I’m a frontend / full stack software engineer with a focus on ReactJS and Next.js, GraphQL, Node.js, Python, and PostgreSQL. I enjoy building robust, scalable web applications and collaborating with international teams to deliver high-quality features. I’ve implemented features and refactored legacy functionality for US-based medical platforms as part of an international team. I’ve created backend APIs with Django + Graphene (MySQL) and integrated them with a React frontend powered by Apollo Client, including auto-generated GraphQL types. I’ve built forms with React Hook Form (validated with Zod), frontend types via GraphQL Code Generator, and wrote tests (React Testing Library) plus backend tests. I’ve leveraged Django DB optimization techniques, conducted code reviews, and worked with Storybook and Docker in a remote setup.
