About

Web developer building responsive, multilingual websites and lightweight full-stack web applications for small businesses and independent projects. Comfortable working across front-end, back-end, databases, deployment and basic SEO, with a focus on clear communication and practical solutions.

I help with business sites and landing pages from concept to deployment, responsive redesigns and mobile usability fixes, and small database-backed features (forms, dashboards, authentication flows). Also experienced with localization, deployment setup (DNS/Cloudflare) and improving website structure for SEO.
