What I'm looking for

I am looking for a role that challenges my skills in blockchain and full-stack development while offering opportunities for mentorship and team leadership.

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

Throughout my career, I have led teams and mentored 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 built a React/Next.js frontend that enabled seamless wallet connectivity. I take pride in my ability to mitigate vulnerabilities and optimize contract performance, which has significantly enhanced user experience and application reliability.
