These projects have totaled more than $8B in combined peak market cap - fully verifiable on Coinmarketcap.com. Welcome to the 2025 bull market! In today's market, projects are raising millions through token sales. Please see my case study below, where my clients raised nearly $8M and $9M in Q1'2024 and another successful launch in Q4'2024.

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.

I bring a diverse set of skills to manage nearly any IT problem. I don't claim to know everything, but I've always been tenacious and I won't stop until I figure it out. Hiring a developer can be a gamble sometimes if you're not careful - low-cost developers entice potential clients with low budgets and promising they can do anything. What they're after is just the job, not necessarily making your project succeed. If a freelancer charges a low rate and seems to have plenty of time available, there's probably a reason. A good freelancer will be upfront if something is outside of their skillset or if they can't fit the project in their schedule, and is careful not to overpromise. Wasting a client's time and money to deliver low-quality results isn't a sustainable business. If your project uses some technology I'm unfamiliar with, I generally don't charge for the time spent educating myself on it. I like learning new things, and it may be useful to know in the future. Whether you need a brand new application, bugfixing/refactoring a legacy codebase, website/CMS management, Linux/Windows server administration, or anything else involving software, check out my profile details and my portfolio of work to see if I might be a good addition to your project! [NOTICES] - I am happy to sign an NDA for your project if required! - I'm a native English speaker, if you consider what the southern states speak to be English 😅

    Running an IEO or a blockchain-related service? Need qualified content for your blog or any other online media to increase your expertise and boost visits to your website? You’ve come to the right place! I have solid experience in blockchain and cryptocurrencies as I communicate with traders and industry leaders and constantly monitor the crypto market trends. I believe this technology can potentially revolutionize many areas of our lives. I was one of those who purchased Ether for 15 USD. I can explain the difference between DPoS and LPoS to a 5... no, at least 10-year-old child. Here’s my achievement list: - working in the IT area since 2008 - writing articles since 2013 - helping blockchain and cryptocurrency projects since 2017 (oh, this magical bullrun!) - 1,500+ articles written in total for different projects I love writing about complex technologies and explaining them in simple words. My texts are 100% original, lively, error-free, SEO-friendly (if needed), and easy to comprehend. Besides, when mentioning some facts I always add proof links to reputable resources. Finally, to keep readers entertained, I add some spicy words and numerous idioms. I've been working in such companies as ByBit.com, Nomics.com (now sadly closed), Cryptopay.me, TokenGuard, BestRate.org, and CryptoHeroes. Also, for some projects, I wrote articles as a shadow-writer to be posted on Cointelegraph. --- Here's what my clients say about my work: "Kate has been the best freelancer I've collaborated with. Her work is always well-researched, high quality, and delivered on time. What's more, she is very communicative, asks questions to ensure she meets expectations, and adapts well to succeed in different tasks. I would highly recommend Kate to anyone who needs a talented and professional writer." - Alice Leetham, BanklessTimes "Kate is very open for communication and feedback.

I would definitely recommend Kate to work on your next project." - Racheal Koh, ByBit "Kate is dedicated and goes the extra way to help understand difficult concepts. I have worked with many people here but there is no one better than Kate. I highly recommend her to anyone on upwork." - Timothy Westlake, cryptocurrency investor --- Need some qualified content for your crypto project? I'd be happy to help!
