What I'm looking for

I'm looking for a role that fosters innovation and collaboration, ideally in a company that values technology-driven solutions and offers opportunities for professional growth.

I'm a Full Stack Developer with over a decade of experience in crafting scalable web applications and decentralized blockchain solutions. My proficiency spans both frontend and backend technologies, including JavaScript, Node.js, React, Solidity, and Web3. I have a demonstrated ability to align technology solutions with business objectives in dynamic startup and enterprise settings.

In my recent role as a Senior Full Stack & Blockchain Developer at QIT Software, I developed and maintained full-stack web applications, implemented RESTful APIs, and created smart contracts for DeFi and NFT applications. My previous experiences include building scalable MERN stack applications at Webbuggs and writing Ethereum smart contracts at QuickNode. I thrive in collaborative environments and am passionate about leveraging technology to drive innovation.
