Ilya Rogachev — Frontend Engineer

I am a Frontend developer with 6+ years of experience building high-performance, data-intensive web applications for FinTech, energy and enterprise clients. I specialize in React and TypeScript, design scalable component architecture, and ship production features that move metrics, not just pixels. I solve hard frontend problems: • turning complex dashboards and heavy data flows into predictable, fast, and maintainable user experiences. I led the development a Micro-Frontend used by 100K+ bank customers with zero downtime and cut a critical release cycle from two months to two weeks by introducing Module Federation and coordinating cross-team integration, saving approximately $41k in delivery costs. • I designed testing and CI/CD pipelines that automated QA and covered 96% of key user scenarios, removing 40+ hours of manual QA per month. • I improved perceived performance drastically. LCP dropped 35.1% (3.7s → 2.4s) by optimizing API usage and applying targeted caching via Redux Toolkit / RTK Query. • I’ve built design systems and UI kits (40+ shared components), integrated Storybook into reviews to speed up design feedback, and delivered analytics UIs with complex tables, filtering, presets and interactive charts. Why I do it: I want product teams to trust frontend as a predictable delivery engine. Clean architecture, automated pipelines and reusable UI primitives let teams iterate faster while keeping performance, accessibility and developer experience high. I enjoy mentoring. I promoted multiple juniors to middle levels through pairing, code reviews, and DDD guidance, because growing engineers multiplies impact. Skills and core competencies • Languages & frameworks: JavaScript (ES6+), TypeScript, React (hooks), Next.js • State & data: Redux, Redux Toolkit, RTK Query, React Query, WebSocket patterns • Testing & quality: Jest, React Testing Library, Playwright, Storybook, MSW • Performance & monitoring: LCP, CLS tuning, API call optimization, caching strategies • Architecture & tooling: Micro-frontends, Module Federation, Feature-Sliced, DDD, Webpack, Vite, Turborepo • UI & accessibility: HTML5, CSS3, SCSS, Tailwind, WCAG 2.1 AA, axe-core checks • Processes: CI/CD, Git workflows, Agile, Scrum, component-driven development • Other: mentoring and tech leadership If you’re hiring for a Frontend, React engineer to drive component quality, and improve delivery velocity, feel free to reach out by email. ilya.rogachev.job@gmail.com
