I’m a product-driven full-stack engineer who builds fast, intuitive, and scalable digital experiences.
I'm a full-stack engineer who builds fast, scalable, and user-centered digital products. I care about performance, simplicity, and creating experiences that feel intentional.
My work blends system design, frontend engineering, and HCI principles. I enjoy crafting clean architectures, designing intuitive interfaces, and solving problems where usability and technical depth meet.
Recently, I’ve been leading development across fintech and developer-tooling projects, including a React Native investment platform, an AI-driven golf fitting app, and an open-source repository activity tracker. I handle backend architecture, cloud infrastructure, and UI design with a product-first mindset.
I've worked in research labs, start-ups, and academic teams, often driving feature delivery, mentoring teammates, and aligning technical decisions with product goals. I value clear communication and collaborative, fast-moving environments.
Outside of work, I’m usually golfing, training, experimenting with data-driven tools, or exploring new places between Japan and Canada. I’m always building something usually a side project that mixes AI, design, and real-world problems.
