Hi, I’m Petar. I’m a software engineer.
I work mainly with TypeScript, React, and .NET, across browser interfaces, APIs, and background jobs. I like following a feature all the way through, including what happens when it fails.
Selected work
Relay and Batch.
Start with Relay, a small webhook delivery system, and Batch, a browser-based CSV review flow. Both case studies link to the code and explain what I tested.
CSV import, validation, and review
Batch Transaction Processor
A three-step CSV import that validates large synthetic files, shows row-level problems, and keeps review state between steps.
