About
Software Engineer with over 10 years of experience delivering scalable web and backend solutions across fintech, healthcare, and blockchain industries. My core expertise lies in TypeScript, Go, Node.js, NestJS, and React, with hands-on experience in building cloud-native applications on AWS and Azure, as well as developing blockchain-integrated systems using Ethers.js, Web3, and TheGraph. I'm deeply interested in working on innovative, high-impact projects—particularly in the crypto/Web3 space, decentralized infrastructure, and real-time financial systems. I enjoy tackling complex architectural challenges, improving developer experience, and building secure, maintainable systems from the ground up. My strengths include a strong problem-solving mindset, clean code practices, performance optimization, and a collaborative approach to team development. I’m also experienced in leading teams, mentoring junior engineers, and driving feature delivery in fully remote, agile environments.
