What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can leverage my skills in blockchain and full-stack development to drive impactful projects.

As a Senior Full Stack & Blockchain Developer with over 7 years of experience, I specialize in building scalable, secure, and high-performance applications across web, mobile, and blockchain ecosystems. My expertise includes developing smart contracts, trading engines, and DeFi protocols, with a strong emphasis on performance, usability, and code quality.

Throughout my career, I have successfully led teams and mentored junior developers, ensuring the deployment of robust applications in cloud-native environments. My recent role at smartARK DeFi involved developing and deploying Ethereum smart contracts for DeFi features, where I also led smart contract audits to mitigate vulnerabilities. I am passionate about optimizing application performance and enhancing user experience through innovative solutions.
