    Hi! Upwork uses my first name, Royce, but I go by Aaron (my middle name). I am a quantitative /systematic trader that also helps others with all things related to running algorithmic trading systems. This includes tasks such as system modeling/backtesting, data collection/storing, signal processing based on technical indicators, portfolio and position risk management, etc. I am a skilled programmer that writes well documented and organized code that is easy to follow and build upon. I provide even more value with my trading knowledge and experience. I've contributed to hundreds of successful projects to date, and look forward to taking on many more. Some of my specialties includes using QuantConnect (where I am a recommended consultant), Interactive Brokers API integration, TradeStation, and TradingView. I've learned a lot about technical analysis going through the Chartered Market Technician (CMT) program where I've passed all three of the exams on my first try. I'm currently working on becoming a chartered member. My past and current clients include investment/financial advisors, portfolio managers, CTAs, and professional traders. I also work with individuals that are just getting started in trading. Check out the testimonal below to see what an active client who manages around 150M+ AUM had to say about working with me. If you are interested in learning how to write algorithms for QuantConnect, I've created a training course of 22 different algorithms that I explain in 27 videos, almost 17.5 hours of instruction. Message me if you are interested, and I can send you more information.

These projects have totaled more than $8B in combined peak market cap - fully verifiable on Coinmarketcap.com. Welcome to the 2024 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, respectively. 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) 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 three 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 (Large Language Models, Generative Pretrained Transformers, Tagging and Training, etc.) - 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 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.

    I was working as an IT expert in electronic trading for several years at Swiss Banks. Afterward, I founded my own international IT business, providing consulting and developing services to business clients from several branches, including Insurance companies, real estate agencies, newspapers and so on. Always strong interested in helping and informing people about IT, I was writing a weekly newspaper column for a German newspaper for 7 years, to bring useful IT knowledge to everybody. As my business was growing year to year, my work changed from being an IT professional to being a CEO, taking care of employees, holding meetings and creating strategies. Being a born problem solver, I started missing live out on my passion more and more. I learned programming by myself at the age of 11 and built my first website. Since then, I kept learning new programming languages and technologies to further solve real-world problems and make life easier for everyone. This is what I want to do, and this is what I am doing 😊 I would love to work together on interesting and exciting projects, solve your problems, setting focus always on the highest quality possible. It always pays out solving a problem in the best and smartest way, it is my obsession to find and realize it for you. What you will get if we are working together: ✅ Real IT Expert with 20 years of experience in the business. ✅ 25 years of experience in programming (yes, I started programming before being old enough working as an IT professional 😊). ✅ Working as a System Engineer, IT Consultant, Developer and Trading Expert, I have a deep understanding of IT and business needs and an open-minded view, seeing the whole infrastructure instead of just “my box”. ✅ Experience with international businesses, knowing very well business standards. ✅ Experience in working as an employee as well as being an entrepreneur, knowing the needs and expectations of both sides. ✅ More than 15 years of experience in finance and banking. ✅ 8 years of experience in the crypto space. ✅ Clean, well-documented and easily readable code. ✅ A solution focused on quality. It is not only my job, it is my passion to solve your problem for you 😊

    I am an digital marketer with 5 years of experience in the digital content industry. I work with Search Engine Marketing and Traffic Acquisition: SEO, PPC (Google Ads), and Content Marketing (content and blog strategy). Along my journey, I had the luck to build a rich background of hands-on experience across many websites and industries, from SaaS companies to large ecommerce websites. I have established procedures for building whole SEO campaigns and managing specific projects related to website audits, content marketing, and link building/off-page SEO. My work involves: - Website Audit and identifying quick-wins SEO opportunities - Building a data-driven and user-driven content strategy - Keyword Research and Keyword Maps - On-page optimization - Technical optimizations (speed, performance, images, crawlability, indexing, canonicals, international targeting, interlinking, and more) - Off-page campaigns (link building, digital PR, social media promotion) - Project management (managing and collaborating with copywriters, prospectors, and outreach specialists) - Advising CRO and Paid Advertising strategies to couple with SEO and content marketing I’m a true team player, always open to discussing the project, the company, and our goals. I value good professional communication, and I know how to give and take feedback. Collaborating with me will prove to be a seamless experience. What sets me aside is my ability to merge creative and analytical skills. I understand SEO as a heuristic approach to managing a website and delivering valuable content to the target users. Being data-driven, problem-solving, and thinking out of the box are essential for that. As a creative professional, I have experience in copywriting and content creation. As an analyst, I am proficient in auditing websites, identifying SEO opportunities, and creating content strategies driven by results. I know how to leverage every single piece of data reported on Google Search Console, and I am an advanced user of Google Analytics. I have my own paid access to SEMrush and Ubersuggest, so I have all the data and tools we’ll need to boost your website rankings. I can work with WordPress, Wix, Shopify, and most CMS available today. I’m familiar with code, distinguishing optimization opportunities directly in the source code and editing HTML, CSS, PHP and Liquid scripts if needed. I know how to leverage Google Sheets formulae to build comprehensive, visually pleasant, and fully automated spreadsheets. I have intermediate level in Python, which helps me automating important parts of my work to improve my productivity, accuracy in data analysis and assertivity in decision making processes. Feel free to contact me for further information or to schedule a meeting via Upwork. I’m looking forward to your invitation!

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. She works very diligently to make sure the tasks assigned are submitted on-time. 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! Contact me to discuss the details.
