What I'm looking for

I seek frontend roles building performant, scalable web and mobile apps where I can lead architecture, collaborate cross-functionally, mentor developers, and work in a remote-friendly, product-focused environment.

I am a Frontend Developer with four years of remote experience building and scaling complex web and mobile applications; I was promoted from intern to developer after two months through hands-on work with React, Next.js and React Native.

I have delivered and maintained multiple products (PetsCity, Basco2, Poolsea, Soul, BeAgro) and focused on UI architecture, component design, performance optimization (code splitting, lazy loading), REST API integration and spatial data rendering using Leaflet. I document and test UIs with Storybook and use testing tools such as Jest, React Testing Library, Vitest and Cypress.

I mentor and onboard junior developers (guided seven), temporarily led the frontend team handling backlog, sprint planning and Jira oversight, and continually collaborate with backend developers, UX/UI designers and stakeholders. I hold a Master's in Computer Science (Data Analysis & AI) and an Engineer's degree (Web Development).
