Anastasiia Sihetii — Product Designer · Design Engineer

A product designer working as a design engineer. I have 5+ years of experience designing product interfaces across agency, startup, and enterprise environments. At OneReach.ai, I designed two enterprise products: an AI UI builder and an agent based task platform.

On my current product, I own the whole front end: product decisions, a design system in code, and the React and Next.js that ships to production, with no handoff. My workflow is AI native with Claude Code.

Beyond the work: I’ve mentored designers and advised a product team at Yappi Global on AI integrated design workflows. I write about AI in design for DOU and High Bar Journal, and speak at meetups, most recently with IT Cluster Transcarpathia. I gave a lecture for Projector Library on how designers can work with AI, code, and product.

A website for my birthday

For my birthday, I built a website for friends with a celebration schedule and a wishlist where gifts can be reserved anonymously.

Habit Tracking Mobile App

A mobile app built around spaced repetition. Designed end-to-end in a 2-week sprint: from a chaotic set of developer wireframes to a complete, gamified learning.
