Work History

  • Frontend 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.

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.
