I am a Senior Blockchain Engineer with over 10 years of experience specializing in decentralized protocols, real-time systems, and team leadership.

My key responsibilities include designing and maintaining Substrate pallets and integrating EVM and Solana chains.
Throughout my career, I have contributed to numerous Blockchain projects, including Acala, where I helped develop the first Parachain that joined the Polkadot ecospace.
