Junior Front-End Developer

I am a highly motivated junior developer with 1 year of experience in commercial software
development. Over the past year, I have been actively involved in the dynamic growth of a fintech
company specializing in the development of various payment system products and solutions for
both B2B and B2C businesses, as well as ERP and CRM for eCommerce.

I worked on a groundbreaking project related to Central Bank Digital Currency (CBDC), positioning
the startup as a pioneer in the financial technology market. As a junior developer, I am participating
in the development of the back office, mobile e-wallet, and other auxiliary systems. We are actively
integrating various banks into our system to enhance its capabilities. The project relies on cutting-
edge technologies, including DDD, Stellar blockchain, React, Next.js, TypeScript, ANTD, MUI,
React Query, and Jotai, among others. Its complexity lies in the integration of a multitude of
interactive elements such as forms, tables, charts, etc. Implementing non-standard UX approaches
and ensuring optimal project performance are integral parts of my responsibilities.

I'm a junior front-end developer with solid self-management skills and a constant curiosity for new
technologies. I enjoy working in a team, take deadlines seriously, and always aim to deliver my
best. I'm focused on growing both as a developer and a professional, and I’m excited to keep
learning and evolving.
