Elizaveta Razumenko

I am a React and React Native Developer with 3+ years of commercial experience, supported by 2 years of hands-on learning and personal project development. I focus on solving complex problems and delivering reliable, production-ready user experiences.

I build across modern web and mobile stacks—JavaScript (ES6+), TypeScript, React, React Native, Next.js, and NestJS—using strong integration patterns with REST APIs, Axios, and WebSockets. I’ve shipped features such as React Navigation, DeepLinking, Push Notifications, and In-App Purchases, while keeping code maintainable and production-ready.

My approach is grounded in performance and developer productivity. I use tooling and AI to accelerate development and improve code quality, and I’ve increased development speed by ~25–35% by introducing AI tools (Cursor) and automating routine tasks. I also improved search performance by ~30–40% response time using Algolia, strengthening user experience.

I care deeply about quality and team collaboration. I work with Firebase, Amplitude, Sentry, and Algolia for analytics and monitoring, and I continuously improve development processes with Git, Docker, and CI/CD automation (including automated PR review). I enjoy requirements discussions, align solutions with product goals, and communicate technical concepts clearly.
