Lazar Vukosavljevic

Led production-grade UniswapV2-style DEX on BNB Smart Chain, extended AMM logic, router/swapping mechanics, LP fee handling, and multi-token liquidity models. Designed and deployed Solidity smart contracts for Yield Farming, Staking, Token Launchpad, Tokenomics, Vesting, and Governance. Implemented Subgraph indexing and analytics for real-time swap/TVL/LP metrics. Architected a governance token migration system with timelocks, DAO permissions, vesting, and upgradeable contract architecture. Built secure DApp frontends with React/Next.js/TypeScript/Tailwind, including wallet onboarding, staking dashboards, lock/claim flows, and analytics charts. Implemented security best practices and audits to mitigate reentrancy, MEV, overflow, XSS, CSRF, and business-logic attacks. Managed backend microservices for indexers, notifications, RPC caching, queues, and analytics.

Built a Shimmer EVM UniswapV2 fork with extended modules for Yield Farming, Token Launchpad, LP Lockers, vesting, presale, and DEX analytics. Developed cross-chain bridging logic using LayerZero, enabling secure token/message transport across BSC, Shimmer, and EVM networks. Designed and audited smart contracts for Governance Token Presale, vesting, token distribution, whitelisting, and early investor mechanics. Delivered full-stack DApp UI using Next.js, TypeScript, Tailwind, Wagmi, and Web3Modal—featuring presale dashboards, claim portals, LP management, and NFT reward systems. Integrated enterprise-inspired identity, traceability, and permission control into DeFi components for compliance use cases. Built backend services for chain monitoring, token analytics, and price generation. Implemented secure deployment pipelines and automated testing with Jest, Mocha, Cypress. Optimized smart contract gas usage and executed audits (slither, MythX, hardhat-security).

Led development of Qbit Network, a Layer-1 EVM-compatible chain, including RPC infrastructure, node orchestration, consensus components, Wasm modules, and chain-level security protocols. Built ecosystem products: Multichain UniswapV2 DEX (Qbit ↔ BSC), Token Launchpad, Explorer, Testnet Faucet, Vault System + Leverage Trading Engine. Developed high-performance smart contracts for Vaults, Leverage Trading, Risk Engines, Funding Rates, Chainlink Oracle integration, and cross-chain asset management. Architected bridging + rollup-style features, message relayers, and state-sync modules between chains. Designed full-stack DApps using React, Vue, Next.js, TypeScript, integrated directly with custom RPC endpoints. Implemented extensive backend systems: block indexers, real-time metrics pipelines, RPC load balancers, PostgreSQL/MongoDB data storage, and admin APIs. Managed DevOps with Docker, Kubernetes, Nginx, Ubuntu, multi-node network deployment, CI/CD, node monitoring, and automated backu
