Software Engineer

Hi πŸ‘‹ I'm Rossella

I’m a Software Engineer specialized in Shopify development, currently based in Tokyo and working as a Frontend Tech Lead at Flagship LLC.

I previously worked at Flagship earlier in my career before co-founding Nama Studio, a boutique Shopify agency focused on sustainable e-commerce. After several years building and leading projects there, I returned to Flagship in a technical leadership role.

With over 6 years of experience in web development, I focus on building scalable, user-friendly e-commerce experiences that translate business requirements into clean, maintainable code.

At Nama Studio, a 100% women-led agency, I worked on Shopify development, UX design, and high-performing storefronts for ethical and eco-conscious brands. Our work helped businesses grow online while staying aligned with values such as sustainability and accessibility.

Before transitioning into software engineering, I worked in marketing and customer retention. While collaborating on the redesign of Everyman Cinema’s loyalty program, I became fascinated by how business requirements translated into technical systems. That curiosity led me to start learning front-end development through communities like FreeCodeCamp, Codebar and Women Who Code.

Alongside my professional work, I’m actively involved in the tech community. I previously co-organized events with Women Who Code and now contribute to Women in Software Engineering Japan, supporting initiatives that promote technical excellence and visibility for women in technology.

Today, I continue to deepen my expertise in Shopify and modern frontend development, while expanding my skills in React and scalable frontend architecture.

Outside of development, I love writing, whether it’s technical blog post about development or travel articles about my global adventures.
