Top SchoolDaichi Kobayashi is an IT consultant and software engineer with four years of experience building secure web and embedded systems, currently working as a PMO at North Sand while running parallel website build and large-scale migration projects for member organizations. He has hands-on experience across the stack—C, Ruby on Rails, React/Next.js, Spring—and has architected AWS infrastructure with CDK to lift municipal applications into Japan’s Government Cloud. Daichi brings a security-first mindset from developing email security systems and holds certifications including Information Technology Security Assistants, Applied Information, and AWS SAA/DVA. He combines agile product delivery with careful cross-team coordination learned on embedded-system projects that required tight module ownership and inter-team communication. An active open-source contributor, he improved Optuna’s dashboard docs and implemented an artifact download feature, reflecting his focus on usability and developer experience. Unusually for an engineer, he also studied violin seriously at a music college before his tech career, a background that informs his disciplined, detail-oriented approach.
