Looking for a seasoned Blockchain & MEV trading bot developer to turn your smart contract and decentralized application (dApp) ideas into reality? In need of a developer proficient in Solidity or Rust to craft 'Gas-Optimized' smart contracts? Whether you aim to create ERC20 or SPL tokens, ERC721, ERC1155, or ERC404 NFTs with unique functionalities, or are wary of vulnerabilities in high-value contracts and need testing or scripts to interact with top DEX protocols—I'm here to help. With a strong expertise in EVM-compatible chains like Ethereum and Binance Smart Chain as well as Solana, I focus on delivering efficient, gas-optimized smart contracts and tailor-made dApps. My goal is to assist clients in building secure, robust smart contracts that minimize risks and prevent exploits.

I'm a Full Stack Developer with years of experience building high-performance crypto dApp, eCommerce stores, admin panels and custom business tools. Especially, I moved to Web3 industry and built a few big brand dapps. which gained 10K+ users. - Stacks Frontend : Web3 JS, React, Next.js, Vue.js, Angular, Vite, Django, Larravel, Tailwind CSS Backend: Node.js, Django, Express.js, Python Django, GoLang Database: PostgreSQL, MySQL, MongoDB DevOps and Deployment: Docker, CI/CD, Vercel, Render, Firebase Hosting, Nginx

I build Web3 products end-to-end from Solidity smart contracts and on-chain data pipelines to the Next.js dashboards your users actually interact with. I've shipped production DeFi applications, not just toy demos, and I'm comfortable owning the full stack: protocol layer, backend APIs, and frontend UI. My Web3 toolkit includes Solidity 0.8, Hardhat, Chainlink CRE, EVM tooling, and multi-chain data APIs (Mobula, Moralis, Helius, Goplus). On the frontend I work in Next.js 15, TypeScript, and React and I know how to surface complex on-chain data in ways that are actually readable to users. Recent work: I architected TokenomicsLab, a production DeFi analytics platform with a proprietary scam-detection scoring algorithm that correlates liquidity locks, holder distribution, mint/burn events, and deployer behaviour across multiple chains. I also built SentinelBridge, an AI-powered cross-chain bridge security tool submitted to the Chainlink Convergence Hackathon 2026 it uses Groq LLaMA-3.1 for real-time threat classification and Solidity circuit-breaker contracts that auto-pause bridges when risk thresholds are breached. I come from a cybersecurity background (BSc from Vilnius University, Google + Cisco certified) which means I think about smart contract attack surfaces flash-loan exploits, oracle manipulation, governance hijacks not just feature delivery. Security isn't an afterthought for me; it's how I build. I work autonomously, move fast, and use AI tooling (Claude Code, Cursor) as a force multiplier. If you're building something in DeFi, on-chain analytics, cross-chain infrastructure, or Web3 tooling I can take it from idea to production.
