Богдан Колесніков

Frontend Developer with 4+ years of experience building networking and infrastructure web products, from public-facing corporate sites to router management UIs and multi-router controllers. I've worked on the cloud service dashboards, taking features from idea and design to production: SEO-optimized marketing pages, admin panels, and tools that let engineers control networks instead of fighting the UI. I'm comfortable working across the stack with React, Next.js, TypeScript, REST API and GraphQL, focusing on reusable components, clean APIs and performance.

In projects I've reduced unnecessary traffic by orders of magnitude, pushed Lighthouse scores into the green, auto-generated types based on GraphQL schema from the server, optimized requests, and set up analytics, CMS and payment/CRM integrations, so both marketing and engineering teams can ship faster on top of a predictable, maintainable codebase.
