Work History

  • Web Developer | WCAG, ARIA

    Self-employed,

    I build fast, accessible websites that consistently pass Lighthouse audits (95+) and comply with WCAG 2.2. This helps clients get more organic traffic and reduce bounce rates for users with visual impairments. I also set up backends and APIs with Node.js, enabling faster MVP launches without needing a separate backend team.

  • Software Engineer

    VIST-m,

    Initiated the redesign and migration of an e-commerce site from Vue to Next.js, cutting load times by 60% and reducing support requests. Led the dev team using Jira and GitLab CI/CD workflows. Built an Ant Design-based admin panel, empowering non-technical managers to handle content updates independently, reducing dev load and speeding up site maintenance. Also developed the Drewnochron platform with a strong focus on clean, user-friendly UI using Ant Design.

  • Frontend Developer

    Designed and implemented responsive, inclusive UIs that improved user engagement and reduced missed goals in the app. Used React, TypeScript, and Material-UI for core features. Developed an animated, mobile-first promo site using Vue, Nuxt, and GSAP for a major marketing campaign. Additionally created responsive, cross-browser HTML email templates to support the marketing team’s outreach.
