About

I’m Atsuhiro Endo, a senior software engineer based in Berlin with a passion for Web3 and building scalable web applications. I have extensive experience in full-stack development, backend (Golang, Node.js), frontend (React, Vue), and mobile (React Native), with a strong emphasis on test-driven development and modular architectures. I enjoy mentoring peers and sharing knowledge to deliver robust, maintainable software.

I’ve worked across fintech, insurtech, digital identity, and travel sectors, including co-founding a crowdfunding platform focused on French SME bonds. I am excited about leveraging Web3 technologies to empower Web2 businesses to transition into decentralized solutions, particularly through blockchain, smart contracts, and scalable cloud-native architectures.
