Sona Hakobyan
@sonahakobyan
Frontend Engineer specializing in React and TypeScript, building scalable, pixel-perfect UI systems for real-world products.
What I'm looking for
I’m a Frontend Engineer with 4+ years of experience building React and TypeScript applications, currently delivering solutions for international clients through Toptal’s vetted talent network.
I focus on reusable UI systems and maintainable architecture—building with React, Redux, Zustand, Tailwind CSS, and Ant Design to translate business requirements into production-ready features.
Across teams, I collaborate on scoping and priorities, run client-facing technical discussions, integrate REST APIs, and debug cross-browser and cross-device UI issues to improve stability and user experience.
Before specializing in frontend, I worked on full-stack responsibilities (authentication and customer-facing UI) and also developed geospatial algorithms using Google Earth Engine and JavaScript for satellite-based environmental monitoring, including NDVI analysis and blue-green algae estimation.
