I have helped to launch 20+ projects, that have raised more than $120M in capital using my services. These projects have listed on nearly every major exchange in the world and totaled more than $10B in combined peak market cap - fully verifiable on Coinmarketcap. Welcome to the 2026 bull market! In today's market, projects are raising millions through token sales. Please see my case study below, where my client raised over $19M and listed on Binance and Coinbase. Over the past 6 years, I have worked tirelessly and continuously to deliver 300+ whitepapers, decks, and token economics models for the top projects in the space. Launch your project using my token sale package below or pick from any of the items to fit your needs: - Whitepaper Writing (Token Sale, IDO, Gitbook, Whitepapers) - Token Economics (valuations, ecosystem viability, token sale, caps, distributions) - Investor Presentation Deck (blockchain and crypto VCs, whales, and general token buyers) - One-pager (high level summary and token sale information in a single page) - Website (project landing page, marketing copy, web3 design) - Custom Product Design (web3 and mobile apps, dashboards, pre-sale pages, etc) If you are looking for a complete package to perform a token sale (sometimes called an ICO), you have come to the right place. I have lectured at the University of California, consulted for professors, contributed to leading academic research, advised corporations, executives, CEOs, and have enjoyed one-on-one dialog with several Top 20 cryptocurrency founders. I am also an inventor (U.S. patented) of a blockchain-based TRNG and mechanism for blockchain-based provably-fair gameplay. Former contributing author to Forbes and CoinTelegraph, have been cited by Inc. Magazine and Fortune, and have consulted for over (20) blockchain and token-based Initial DEX Offerings (IDO), Initial Exchange Offerings (IEO), and Initial Coin Offerings (ICO) and am an advisor to (4) companies, one of which is publicly-traded. I have been interviewed by numerous publications, been on the front cover of four globally circulated magazines, and have public-profiles in leading industry websites such as Crunchbase and AngelList. Below is a list of my experience and expertise: - Token sale via IDO and launchpad, IEO, STO and formerly ICO - AI (AI Agents, Large Language Models, Generative Pretrained Transformers, Tagging and Training, etc.) - Memecoins and Platforms (Pump.fun, Decentralized launches) - DePIN (decentralized network hardware and IOT integration with custom blockchain and token economy) - NFTs (Metaverse, Collection Minting and Launch, Chainlink VRF, GameFi, P2E, Land, ERC-721, ERC-1155, Solana, Polygon, Opensea, etc) - DeFi Consulting (swaps, liquidity pools, borrowing and lending, yield farming, impermanent loss, governance tokens) - AMM DEXs (Liquidity, PancakeSwap, Uniswap, Curve, Balancer, SushiSwap, etc) - SSI and identity solutions, attestation and verification - Listings on exchanges, launchpads and Coinmarketcap - Investment terms, valuation, lockups, cliffs, vesting, distribution, circulating supply, etc. - Market making - bid/ask spread, depth, volume, strategy - Bot protection - protect against snipers, MEV bots, sandwich trades, front-running, mempool sniffing, etc. - TGE, initial and fully diluted valulations - Marketplaces and ecosystems - Token standards (ERC, BEP, SPL, etc.) I co-founded and currently operate a 70-person software and blockchain development company, and was formerly a VP at a global investment bank. As such I have a solid background in software and in finance. You will not find someone with more credibility and public-validation with a proven track record of success both here on Upwork and outside. Please send me an invitation so we can discuss your project further.
