I’m a junior front-end developer with experience in commercial projects and freelancing, participating in the development of web solutions for real business goals. I collaborate with teams to ensure product quality, and I’m constantly improving my professional level. I enjoy turning design into working interfaces with strong attention to UI/UX.

In my Freelance at UpWork (Jun 2024 — Present), I created responsive websites using HTML, CSS, and React with a focus on clean UI and smooth user experience. I translated Figma designs into pixel-perfect layouts, building reusable React components and applying modern UX/UI principles. I also ensured Bootstrap cross-browser compatibility and worked on performance optimization.

As a Front-end developer at BugBuster School (Aug 2024 — Nov 2024), I created an online school website with courses on testing, working with HTML, CSS, PHP, and a bit of JS. I updated and actualized information, handled data submission forms, connected online PHP chats, and performed SEO optimization. This role strengthened my ability to deliver complete, user-focused pages that work reliably.

At StartUp EnkoWeb (Jan 2025 — May 2025), I participated in the creation of design for a web development studio and worked with React, CSS, and PHP for form development. Later, at Alchemists Team (Oct 2025 — Mar 2026), I developed and supported high-conversion landing pages and web interfaces—from responsive projects from scratch (HTML5, CSS/SCSS, JavaScript, React, TailwindCSS) to logic and integration (custom JS scripts, validation and data submission, third-party APIs, and analytics). I also focused on optimization: speeding up page loading, maintaining cross-browser compatibility, and fixing bugs in legacy code.
