Curious developer with a math background
I'm a curious and highly independent developer with a massive background in applied math and machine learning. I am coding for more than 8 years, starting with IOS jailbreaks and games reverse engineering. I'm developing backend for 5 years and managing software development teams for 3 years. I have successfully delivered more than 15 projects as a team lead and tonnes of projects as a backend developer. I have been developing scalable data mining tools, social networks botnets, low-latency APIs, machine learning integrations and more! My biggest project was online gaming web site (100k+ MAU) for multimillion telecom company. I was heart of both operations and backend development. I have created the roadmap and hired several teams. Since the project was urgent I've designed and implemented the whole backend and protected it from several hackers attacks My craziest project was Instagram data mining botnet based on 1k+ accounts, mining 1M+ social interactions per day. On a top of data mining tool I’ve developed behavioral research module, which was utilizing the data and optimizing mining patterns. My funniest project was Tinder style service for searching flats, with interiors style recommendation system based on sophisticated linear algebra approach (Gram Matrices + PCA) applied to VGG neural network intermediate tensors. I've combined it with Approximate Near Neighbors solution by Spotify and made Telegram bot as the interface. My most valuable experience was teaching others how to code and writing tonnes of educational and inspirational articles about IT.

Senior Smart Contract Engineer
About Me As a seasoned Solidity smart contract engineer with over 4 years of experience, I bring an in-depth understanding of DeFi, NFTs, DAOs, dApps, blockchain oracles, EVM, cross-chain bridges, layer 2 scaling solutions like optimistic and zero knowledge (ZK) rollups and the wider web3 ecosystem. With a specialty in Solidity smart contract development, I've contributed to numerous web3 and DeFi projects since 2018 and delivered hundreds of production-ready smart contracts while ensuring best practices and security. Combining my technical proficiency with a native-level English fluency, I am a skilled communicator, adept at remote collaboration, and always focused on delivering results in this rapidly evolving sector. If my expertise aligns with your needs, feel free to schedule a call with me directly through Calendly (https://calendly.com/mihailo-maksa/30min). Achievements Below are some of my key achievements and results: I built the smart contracts for the Avix Finance protocol, a permissionless tokenized volatility DeFi protocol designed to track the price of VIX on-chain. For the LongTerm Finance protocol, a tokenized index fund protocol that tracks the market capitalization of the entire altcoin market on-chain, I was responsible for developing its entire suite of smart contracts. I also developed the MAJR DAO governance smart contract system from scratch, along with a suite of supporting contracts that enable complex functionalities such as NFT minting and staking, liquidity and staking rewards, on-chain data storage, token vesting, and payment splitters. Smart contracts I've developed have undergone multiple audits by Hacken, a leading smart contract security auditor. Each audit received exceptional scores, consistently above 9 out of 10, with no critical bugs identified. See audit 1 (https://audits.hacken.io/majr/sca-majr-erc721-jul2022) and audit 2 (https://audits.hacken.io/majr/sca-majr-erc20-vesting-staking-erc721-nov2022/) for more details. During my tenure at TokenFlow, I delivered over 50 custom, production-ready smart contracts for various web3 clients. For a brief period of time, I was also working with Radiant Capital and OffBlocks. Smart contracts I developed for OffBlocks were also audited by Hacken (https://audits.hacken.io/offblocks/sca-offblocks-escrow-mar2024/). Currently, I'm leading smart contract development at the Intuition Protocol and contributing to the overall growth of the Intuition ecosystem. My work at the Intuition has been audited by Trail of Bits, with the audits publicly available (https://github.com/0xIntuition/intuition-contracts/tree/main/audits/tob). Job expectations I expect to work on exciting tech that will have a genuine impact in the web3 space, and my favorite areas of doing so are currently: omnichain interoperability, layer 2 scaling solutions (especially rollups), liquid staking derivatives (LSDs) and DeFi in general (lending protocols, AMMs, etc.). Aside from that, I expect that my job will be 100% remote, with the option to get paid in stablecoins such as USDC or USDT, and it should ideally also include the token-based compensation. Finally, I really appreciate flexible working hours and asynchronous work environment, and if there is one thing that I'd like to avoid, that's definitely the excessive number of meetings that stop everyone from getting anything actually productive done.

I'm senior Java developer and I want to get into blockchain
Hi, I'm Java developer with almost 6 years of professional experience. I live in Poland and I work remotely for 2 years. Now I work as blockchain developer in Future Processing. I started this new role on April 2022. So far I created small smart contract for storing footprint hash. It is implemented using Hardhat framework. My next task was to bring back old project (betting app for World Cup, this is completely internal application). This app is using Ethereum but is not deployed to mainnet - we have our own, private network. Technologies: React, Solidity, web3.js, Express.js, Truffle. Now I started learning Hyperledger Besu. My previous role in Future Processing was senior Java developer. I was working in small team (up to 4 developer and one PM) with our British client. I was responsible mostly for developing new features. I was very independent, almost every time I had to contact with client for more details about tasks. Before Future Processing I worked: - Objectivity (01.2020 - 08.2020) - Java, Spring 5, Spring Boot 2, Angular, Typescript, Postgres - Ultimo (01.2019 - 12.2020) - Java, Spring 5, Spring Boot 2, Angular, Typescript, MongoDB, Oracle DB - Sii Poland (05.2015 - 12.2019) - Java, Spring 2 - 5, Spring Boot 2, Web Sphere As you can see, my previous experience is mostly Java-oriented. Last year I decided to change career direction to blockchain developer so I started to learn this new technology. I started with reading "Mastering Bitcoin" and "Mastering Ethereum". I tried Corda (as Java-based blockchain technology), in Future Processing I'm learning Ethereum and related technologies. At home I learn Rust and Polkadot/Solana blockchains.

Senior Smart Contract Engineer
About Me As a seasoned Solidity smart contract engineer with over 4 years of experience, I bring an in-depth understanding of DeFi, NFTs, DAOs, dApps, blockchain oracles, EVM, cross-chain bridges, layer 2 scaling solutions like optimistic and zero knowledge (ZK) rollups and the wider web3 ecosystem. With a specialty in Solidity smart contract development, I've contributed to numerous web3 and DeFi projects since 2018 and delivered hundreds of production-ready smart contracts while ensuring best practices and security. Combining my technical proficiency with a native-level English fluency, I am a skilled communicator, adept at remote collaboration, and always focused on delivering results in this rapidly evolving sector. If my expertise aligns with your needs, feel free to schedule a call with me directly through Calendly (https://calendly.com/mihailo-maksa/30min). Achievements Below are some of my key achievements and results: I built the smart contracts for the Avix Finance protocol, a permissionless tokenized volatility DeFi protocol designed to track the price of VIX on-chain. For the LongTerm Finance protocol, a tokenized index fund protocol that tracks the market capitalization of the entire altcoin market on-chain, I was responsible for developing its entire suite of smart contracts. I also developed the MAJR DAO governance smart contract system from scratch, along with a suite of supporting contracts that enable complex functionalities such as NFT minting and staking, liquidity and staking rewards, on-chain data storage, token vesting, and payment splitters. Smart contracts I've developed have undergone multiple audits by Hacken, a leading smart contract security auditor. Each audit received exceptional scores, consistently above 9 out of 10, with no critical bugs identified. See audit 1 (https://audits.hacken.io/majr/sca-majr-erc721-jul2022) and audit 2 (https://audits.hacken.io/majr/sca-majr-erc20-vesting-staking-erc721-nov2022/) for more details. During my tenure at TokenFlow, I delivered over 50 custom, production-ready smart contracts for various web3 clients. For a brief period of time, I was also working with Radiant Capital and OffBlocks. Smart contracts I developed for OffBlocks were also audited by Hacken (https://audits.hacken.io/offblocks/sca-offblocks-escrow-mar2024/). Currently, I'm leading smart contract development at the Intuition Protocol and contributing to the overall growth of the Intuition ecosystem. My work at the Intuition has been audited by Trail of Bits, with the audits publicly available (https://github.com/0xIntuition/intuition-contracts/tree/main/audits/tob). Job expectations I expect to work on exciting tech that will have a genuine impact in the web3 space, and my favorite areas of doing so are currently: omnichain interoperability, layer 2 scaling solutions (especially rollups), liquid staking derivatives (LSDs) and DeFi in general (lending protocols, AMMs, etc.). Aside from that, I expect that my job will be 100% remote, with the option to get paid in stablecoins such as USDC or USDT, and it should ideally also include the token-based compensation. Finally, I really appreciate flexible working hours and asynchronous work environment, and if there is one thing that I'd like to avoid, that's definitely the excessive number of meetings that stop everyone from getting anything actually productive done.

I'm senior Java developer and I want to get into blockchain
Hi, I'm Java developer with almost 6 years of professional experience. I live in Poland and I work remotely for 2 years. Now I work as blockchain developer in Future Processing. I started this new role on April 2022. So far I created small smart contract for storing footprint hash. It is implemented using Hardhat framework. My next task was to bring back old project (betting app for World Cup, this is completely internal application). This app is using Ethereum but is not deployed to mainnet - we have our own, private network. Technologies: React, Solidity, web3.js, Express.js, Truffle. Now I started learning Hyperledger Besu. My previous role in Future Processing was senior Java developer. I was working in small team (up to 4 developer and one PM) with our British client. I was responsible mostly for developing new features. I was very independent, almost every time I had to contact with client for more details about tasks. Before Future Processing I worked: - Objectivity (01.2020 - 08.2020) - Java, Spring 5, Spring Boot 2, Angular, Typescript, Postgres - Ultimo (01.2019 - 12.2020) - Java, Spring 5, Spring Boot 2, Angular, Typescript, MongoDB, Oracle DB - Sii Poland (05.2015 - 12.2019) - Java, Spring 2 - 5, Spring Boot 2, Web Sphere As you can see, my previous experience is mostly Java-oriented. Last year I decided to change career direction to blockchain developer so I started to learn this new technology. I started with reading "Mastering Bitcoin" and "Mastering Ethereum". I tried Corda (as Java-based blockchain technology), in Future Processing I'm learning Ethereum and related technologies. At home I learn Rust and Polkadot/Solana blockchains.
