How I Build

AI-first, business-aware, full-cycle.

Business Context

I work backward from the business problem, so the system solves something real instead of just looking impressive.

About

A bit about me

I’m Yarema, an 18 y.o. software engineer from Lviv, Ukraine with a background in programming and economics from Ukrainian Catholic University.
My major — IT&Business Analytics — shapes how I think about product development: not just does it work? but does it create value?

For the past year, I’ve been building at AiSDR, a YC-backed startup where I’ve helped to ship market leading agentic system for Sales and GTM teams. I am the most productive in environments where speed of execution and breaking stuff is crucial part of the job.

Outside of work, I enjoy researching geopolitical systems and financial theory. I write about these things occasionally. Also i run, travel around the world and try to get into skiing.

How I Think

My Principles

Principle 01

High-leverage thinking

I look for the move that changes the trajectory, not the one that just creates motion.

Principle 02

Clear products first

I care about interfaces that make sense immediately. Polish comes after usefulness.

Principle 03

Agency first. Always

I think, question, and recommend. I do not wait to be told what to believe.
