What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth opportunities.

I am a full-stack developer with over 8 years of experience in building scalable web applications, developer tools, and decentralized platforms. My journey has led me to lead full frontend and backend development at Totem Live Accounting, where I designed robust off-chain architecture and modular systems. I pride myself on being an adaptable engineer, rapidly learning new ecosystems and delivering production-ready features efficiently.

Throughout my career, I have developed a strong technical foundation, working with technologies such as Python, Golang, React, and Node.js. My notable achievements include launching a successful DApp that raised over $1 million in a Polkadot Parachain auction and implementing innovative solutions like a dual on/off-chain proof system. I am passionate about creating impactful software that enhances user experience and drives engagement.
