What I'm looking for

I want to build high-performance, accessible frontend products with Vue/React, strong testing (Vitest/Jest + Playwright/Cypress), and modern build tooling. I’m excited about microfrontends/SSR and CI/CD-driven teams that value UX quality.

I’m a Frontend-focused engineer with 5+ years building frontend applications using HTML, CSS, JavaScript, VueJS, and React. I’m known for initiating and modernizing applications with strong attention to performance, maintainability, and user experience.

In recent roles, I migrated microfrontend and large frontend apps to Vue 3 (including SSR support) and automated internationalization for Vue apps. I also improved observability by making log/monitoring with datadog, and I speed up applications by decreasing bundle size and page load time.

I build reliability into delivery through unit and E2E testing using Jest, Vitest, Playwright, and Cypress, and I’ve increased test coverage by writing unit tests and end-to-end tests. I also enhance accessibility measured by Axe and Lighthouse, improving UX accessibility-wise using VoiceOver and NVDA.

Previously, I worked as a Fullstack Software Engineer, contributing to frontend and backend development with PHP and NodeJS. I enjoy taking complex systems and splitting them into maintainable parts (often SPA/microfrontend-style), while applying CI/CD pipelines with GitHub Actions and GitLab CI in Scrum/Kanban teams.
