01. About Me

I'm a self-taught blockchain specialist passionate about decentralized technologies and building secure Web3 applications.

Currently working as a Solidity Smart Contract Developer at iEscrow.io, where I develop production-ready smart contracts for an international cryptocurrency project. I collaborate with global teams across 5+ countries using async communication.

My journey into blockchain started with a curiosity about how DeFi works. What began as learning Solidity tutorials turned into building full-stack dApps, and eventually landing my first remote blockchain role. I'm continuously learning and contributing to the Web3 ecosystem.
