Dharmendra Singh B.

Over the past 21+ years I have worked across early web systems, enterprise software, blockchain platforms, and AI. These days I spend most of my time helping founders and product teams figure out what they actually need to build, and then building it with them. I enjoy making complex technology feel straightforward. That is something clients come back for. I have spent 11+ years deep in blockchain and the last few fully focused on AI. I can connect those two worlds in ways most developers cannot. Clients tell me they appreciate that I do not just execute tasks. I ask questions, flag things that have not been considered yet, and keep the bigger picture in view throughout the project. 🤖 ARTIFICIAL INTELLIGENCE AND GENERATIVE AI • AI Agents and Multi-Agent Systems using LangGraph, CrewAI, and AutoGen for task automation, research, and business process orchestration • RAG pipelines and enterprise knowledge platforms using Pinecone, Weaviate, Qdrant, and ChromaDB • LLM integration across OpenAI, Claude, Gemini, and open-source models into real business workflows • MCP, prompt engineering, context management, and agentic workflow architecture • AI-powered trading platforms with ML signal generation, backtesting, risk management, and live execution • NLP, sentiment analysis, OCR, document intelligence, and intelligent workflow automation • Computer Vision for object detection, video analytics, behavioral analysis, and real-time event detection • Model deployment, inference optimization, evaluation frameworks, and production AI infrastructure • Backend systems for AI using FastAPI, Flask, Django, GoLang, and Rust 🔗 BLOCKCHAIN AND WEB3 • 11+ years across Ethereum, Solana, Polygon, BSC, Tron, Flow, Hyperledger Fabric, Stellar, TON, Bittensor, and Aptos • End-to-end Web3 platforms including DeFi protocols, NFT marketplaces, custodial and non-custodial wallets, DEXs, and dApps • Smart contracts in Solidity, Rust, and Cadence covering ERC-20, ERC-721, ERC-1155, security reviews, and audits • Token launches including ICO, IDO, and IEO ecosystems, tokenomics design, and exchange integrations • Whitepapers, governance models, and go-to-market strategy for public, private, and consortium networks • Layer 2 scaling, cross-chain bridges, and gas optimization • Full project lifecycle from architecture and security design through to production delivery 📊 PROJECT HIGHLIGHTS • Built a multi-agent RAG system for an enterprise client processing 1M+ internal documents, reducing research time by 70 percent • Delivered an LLM-powered support agent using OpenAI and LangGraph handling 10,000+ queries per month with over 90 percent deflection rate • Architected an AI algorithmic trading platform with ML signal generation and live multi-exchange execution • Built an automated crypto trading bot running across Binance, Bybit, and OKX with real-time risk management • Designed and deployed a DeFi lending protocol on Ethereum with 5M+ TVL including liquidation engine and governance • Delivered a supply chain traceability platform on Hyperledger Fabric tracking 500,000+ assets annually • Led end-to-end delivery of multiple NFT marketplace platforms with minting, auction, royalty, and secondary market features • Built a real-time Computer Vision productivity monitoring system deployed across 500+ workstations • Delivered an OCR and NLP document processing pipeline that reduced manual data entry by 85 percent for an insurance client 🏢 INDUSTRIES SERVED FinTech and Trading | DeFi and Crypto | Enterprise SaaS | Healthcare and MedTech | Supply Chain | Real Estate | E-Commerce | Legal and Compliance | Media Platforms 🤝 HOW I WORK • I ask a lot of questions upfront, not to slow things down, but because the right questions save weeks later • I am easy to talk to, even on technical topics. Non-technical founders tell me I make things click for them • You will always know where the project stands. I do not go quiet and reappear with a finished build • I have worked with clients across the US, Europe, the Middle East, and Asia. Async communication is second nature to me ⚙️ CORE TECH STACK AI and ML: Python, LangChain, LangGraph, CrewAI, AutoGen, OpenAI, Claude, Gemini, HuggingFace, Pinecone, Weaviate, Qdrant, ChromaDB, FastAPI, Flask, Django Blockchain: Solidity, Rust, Cadence, Web3.js, Ethers.js, Hardhat, Foundry, Anchor, Truffle Backend and Infrastructure: GoLang, Node.js, .NET, Docker, Kubernetes, AWS, GCP, Azure Frontend: React, Next.js, TypeScript 🗣️ If you are not sure exactly what you need yet, that is fine.
