Summary
👤
Senior🎓
Top SchoolDaniil Demidovich is a Frontend Engineer with 11 years of experience specializing in TypeScript, React, MobX and Next.js, focused on delivering performant, maintainable and UX-driven web applications. He has repeatedly modernized legacy stacks into high-performance systems—raising Lighthouse scores from the 30s to ~90s and achieving 5x–10x performance gains in production. Daniil drives end-to-end feature delivery and developer experience improvements, from building component libraries and rich-text editors to introducing dogfooding and optimizing team workflows. Comfortable in fully remote, distributed teams since 2018, he prefers remote roles and values lean validation, clear ownership, and pragmatic solutions (sometimes “no code” is best). An avid student of computer science classics and an open-source contributor (notably enhancing an AI-powered rich-text editor), he blends deep algorithmic curiosity with practical front-line problem solving. He avoids shady industries and seeks teams tackling meaningful problems with modern tech and a healthy work/life culture.
