SUMMARY

Senior Front-End Engineer with 9+ years of experience building web applications. Specialized in React, TypeScript, and Next.js with hands-
on expertise in state management, REST API integration, and frontend testing. Proven track record of modernizing legacy codebases,
building reusable UI components, and establishing E2E testing practices.

At Finsight, spent 4 years developing frontend features for a fintech platform — I built new tools and products within the ecosystem,
contributed to frontend architecture decisions, migrated state management from Redux to React Context API, modernized legacy
components, and built a Storybook component library. Earlier experience includes e-commerce and iGaming projects.

Seeking a Senior Frontend role where I can apply my experience, contribute to meaningful products, and grow further as an engineer.
