Seeking a full-time, fully remote Frontend, Lead Frontend, or Fullstack role at a company with an engineering culture that values clean architecture, design systems, and AI-assisted workflows. I bring experience owning product architecture, mentoring engineers, and building high-performance web applications — and I'm looking for a team where I can do the same.

Senior Frontend Engineer (React & Angular) — scaled a 1.5M+ user platform to 95+ Lighthouse scores
UkraineWhat I'm looking for
I’m a Senior Frontend Engineer with 5+ years of experience building scalable, enterprise-grade applications across FinTech, BaaS, EduTech, SaaS and LegalTech platforms. The most recent is EssayPro, a platform serving 1.5M+ users where I maintained high-traffic CRM systems and cabinets for more than 20 user roles and implemented analytics and experimentation using GTM, Mixpanel and GrowthBook.
Deep expertise in React, Next.js (SSR/SSG) and TypeScript, with hands-on experience in Angular and RxJS providing strong cross-framework adaptability. Comfortable owning frontend architecture independently and collaborating closely with cross-functional product teams in Agile (Scrum/Kanban) environments. Fluent in AI-assisted development workflows (Cursor, Claude Code, Copilot).
I focus on scalable state management, accessibility, secured authentication flows (JWT, SSO, and token refresh), and performance-focused rendering strategies like lazy loading and OnPush. I also mentor engineers through code reviews and architecture guidance, helping teams deliver reliable releases and continuous improvements.
