Olga Dobrozhan · HR operations portfolio

Four working prototypes you can click through. Every company and person here is invented.

Portfolio · HR operations systems

Hi, I'm Olga.

I design and build HR operations systems: HRIS setup, payroll operations, HR process design, and the automation that sits on top of them. Each prototype below takes one recurring HR ops problem and shows how I'd solve it, step by step.

You'll see what ordinary code handles, where an AI model helps, and what stays with a person. Everything runs in your browser on an invented company, Sample Co. You can edit the data and watch the checks re-run.

Four prototypes

Each one opens on five tabs: an overview, the data going in, the review as it runs, the findings, and the rules and code underneath.

How I build these

Process firstThe map of who does what comes before any code. It decides where a model belongs.
Code for the rulesAnything with a right answer is a coded check. Same input, same result, every run.
AI where judgment is neededA model handles the ambiguous cases and shows its reasoning. It never commits a change.
People decideThe system prepares and flags. A named person approves, signs and sends.

The research behind the four

Before building, I read 276 open HR operations job postings (September 2026) and coded what each one asked for. These four problems came up most often.
