I am highly communicative, attentive to details and client's needs and dive into projects with real interest. I will be asking lots of questions and suggesting approaches to order to find the best solution under the given circumstances and budgets.

People come and go - docs stay. Frontend: I'll convert your graphic layout into seamlessly functioning website: valid semanticly correct html, perfect look on any device. Experienced with various css frameworks, but mostly prefer no-framework clean css (following BEM or bem-like standards). Vanilla JS or Vue/Alpine js. I'm experienced with animations using GSAP, Three.js. Having worked with websites for 10+ years in total I can help with creating mockups and research the market to find a good solution for a case.
