Junior Full Stack Js & Web3 Developer

Full Stack Developer | Web3 Enthusiast | Next.js & Solidity

Hi! I am a Full Stack Developer with a specialized focus on bridging Web2 stability with Web3 innovation.

Currently completing my degree in Informatics, I have practical experience building enterprise-grade applications, including Supply Chain Management (SCM) systems and B2B Marketplaces handling real-time transactions. My core stack includes Next.js, TypeScript, Node.js, and PostgreSQL.

Why Web3?
Beyond standard web development, I have spent 4 years researching the blockchain ecosystem. I recently engineered a Decentralized Data Security System using Ethereum Smart Contracts (Solidity) and IPFS for my final thesis, focusing on AES-256 encryption and on-chain data integrity.

What I offer:

  • Frontend Mastery: Pixel-perfect slicing (Figma to Tailwind) and type-safe logic (TypeScript).
  • Backend Logic: API development (Express/Prisma) and Database optimization.
  • Blockchain Context: Understanding of Wallets, Gas, RPCs, and Smart Contract integration.

I am looking for Junior Developer or Developer Relations roles where I can contribute to building the decentralized future.

Let's build! 🚀
