About Daniel

Are you looking for an experienced Solidity developer with a deep understanding of blockchain technologies and smart contract security?

As a trained IT security specialist with solid experience in blockchain and web development, I implement stable, secure, and customized smart contract solutions on Ethereum and EVM-compatible chains. My tech stack includes Solidity, JavaScript/TypeScript, Node.js, React, Next.js, as well as modern development and security tools such as Hardhat, Truffle, Foundry, OpenZeppelin, Slither, and MythX.

I not only develop new smart contracts and decentralized applications (dApps) but also optimize existing systems – always with a focus on security, gas efficiency, and a clean codebase.

Furthermore, I have experience in integrating Web3 technologies into existing systems, whether it's wallet integration, tokenomics, or interfaces to DeFi and NFT projects.

In addition to my project work, I also support beginners and students in learning Solidity, blockchain architecture, and smart contract security – practically, understandably, and aligned with current standards.

I look forward to your inquiry!
