Hey, nice seeing you here! Here's some of my story:
# Currently
I've been developing NFT products for Big Head Club, a company founded by Mack Flavelle. Worked as a Full-stack Developer, but mostly dealing in the web2 side of things (front-end, serverless functions, databases if needed), while interacting with smart contracts through libraries such as ethers.js, wagmi and providers such as Alchemy and Infura. Did contribute code reviews, architectural considerations and a little code to the Solidity side of things though.
# In the past
I've been a Full-stack Developer in, and eventually lead of, a compact and efficient team at a SaaS company which serves Brazil's biggest franchises, such as Burger King and Stone. I've helped the company more than double its MRR two years in a row, spearheading development of chat systems, ticketing systems, checklist and data visualization apps, all while mentoring junior developers, implementing CI/CD automation and creating reliable cloud infrastructure.
I am a Web3 Product Manager with experience in blockchain and smart contract development. My expertise lies in DeFi smart contracts and NFT development. I have a deep understanding of blockchain fundamentals such as smart contracts, Web3, and DAOs, and I am knowledgeable about decentralized exchanges and other DeFi protocols. I have developed applications on the Ethereum and Solana blockchains as well as Polygon layer 2 side-chains. I have created, compiled, tested, and debugged smart contracts using Solidity, Rust, and JavaScript languages. I also have experience with full-stack development using various languages and web frameworks, including JavaScript, Flask, PHP, React/Express/Node.js, MYSQL/MongoDB, Serverless/Lambda, S3, EC2, Cloud9, and SAM CLI development on AWS Cloud. I have worked collaboratively in cross-functional teams to build web3 platforms with a focus on IT modernization and digital transformation.
I graduated CUM Laude with an average mark of 9.27 during my university career. Due to my performance, the university awarded me with the 2021 Academic Excellence Bursary, which is only given to the best student of the year. I have 2 years of experience as an Analyst/Programmer. As an Analyst I am able to write quality functional specifications based on user requirements. As a Programmer I can translate functional specifications into code with surprising ease, delivering quality programs and meeting deadlines on time.
Dynamic and creative software developer with over 5 years of experience in producing robust code for high-volume companies. Eager to support the dev team at Sharetempus Inc. with top-notch coding skills. In previous roles, doubled code-efficiency of Consensus Base Inc.,
Deep understand of POS vs POW and Dapp development experience. While working on the Dapp development, developed smart contracts using Solidity & Rust.
For Dapp and Smart contract development and audit, I have used Web3, Solidity, Hardhat, Infura, Truffle, MIST/Remix.
Deep understanding of the Defi-EcoSystem and its sub-services (Lending Pools, AMMs, Assets Managements)

I'm on the younger side when it comes to professional developer experience, but my native fluency of the space, coachability, and learning speed put me a cut above the rest. I established a Blockchain youth organisation where I served as an instructor for Web3 development and solidity smart contracts. I've also worked as a De-Fi portfolio manager at a family office fund, not for disclosure. I'm ready to start formally building the future of De-Fi!
And speaking of build, here's my stack!
- Solidity
- Truffle/Hardhat
- The Graph
- Remix + Debugger
- Slither Static Analysis
- Basic AMM Algorithms
- NextJS/React
- CSS + Tailwind
- Alchemy/Infura/Moralis
- NodeJS (context: Unit testing)
Self taught and fast leaner.
Completing my Master of Engineering in Electrical Engineering with a research topic: Development of a blockchain-based smart contract data provenance tracking application within a smart manufacturing environment.
I am an experienced full stack developer who loves crypto and DeFi. I am a crypto investor and I spend most of my spare time researching it.
While I do not yet have professional experience working with it, I am studying it intensely. In the Udacity nanodegree program I have used
the Bitcoin Core client to sign messages in my own simplified blockchain implementation and now I am using web3, Remix, Ganache, Infura and
other tools to program with Ethereum smart contracts.
I am a very fast learner and I have mastered other fields in short time frames before. For example I founded https://www.mendi.io/ which is
a company that has created a brain training headband that can boost mental wellbeing, performance and health.
I did the original research and development for the product involving software development, electrical & mechanical engineering, neurofeedback,
neuroscience and physics.
I usually get obsessed about something, and crypto + DeFi is this thing for me now. I am a very curious person and I love to learn. I will finish
the Udacity nanodegree soon and I will start the Consensys Blockchain Developer Bootcamp the 1st of September so I will have a good grasp of Ethereum.
I am currently working in one of Swedens largest Fintech companies so I know how build, operate and maintain software systems at scale.
I love finance as a field and I am very interested in learning more about it, and also to build the future financial systems is my dream.
While I do not meet all if your requirements, I believe I can be up and running in a very short time.
Looking forward to hearing from you,

I have developed arbitrage trading bots for the Defi ecosystem, lead the solidity development for a winning Chainlink hackathon NFT project, and currently work in the medical technology field as a robotics software developer.
I have experience with many of the common tools and frameworks used in the Ethereum ecosystem, namely Truffle, Ganache, Remix IDE, Infura, Geth, and web3js. I have a strong preference for the Brownie framework due to its Python integration.
My experience in the heavily regulated avionics and medical industries and their required stringent software testing standards lends itself well to blockchain development, when bugs can lead to catastrophic losses and exploit. As such, I take a test driven development approach to solidity development, writing high coverage unit tests before coding.
My dream is to build world changing applications in the DeFi space, and help bring open and free banking to all.

OpenAI, I am committed to delivering pioneering and impactful applications that improve the lives of millions worldwide.
I am very good at Rust, Typescriot, Javascript and Solifity, and well versed or I would say an expert in the blockchain technology and it's aspects. I have worked mybutts of learning and building open source products for the past 3 years and I can confidently say that I can do anything blockchain.
I am passionate about the industry and will keep working in this industry for a very very long time.
