Experienced Blockchain and AI Expert

Hello, my name is Ira Miller. I have been developing Bitcoin and blockchain software since 2011. I built some of the first ever Bitcoin payment plugins, as well as the second ever payment processor (Coinapult). You can search "Ira Miller Bitcoin" in google and find a long history of my activities. I've developed blockchains from scratch, and many tokens using different protocols on both the Bitcoin and Ethereum blockchains. I can also develop for Solana, Binance, Polkadot, and other major chains. I am a super talented, speedy developer who excels at translating complex business requirements into production-ready solutions. In addition to my deep blockchain expertise, I am an expert in building production-grade agentic AI systems designed for scalability and autonomy. My development focus leverages a powerful, cohesive stack (Python, LangChain, LangGraph, Vector DBs) to move beyond simple chat interfaces and create true intelligent software. I have successfully transformed complex enterprise needs—from investigative data correlation and administrative workflow automation to critical financial analysis and sophisticated security analysis—into high-velocity, autonomous solutions that deliver measurable results directly into client operations. I have extensive experience in both the heavy lifting of software architecture and writing, as well as managing. I was Director of Engineering at BitInstant, one of the first Bitcoin onramps, back in 2011. I was CTO then CEO at Coinapult, one of the first Bitcoin web wallets and payment processors. I've since held similar positions at a variety of projects that fit my passion. I've developed about every type of project possible using web3 tech from cryptographic libraries, wallets and plugins to digital ID, gaming and NFTs. Whatever your needs are, I have technical experience in that area. Technical Expertise: Blockchain & Web3: - Bitcoin, Ethereum, Solana, Binance, Polkadot, and other major blockchains - Smart contracts (ERC-20, ERC-721, ERC-1155, Solidity, Rust) - Wallet development (hot/cold wallets, hardware integration, cross-platform native, web wallets) - Payment processors and plugins - Cryptographic libraries and security systems - DeFi protocols, Layer 2 solutions, cross-chain interoperability - IPFS and decentralized storage AI & Agent Development: - Production-grade AI agent orchestration using LangChain and LangGraph - Multi-step reasoning and decision-making workflows - Vector database integration for data grounding and retrieval - Autonomous agent systems for financial analysis, security analysis, and workflow automation - Python-based AI development stack Programming Languages & Frameworks: - Python (expert level - for both blockchain and AI development) - JavaScript (browser and server - expert level) - React, Next.js - PHP (Laravel) - extensive historical experience - Solidity, Rust, C, C++ - API development and integration (hundreds implemented over decades) I maintain an active interest in market and technical developments in both the crypto sector and AI space. I have broad and deep knowledge about all current events and trending topics. I hold crypto personally and advise other investment groups. I have written well over a dozen whitepapers, and edited hundreds for friends and colleagues. I have a strong math background, and have developed a number of cryptographic systems from scratch. If security is your focus, I'm your developer. I am bilingual in English and Spanish, also splitting my time between the US and Panama. Finally, I have quite a bit of experience as a founder, CTO, CEO, and managing technical and mixed teams, should that be required. I've successfully launched startups, gotten them funded through NY VCs, etc. Whether you need blockchain development, AI agent systems, or a combination of both, I bring production-level expertise, speed, and a track record of delivering high-impact solutions.
