Full-time blockchain dev with over 4+ years experience

In my previous capacity as a Co-founder @ParakeetDAO, I was the lead blockchain developer writing smart contracts with security as priority. I was responsible for integrating various EVM based chains to the bridging contract which enable any ERC721 NFT to be bridged across 7 chains (Ethereum, AVAX, Optimism, Arbitrum, Polygon, BSC and Fantom). I also acted as the liaison between the external audit team and the other internal developers and UI team. I have also worked as core contributor to the Ethereum foundation primarily focussed on optimising and developing smart contracts and EIPs on top ERC20/721/1155 and other major standards. Before getting into web3 world, I was working as a senior software developer with iontrading (iongroup.com), building trading software solutions for top investment banks around the globe. From my 2-year stint at ION, I learned a lot about traditional finance.

Smart Contract Engineer

I am a smart contract expert with 16 years of self taught experience in the web development. I started my part time job in 2011. I have designed UIs, coded SEO-centered FE/BE apps and deployed more than fifteen websites, from small businesses to company websites. Before this job, I was working on the football team fans page, Vbulletin Hacks, Weblog themes and Chatbots. 2016 May I joined Ronak software Group as full time web developer and there I've been worked on some projects including Nested and River with related auxiliary apps like app store and admin panel. At 2017 I got familiar with blockchain. I built my own mining farm and managed it remotely by microcomputers and there was my first experience with blockchain APIs and services. Thanks to the scam projects which made me deep dive into the Solidity to understand projects. I believe Ethereum beside it's scaling solutions are incredible platform for building decentralized applications. In my free time, in addition to sports, cooking or playing video games, I research on security topics. Following web3 communities on twitter is also one of my favorites. I like the connections and the things help the people connect each other.

* Feedback from clients... - Takeo is an amazing developer who's extremely dedicated to his job. His robust knowledge of web3 & web2 programming, along with his passion for problem-solving was impressive, to say the least. Takeo helped in developing complex scripts to help us generate metadata & art for RatDAO. His patience and problem-solving skills also shined through in the smart contract development of our NFT mint. Takeo helped us launch a smooth, pain-free mint with zero hiccups. Aside from the smart contract development, Takeo's support along the way was great. He went above and beyond for us when we needed it. I knew I could always count on him for help when brainstorming new ideas, fixing bugs, and additional smart contract development. - Takeo was the incredibly talented dev for our 'just for fun' NFT Project, SOL Summer. Takeo is incredibly smart and on top of current happenings. Whenever we ran into a sticky moment, Takeo troubleshot the issues and came up with strong solutions. I look forward to working with Takeo again soon, and you'll be lucky if you work with him too! - Takeo was very professional and amazing to work with. He was very detailed and saw the project through to the end. Very knowledgeable w/ Rust and Candy machine! Really appreciate Philip's assistance with our project! - Takeo and I worked on an NFT project, actually a gaming & metaverse ecosystem. He is a great developer. I recommend him.
