Mikhail Kosymov

I've built and maintained microfrontend applications for Libertex, a global trading platform serving more than 12 million clients across 120+ countries. I developed SSR applications with Nuxt, GraphQL, and WebSockets to deliver real-time trading data and features.

I designed reusable UI component systems, optimized a large-scale trading terminal for responsive market-data updates, and turned CAPTCHA into a reusable module across roughly 10 user flows. My work reduced duplication, recurring bugs, and UI-related support issues while improving consistency across the platform.

At SberUslugi.ru, I led a four-engineer frontend team, planned work, reviewed code, and onboarded teammates. I also architected an SSR web platform with Vue 3 and Vite, improving initial load performance and SEO.

Earlier, I built Vue-based admin tools at author24.ru and modernized legacy applications at snetwork.ru, reducing page load time by more than 20 seconds. I enjoy working closely with product, design, and backend teams to ship reliable, user-focused products.
