Frontend розробник

from 04.2024 to now (2 years 4 months)
InsulaLabs, Дистанційно (IT)

Project #2: Pistolo.com
Implemented a complex CSS-only CTA animation for the main hero banner, perfectly synchronized with
background video, increasing primary CTA click-through rate by 15.6% compared to the previous static version.
Replaced JS-heavy animation implementations with optimized CSS keyframes and transitions, improving
animation smoothness (FPS) by 29.3% and reducing animation-related main-thread blocking time by 24.1% on
mid-range devices.
Tuned layout and visual timing to preserve a strong “wow-effect” while maintaining fast load, keeping LCP on the
homepage under 2.2s and improving mobile performance scores in Lighthouse to 90+.
Worked closely with design and product teams to iterate on micro-interactions around the hero section, increasing
average time-on-hero and scroll-through to the next section by 17.4%.
Technologies: JavaScript, HTML5, CSS3/SCSS (Advanced Animations, Keyframes
Project #1: BigClash.com
Designed a clip-path + calc()-based technique for complex shield- and drop-shaped UI components, replacing
heavy SVG/PNG masks and reducing render time on element-dense screens by 25.2%.
Standardized this approach across the project and other internal products, cutting implementation time for new
“non-rectangular” card designs by 35.9% and reducing related asset payload by 28.7%.
Coordinated work between Dev, Design, BA and PM under tight deadlines, simplifying non-critical visual details
where possible and reducing sprint spillover by 21.6%, while avoiding overtime for the team.
Led a small frontend team (task planning, reviews, communication with product owners), improving sprint
throughput by 18.8% and ensuring on-time release of the gaming platform with noticeably better UX on low-end
devices.
Technologies: HTML5, CSS3 (Advanced Layouts, clip-path, calc), JavaScript, Jira, Confluence, Agile/Scrum
