Cezary Powala

Developed and integrated advanced DeFi frontends for staking, liquidity, and token swap modules using React and Next.js. Connected complex smart contract systems to UI via Wagmi, Viem, and Ethers.js with dynamic state handling. Implemented real-time trading interfaces and liquidity views using The Graph and WebSocket event subscriptions. Built NFT marketplace dashboards with metadata, IPFS storage, and minting logic via Moralis APIs and GraphQL. Created reusable transaction hooks and smart contract utilities enabling modular UI integrations across multiple dApps. Architected wallet connection pipelines supporting cross-chain usage (MetaMask, WalletConnect, Safe Apps SDK). Integrated DeFi analytics panels powered by on-chain data aggregation through The Graph. Refactored legacy blockchain calls into unified API layers ensuring consistent data between backend and smart contract interfaces. Developed secure front-end modules for staking, liquidity management, and NFT transfers with gas-op

Developed blockchain-integrated dashboards and enterprise-grade dApp interfaces using React and Redux. Created reusable UI components aligned with Atomic Design and WCAG accessibility standards. Implemented CI/CD pipelines with Docker and GitHub Actions for production deployments. Built GraphQL-driven data visualizations and query optimization strategies. Reduced load times by 25% through dynamic imports and static asset compression. Migrated legacy architecture to TypeScript and Next.js, increasing maintainability and reducing runtime errors. Deployed component-driven testing using Storybook and React Testing Library. Integrated internal blockchain simulators to test dApp flows before mainnet deployment. Established end-to-end type safety between smart contracts and UI via TypeChain and Ethers.js. Automated front-end build validation with linting, static checks, and CI hooks.

Supported development of React-based dashboards for internal tools and Web3 visualizations. Assisted in integration of wallet authentication modules for testnet smart contracts. Built modular UI layouts using Flexbox and TailwindCSS for rapid prototyping. Participated in code reviews and front-end testing pipelines. Collaborated with UX designers to implement pixel-perfect responsive UIs. Learned practical blockchain development using Solidity and Remix environments. Implemented small-scale ethers.js functions for reading on-chain contract states. Explored React Suspense and lazy loading strategies for smoother initial rendering. Configured unit testing with Jest and component isolation for visual debugging. Contributed to frontend performance optimization experiments under senior mentorship.
