Software Engineer

With 2 years of experience at a blockchain startup, I have contributed to various Web3 projects including blockchain platforms, wallet apps, NFT marketplaces, cross-chain bridges, and DEXs. Proficient in full-stack development using Go, React, Nest.js, and Solidity, I place strong emphasis on clean code, testing, and documentation. Notably, I helped improve blockchain throughput by 66% through protocol optimization and contributed to a mobile wallet app that reached over 1M+ downloads. I aspire to become a developer who connects the philosophy of 'code-based trust' in Web3 to real user experiences.

Following my two-year mandatory military service, I’ve continued building on this foundation by actively enhancing my skills—attending Web3 meetups, engaging with the developer community, and building across diverse platforms and technologies. I’m currently seeking remote opportunities where I can contribute meaningfully to Web3 projects, and I bring with me a strong adaptability to new environments, a fast learning curve, and an open mindset toward different stacks and languages.
