I’ve been working in Web3 directly for almost two years now, but I've been learning and have been invested in BTC, ETH & SOL since 2016 as well as with various other altcoins and projects along the way. I have learned a lot and I keep learning!
Most recently I've been leading and running MetaVersus.World is a hyper-realistic virtual gaming multiverse in the Metaverse, built using Unreal Engine 5 on the BSC EVM Blockchain complete with NFT marketplace and Metaverse-as-a-Service tooling for brands, the platform fuses the worlds of traditional gaming and ecommerce with Web3 technology to provide hyper-realistic, engaging and immersive metaverse environments. Unfortunately our primary backer was unable to fulfil their funding commitments so we've had to unwind the company. However, I LOVE this space, it's the future and I enjoy living and breathing it.
As COO then CEO, a large part of my role was outreach and talking to partners, brands, launchpads, platforms, marketing/representing the company at conferences, speaking on panels, conducting AMA's, managing relationships and staying up to date with the tech, projects, products and the industry in general. All the teams from UE front end, blockchain, UI/UX, Sales, BizOps, Marketing etc…all reported to me and I had the ultimate say on direction. I understand the business, blockchain, infrastructure, architecture, NFT’s, DAO’s, communities, marketplaces, DeFi, DEX’s, CEX’s, Market Makers, KOL’s….I’ve been involved in every aspect. In crypto, you need to be agile, fast, hungry, adaptable, hungry, humble, responsive, and have a can-do attitude.
Prior to this role, for 20 years I have been helping companies understand, ideate, build, deliver and scale cutting edge digital experiences, customer journeys and modernize/innovate through new technology adoption. What started as building apps back almost 15 years ago, quickly turned into digital transformation, helping companies transform to enable & empower themselves as mobile optimization became table stakes and Agile methodologies, philosophies and culture also became standard. I am intimately familiar with software development and technology.
Today we find ourselves back at the advent of a new technology era, Web3, AI, Blockchain, Crypto...It's 100% the future, and mainstream adoption is starting - but we’re still early, and that’s exciting. I have been through the adoption curve before, from early exploration to mass adoption, because of this I bring a wealth of experience. I have progressed from sales, to sales leadership to C-level exec, working with and for fortune 500 companies as well as scaling startups and leading cross-functional teams. I have a particular knack of explaining complex technical scenarios into simple terms, enabling business leaders to execute and deliver against their goals, achieve high growth and exceed expectations.
I have been specialized in blockchain development for 5 years and have experience in full stack web development for 8 years.
I love challenges and very sensitive to new techs

My blockchain development, DAO, DeFi, civic government, and writing experiences have primed me to be a valuable contributor to back-end dApp development in the EVM ecosystem. I am looking to advance the decentralized coordination movement with a public goods focus. I am a most passionate advocate for new ways of human coordination.
For five years I worked in mechanical engineering, but it was too equipment-based. I learned I needed more human-focused work. I taught myself writing and have been nominated by a film festival for a screenplay. I've worked in film and live events and was a city plan review supervisor, where I found my passion for human coordination. With my diverse background, I have a very unique, versatile, and holistic perspective that is valuable to every rung of the ladder.
I have since taught myself blockchain development with a focus on the Solidity/Hardhat/Ethers.js/Mocha/Chai/Javascript/React/Next.js/Node.js stack. I have now deployed two MVP projects to testnets: a Universal Basic Information Dashboard system for DAOs and cities, as well as an automated payroll app. As a third portfolio project, I am currently working on a NFT system contract that manages fan gating, interaction, and release specifics for an upcoming creative series.
I think it is an absolute travesty that NFTs and the like have to this point been mainly used for speculation or as in-crowd profile pic bragging. There needs to be far fewer humans working on financial and meme blockchain products and many more working on governance, coordination, and novel mechanisms we can't even think of right now. I aim to be a part of the latter.
After I met the onchain universe, I saw clearly where my path and what my objectives needs to be. Clearly the UX architecture is one of the main foundations for a good contract and a human understanding in the face of economic complexities like we have in blockchain.
I'm Fascinating that we are using Smart Contracts right now, the first step to make our profession on the hierarchy that deserves, designing and thinking about protocols...this is the way.
I started investing in defi protocols, after months seeing how huge it was, I analyzed, used and really enjoyed the application of my area (UX, UI) in this meta/universe.
Soon after, I looked for a chain in which it was "new" and had good foundations, which was the Fantom network, where I participate in a large community, in which I found many professionals related to me.
In this period, I had the opportunity to work for major network protocols, I went to work for Tomb Finance, FTMpad, SpiritSwap, and NFTs among others that I have in my portfolio.
But I will certainly seek to study good references in UX knowledge in all types of protocols. Cosmos, Fantom, Solana, Avax, various EVMs, I really enjoy them all.
Have a great day!
In 2022, I started my career as a freelance Blockchain engineer: I developed multiple DApps both in the DeFi space and NFT space.
Before joining the crypto space, as a security consultant for 4 years, I conducted several Penetration Testing and Source Code Review activities. Then I started training in classes aimed at developers to teach secure code methodologies.
I started my career as Web Developer, developing web apps for private companies and national agencies.

While working as a senior software engineer at Kofax Inc., I started reading books on Bitcoin and Blockchain in 2017. Fascinated about the underlying mathematics, game theory and technology, I started building a relay-friendly EVM sidechain consensus for Nexty, a multi-protocol Wallet app and browser extension (ezDeFi/LZ), multiple DeFi applications and a DEX Aggregator with Smart Order Routing for LaunchZone.
Since the beginning of 2021, I have been researching and designing a synthetic protocol that can naturally handle asset under-collateralization. After working on different fields of blockchain tech, including DeFi applications, DEX aggregator, infrastructure, and on-chain data analytics, I notice the increasing market demand for perpetual futures DEX and decide to launch Derivable as the first of its kind.
I have over 2 years of experience in creating multiple apps in Solidity, and as a Consensys certified Ethereum developer I am very familiar with blockchain concepts, Ethereum, the EVM, and smart contract security best practices.
I started as an Android software developer in 2014 and had a few iOS side projects during the years. In 2018 I partially switch to web frontend development in VueJS and in the next year I replaced native android with Flutter framework. I had several projects during the years as developer, senior developer and leader of a small group (2-4 people).
I have multiple years of web app development experience with VueJS 2 and 3 with composition API and Server Side Rendering too. Regarding the mobile apps, my focus is primarily on Flutter in the past years. I created real-time, area based (walkie-talkie like) communication app with native plugins, several custom built webshops(some of them has hundreds of thousands of customer), landing pages, global "business management" tools, social networking apps etc. I also have experience of creating NodeJS backends in TypeScript with TypeORM.
I've started using solidity a few month ago and currently working on my own project.
Tech stack:
- frontend: Vue3, ethers.js
-backend:
- NodeJs, ExpressJs, TypeORM
- EVM
