About · Tel Aviv

Hi, I’m Andrei.

Based in Tel Aviv, I design and build practical digital products — from workplace scheduling software to a mobile relocation prototype.

I use Codex and Claude as implementation tools. I define the product behavior and interface, review what they produce, test the complete flow and make the final decisions.

I study Digital Marketing at Ariel University (2024–2027), which keeps audience and business goals close to the product work.

Background

QA taught me to look for what breaks.

I spent two years working in QA automation in Russia with Playwright and TypeScript. That experience shaped how I look at interfaces: every action has a state, and small gaps can decide whether someone trusts the result.

I now work from the user’s task outward — defining what the product needs to do, shaping the interface, checking edge cases and carrying the decisions through delivery.

Selected work

Products shaped around everyday tasks.

Mobile UX prototype

OlehAI

A mobile concept for navigating life in Israel. The prototype follows one student’s priorities, bank comparison and visit preparation; I shaped the product model, UX/UI and testing.
