Want to turn complex blockchain tech into high-converting content that drives token presale hype, community trust, and organic traffic? Most Web3 projects struggle to strike the right balance: their content is either too dry and overly technical, or it sounds like low-effort, robotic AI hype. I write authoritative, deeply researched articles that bridge this gap. Whether you need to build immediate FOMO for an upcoming launch or humanise your brand to create long-term loyalty, I deliver copy that converts. The specialised Web3 articles I write for your brand: 🔥 High-Converting Presale Articles: High-impact promotional content, crypto media guest posts, and launch announcements designed to explain your tokenomics clearly, validate your utility, and drive investor action during seed and public rounds. 🧠 Humanising & Thought Leadership Articles: Deep-dive founder stories, "Build-in-Public" logs, and relatable case studies that break down complex tech into empathetic, human narratives to forge deep trust with your community. 📈 SEO-Optimized Deep Dives & Blogs: Thoroughly researched, long-form content covering L1/L2 protocols, DeFi strategies, DePIN networks, and Web3 gaming—optimized to rank on search engines and attract consistent organic traffic. 📄 Technical Whitepapers & Litepapers: Structuring your project’s core technical value, roadmap, and token ecosystem into professional, investor-ready documentation. Why top blockchain brands work with me: - Zero Hand-Holding: You do not need to explain smart contracts, liquidity pools, or zero-knowledge proofs to me. I live and breathe Web3. - 100% Job Success Score (JSS): A proven Upwork track record of pristine client satisfaction and on-time delivery. - Data-Driven Results: I write for human engagement while ensuring optimal formatting for readability and conversion.

I build production-ready AI systems that automate real workflows, integrate with existing infrastructure, and scale reliably. I’m not just an AI developer — I’m a hands-on systems architect who designs and builds complete solutions end-to-end. From AI agents and LLM-powered applications to backend infrastructure and deployment, I focus on delivering systems that actually work in real environments. No prototypes. No over-engineering. Just clean, scalable, high-impact AI systems. 🔥 What I Specialize In (AI / ML) I design and build practical AI systems that solve real business problems: • AI Agents (autonomous workflows, task execution) • LLM Applications (GPT-based systems, copilots, assistants) • Retrieval-Augmented Generation (RAG) systems • AI Automation for business operations • Multi-agent systems & orchestration • AI-powered dashboards & decision tools • Data extraction & document processing (PDFs, structured/unstructured data) • AI chatbots & conversational systems • AI integrations with APIs, databases, and SaaS tools • Vector databases & semantic search systems ⚙️ AI Systems I Build • AI SaaS platforms • Internal AI copilots for teams • Customer support automation systems • AI-driven workflow automation tools • Knowledge base AI (RAG systems) • Intelligent alerting & monitoring systems • End-to-end AI infrastructure ⛓ Advanced: AI + Blockchain Systems For complex use cases, I combine AI with blockchain: • AI agents interacting with smart contracts • AI-powered blockchain analytics • On-chain automation workflows • Tokenized AI ecosystems • Wallet-connected AI systems I’ve led development of Ayni.Gold, a live real-world asset tokenization platform with full infrastructure including smart contracts, staking, investor dashboards, and backend systems. 🧠 Backend & Infrastructure Strong focus on scalability, performance, and clean architecture: • Python, Node.js, TypeScript • FastAPI, Express.js • React / Next.js • PostgreSQL, MongoDB, Redis • Vector DBs (FAISS, Pinecone, Weaviate) • WebSockets & real-time systems • Docker & AWS deployment • CI/CD pipelines & cloud infrastructure 🚀 How I Work Clients work with me because I deliver: • Fast execution (MVPs that go live quickly) • Clean, scalable architecture • Direct communication (no middle layers) • Strong technical decision-making • Reliable, production-ready systems I think like a technical founder, not just a freelancer. 💡 What You Can Expect • Clear architecture before development • Efficient and maintainable code • Scalable AI systems (not quick hacks) • Honest timelines and communication • Solutions aligned with real business goals 📩 Let’s Build If you’re looking to build: • AI agents or automation systems • LLM-powered applications • AI SaaS products • RAG-based knowledge systems • AI-integrated platforms • Or scalable backend systems Send me your idea, timeline, and requirements. I’ll propose the fastest and most practical way to build it.

96.8% retrieval accuracy. 150-page contracts processed in under 60 seconds. Zero cross-tenant data leakage. I build RAG and AI systems that survive real production, not just demos, and clients keep hiring me back to build the next one. I'm Top Rated Plus, with 3+ years building AI systems and 7+ years in full-stack engineering. A lot of my work is repeat business. One client has brought me back 5+ times, because the systems hold up after launch, when real users and messy data arrive. RAG and document intelligence are my deep end, but I build complete production systems end to end: SaaS platforms, automations, and full-stack MVPs. The same discipline that keeps a RAG system reliable keeps the simpler builds clean, which is why teams trust me with both. RECENT WORK DocsFlow | Document Intelligence Platform 96.8% retrieval accuracy Hybrid search with source-linked, citation-backed answers 150-page documents processed in under 60 seconds, down from 3 to 5 minutes Four-layer tenant isolation with zero cross-tenant data leakage Around 85% AI cost reduction through model routing and caching SureCiteAI / LPA Analyzer | Legal & Contract Intelligence RAG across thousands of documents with grounded, citation-validated outputs Deterministic validation layer so financial figures are never generated by the LLM Built for legal and compliance-sensitive workflows LeadFlow AI | Multi-Agent Operations Platform AI-powered qualification, routing, and follow-up Integrated across Supabase, WhatsApp, APIs, and n8n Reduced manual operational effort by 40 to 70% (Also: multi-agent game-dev systems and real-time computer vision for fitness. Happy to share.) WHY TEAMS HIRE ME A cheaper freelancer can usually get an MVP working. The problems show up later, when real users, messy data, scaling, edge cases, security, and AI cost all arrive at once. That is exactly when architecture starts to matter, and when getting it wrong gets expensive. I'm more senior and product-minded than a typical freelancer, but more hands-on and cost-effective than an agency or an early senior hire. In practice: fewer wrong turns, faster decisions, and a system built right from day one. TECHNOLOGIES Next.js, TypeScript, Python, PostgreSQL, Supabase, Pinecone, pgvector, OpenAI, Claude, Gemini, Llama, LangGraph, CrewAI, Stripe, Vercel, AWS. Microsoft, Google, and IBM AI certified. SPEAKING TechStars Startup Week, DeFi Summit London, LevelUP KL Tell me what you're building and the outcome you need. If it has to actually work in production, that's where I'm strongest.

I'm an experienced PR writer in the Web3, Fintech & politics space, having served as the Head of Content for NFT Plazas, Content Manager at STORM Partners, a blockchain Solutions Provider in Switzerland, and Guava Studio, a UK-based PR & marketing firm. I write thought leadership & organic content for crypto media outlets, like Forbes, Cointelegraph, DailyCoin, and FX Empire. I'm adept at writing organic interview-style articles, research pieces, opinion articles, reviews & educational content that get published on their own merit. I'm also adept at reaching out to and working with editors and journalists to secure publication. I understand their requirements and needs and write with this in mind. I'm also an accomplished SEO and GEO marketer with knowledge of AH ref & SE Ranking. How I use AI I'm comfortable not using AI if it is requested - although this will take more time (like the good old days) If using AI, all content is my own; I do not ask AI to create content for me. However, I may use AI to help rewrite and summarise. I will then go in and reword in my own voice. I use AI to speed up the process, improve efficiency, and enhance quality. I have a degree in Politics & Social Policy.
