Volodymyr Markovych

I’m a frontend developer with 4+ years of experience building performance-focused Angular and React applications for client-facing, production websites. I focus on measurable results—refactoring legacy codebases and improving Lighthouse scores (60 → 90+)—while keeping UIs reliable and maintainable.

In my work, I implement Server-Side Rendering (SSR) to enhance SEO and initial load performance, and I use lazy loading and bundle optimization to reduce load time. I build reusable UI components across multiple projects, improving consistency and cutting duplicated implementation work.

I’ve integrated third-party services—AdTech (GoogleTagManager, AdSense, AdOcean), Stripe, and REST APIs—across 10+ websites to support dynamic ad banner rendering and improve estimated ad placement value by 150%+. I’m comfortable working in fast-paced, multi-project environments and collaborating with cross-functional teams to clarify requirements and deliver updates.

When issues hit production, I resolve front-end defects and maintenance problems to improve stability across client websites. I also use AI tooling to speed up development and quality—ClaudeCode, Codex, GitHub Copilot, and localLLMs—supporting AI-assisted code review and smoother iteration.
