Senior Ethereum Solidity Developer

In the past I have been the lead architect of LTO Network where I designed and implemented the automated  creation of "Real World assets" (Ownables), including bridging them as NFTs to EVM Chains and I developed the core concept of adding the NFTs to the in-house built and Uniswap V3 based Equity Platform using Solidity, AWS, NodeJS, ReactJS/NextJS, NestJS.
I am looking for a project that needs a Full-Stack EVM Blockchain Developer with 9 yrs of Smart Contract (Solidity) programming experience, 2 years Front-end and Back-end experience and with great communication and social skills.

I am a Full-Stack EVM Blockchain Developer with 9 years of Smart Contract (Solidity) experience and 2 years of front-end/back-end expertise. Most recently, I served as the Lead Architect at LTO Network, where I designed and implemented the automated creation of Real World Assets (RWAs)—“Ownables”—and bridged them as NFTs to various EVM chains (Ethereum, Arbitrum, Base). I also integrated these NFTs into an in-house, Uniswap V3–based Equity Platform, leveraging AWS, Node.js, React.js/Next.js, Nest.js, and Gnosis Safe.

Beyond LTO Network, I have:

  • Developed a blockchain-based e-voting concept for the European Innovation Council (EIU) Accelerator.
  • Lectured at the University of Münster, teaching “Blockchain Basics” and “Blockchain in Practice” with hands-on Solidity programming.
  • Served as Smart Contract Core Developer at Florence Finance, focusing on Gnosis Safe setup, code auditing, and development (Solidity, Hardhat, OpenZeppelin) with a strong emphasis on testing and code coverage.

I’m now looking for a project that not only requires my robust technical expertise as a Full-Stack Blockchain Engineer but also values strong communication and teamwork skills.
