Hire the Best Distributed Computing Specialists in Hanoi, VN

I help businesses deploy secure AI Agent infrastructure, optimize token budgets, and build transparent blockchain supply chains. As a CISSP-certified security engineer with 10+ years of infrastructure experience at enterprise scale (VNPT), I bridge the gap between advanced AI capabilities and strict production security. Here is how I can help your team: ⚡ AI Operations & Eliza OS Integration - Custom Web3 AI Agents: Build modular action plugins for Eliza OS (ai16z framework) using Node.js/TypeScript and Viem. - Enterprise LLM Gateways: Deploy and scale LiteLLM gateways on VPS (Oracle/AWS/Hetzner) with automatic API key rotation, budget capping, and multi-model failover. - Workflow Automation: Design resilient n8n and Make workflows integrated with Claude/Gemini API, database layers, and Telegram CRM bots. 🔒 AI Security & Governance (ISO 42001) - Prompt Firewalls: Implement runtime guardrails to prevent Prompt Injection, Jailbreaking, and sensitive data leakage (PII redaction) through LLM gateways. - Compliance Audits: Perform gap assessments for the EU AI Act, NIST AI RMF, and ISO 42001 standards, translating complex regulations into actionable technical checklists. ⛓️ Enterprise Blockchain & Traceability - Private/Consortium Networks: Setup and optimize Hyperledger Besu consortium nodes (QBFT consensus) for cost-free enterprise logging. - Gas Optimization: Implement dynamic EIP-1559 gas estimation and transaction batching (TraceBatch) on Polygon L2, achieving gas costs below $0.005 per record. - GS1 EPCIS compliance: Map complex supply chain events (nông sản, logistics) into standard decentralized schemas on IPFS. Why work with me: • CISSP Certified (International standard for cybersecurity professionals) • Master of Engineering in Information Security • Hands-on production experience in both Web3 (Solidity, Besu) and AI (OpenClaw, Eliza OS) • Python & TypeScript developer — I code and deploy what I architect • Async-first communication with detailed technical memos and video updates Recent results: • Scaled a LiteLLM dual-instance failover gateway for a business automation portal. • Reduced Polygon L2 gas costs by 60% for a traceability app using Viem dynamic pricing. • Built an automated AI Content Factory pipeline using Playwright headless browsers and cookie session synchronization. Let's discuss how we can secure and automate your system. Send me a message, and I can analyze your architecture requirements today.
