What I'm looking for

I am seeking a dynamic role where I can leverage my full-stack development skills and blockchain expertise to drive innovative projects and contribute to a forward-thinking team.

I am a Senior Full Stack Engineer with 7 years of experience in building scalable web, cloud, and blockchain platforms. My career has been marked by a proven track record of delivering innovative solutions that have tokenized over 20 assets in just one month, increased investor accessibility by 10x, and significantly reduced costs by 80% while cutting delivery disruptions by 45%.

Throughout my career, I have honed my skills in a variety of technologies, including React.js, Next.js, Node.js, and AWS. I take pride in my ability to design and launch complex systems, such as a tokenization platform that enables real estate assets to be minted and distributed as blockchain tokens. My work has not only enhanced transparency in the art world through blockchain-based solutions but has also improved supply chain efficiency through machine learning applications.
