at Nordstrom ⭐⭐⭐⭐⭐ "We've had the opportunity to collaborate with the Osambit team, and it's been a great experience. They're highly professional, responsive, and truly understand the final goal. Their technical expertise and ability to deliver on time have been key to the success." (Alwyn V., IXO World) As an AI Agent Architect with 20+ years of production engineering experience, I build AI agent systems using LangGraph, LangChain, and MCP that run in production, not prototypes that die in demos. Every AI agent project I take on starts with a decision graph - what the AI agent handles autonomously, what escalates to a human, and where it fails safely. That architecture-first approach is why my AI agent systems survive real traffic while cheaper builds collapse on edge cases. 🔶 IXO World (AI agent architecture): full-time Q4 2024 engagement | delivered on time | team collaboration verified by client testimonial above 🔶 Meteora + proprietary DLMM protocol (AI agent + DeFi automation): $81K engagement | MCP server linking AI agents to live trading operations | real-time autonomous execution with human-in-the-loop safeguards 🔶 Roover.AI (AI agent system architecture): intelligent B2B2C roof estimation platform | multi-modal RAG pipeline design | production deployment 🔶 Nordstrom (Sr Principal Engineer, 5 years): architected 9+ enterprise systems | supported 10 offshore engineering teams | supply chain, payment, logistics domains WHAT I DO ✅ AI Agent Architecture: decision graph design, multi-step workflow orchestration, human-in-the-loop control for every AI agent system ✅ LangGraph & LangChain Systems: production AI agent pipelines with state management and tool connectivity ✅ MCP Server Development: Model Context Protocol servers connecting AI agents to real business systems ✅ RAG Pipelines: retrieval-augmented generation grounding LLM answers in your knowledge base ✅ Multi-Agent Orchestration: CrewAI, LlamaIndex, and custom AI agent orchestration for complex agentic AI workflows ✅ AI Agent Security Hardening: prompt injection defense, data leakage prevention, auditability ✅ LLMOps & Production Deployment: tracing, observability, evaluation frameworks, regression testing for AI agent systems ✅ OpenAI & Claude API Integration: enterprise-grade AI agent integration with cost, latency, and failure-mode management WHO I WORK WITH 🎯 B2B and B2C companies building AI agent products, not one-off assistant setups 🎯 Founders and CTOs who need AI agent systems running in production with real users 🎯 Teams with multi-week engagements (4+ weeks minimum), not 5-minute tasks 🎯 Companies that understand AI agent architecture is a design problem, not a prompt problem 🎯 Clients who value senior engineering judgment over the cheapest hourly rate MY PROCESS 1️⃣ Architecture Review: 24-hour turnaround on a decision graph, failure-mode map, and scope estimate for your AI agent project 2️⃣ Design: AI agent flow specification, tool boundaries, escalation rules, evaluation plan 3️⃣ Build: production AI agent system with observability, security, and regression tests from day one 4️⃣ Deploy & Iterate: staged rollout, LLMOps monitoring, iterative refinement of the AI agent based on real usage Send me a message or invite me to your AI agent project.

Most AI agents that touch real money or production APIs get drained, jailbroken, or hallucinate destructive actions within their first month live. I'm the engineer who fixed that. ✅ Top Rated Plus | 100% Job Success | 8+ years shipping production AI + blockchain ✅ Author of DCP — the first open-source security layer for AI agents (2026) ✅ Founder-engineer at 1ly.store — live AI agent commerce marketplace (MCP + USDC) ✅ Clients I've engineered for have raised $43M+ combined ✅ One agent I shipped onboarded 20,000 users in week one DCP (Delegated Custody Protocol) is the project I'm most known for right now. It's a local-first encrypted vault where agents NEVER hold your keys: Agent requests → Vault approves & executes → Agent gets only the result. It's becoming the default primitive for builders shipping agents that actually do things — not just chat. ────────────────────────────────── WHAT I ACTUALLY BUILD → Production AI agents (single + multi-agent orchestration) → MCP servers and clients — custom tool integrations for any API → Agent security: sandboxing, key isolation, action approval, human-in-the-loop → RAG systems with hybrid retrieval (vector + BM25 + reranker) → Voice agents, customer support agents, autonomous commerce agents → LLM evals, tracing, red-teaming, and prod observability → Web3 ↔ AI bridges (agents that transact on-chain safely) STACK Python, TypeScript, LangGraph, CrewAI, Pydantic AI, MCP, OpenAI / Anthropic / local LLMs (Llama, Qwen), Pinecone, Weaviate, pgvector, LangFuse, Braintrust, Solidity, viem, Foundry. ────────────────────────────────── WHO I WORK WITH Funded founders and serious teams shipping real agent products to real users. If you need a chatbot demo, I'm not your guy. If you need someone who can architect, code, ship, and harden a production agent — let's talk. NEXT STEP Send me 2–3 sentences on what you're building and where you're stuck. I'll tell you within 24 hours whether I'm the right fit.
