👋 Hey Everyone

💼 I’m open to freelance, full-time, and part-time opportunities in software development.
👥 In addition to my individual work, I lead a dedicated software development team capable of delivering medium- to large-scale projects.
📫 Feel free to reach out at my Email or Telegram to discuss potential collaborations.

Hi, I'm Anton — a senior software engineer (10+ years) specializing in AI/ML, blockchain, full-stack web development, and web performance optimization, with expertise in JavaScript/TypeScript, Solidity, Rust, Python, and C++.

  • AI / Machine Learning — Proficient in machine learning and deep learning with expertise in PyTorch, TensorFlow, transformers.js, scikit-learn, Matplotlib, NumPy, and pandas; experienced in neural networks, transformers, and LLM fine-tuning, as well as data preprocessing, model optimization, and deployment for tasks including prediction, classification, and natural language processing
  • Blockchain Development — Proficient in smart contract and dApp development across Ethereum, Bitcoin, BNB Chain, Arbitrum, Base, Polygon, Avalanche, Polkadot, and Kusama; experienced with DeFi, NFT, and DAO protocols, using frameworks like Solidity, Hardhat, Foundry, OpenZeppelin, and tools such as ethers.js, web3.js, viem, wagmi, rainbowkit, polkadot-sdk, uniswap-sdk, TheGraph, IPFS, and scaffold-eth
  • Web Full-Stack Development — Skilled in building scalable front-end and back-end applications with TypeScript/JavaScript, React.js, Next.js, Vue.js, Nuxt.js, Gatsby, Preact, Eleventy, Node.js, and FastAPI; experienced with GraphQL, PWA development, and test-driven development (TDD)
  • Web Performance & UI/UX Optimization — Specialized in web performance engineering and user experience design, leveraging tools such as Core Web Vitals, Lighthouse, WebPageTest, PageSpeedInsights, and Speed Curve, with expertise in responsive design, accessibility, and modern performance best practices

In recent years, I’ve collaborated with the Google Chrome team and the Nuxt team on AI engineering, web front-end development, performance optimization, and best practices in modern web frameworks (React.js and Vue.js), with a strong focus on AI automation and user experience improvements.

These days, I’m passionate about advancing AI technologies, with a focus on machine learning, deep learning, generative AI, and AI agentization, while also applying my expertise in blockchain through smart contract, dApp, DeFi, NFT, and DAO development.

  • 🌱 I’ve been working on web performance optimization and UI/UX improvements with modern frameworks like React.js and Vue.js.
  • 🌱 I’m currently focused on AI and blockchain technologies, exploring applications in machine learning, generative AI, and decentralized systems.
  • 🤔 I’m looking to contribute to building AI-driven products as well as dApps, DeFi, NFT, and DAO solutions.
  • 💬 Ask me anything about full-stack web development, performance optimization, UX best practices, blockchain development, or AI/ML.
