Sergii Khilchuk
FRONTEND DEVELOPER (VUE.JS)
Frontend developer with 3+ years of experience building production web
applications with Vue.js (Composition API), Nuxt, and TypeScript.
Currently working full-time at a SaaS product company serving 1,000–
2,000 daily active users, where I contribute to architecture decisions,
refactor live codebases, and ship features that reach real users. Single-
handedly built the company's Chrome extension from scratch. I enjoy
solving complex problems — they're what push a coder to grow into an
engineer. I use AI tools to improve both quality and speed without losing
my own skills in the process.
