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 CSV review flow that runs in the browser. Both pages link to the code and list the tests.
CSV import, validation, and review
Batch Transaction Processor
A CSV import in three steps. It validates large synthetic files, points to problems in individual rows, and keeps the review state when moving between steps.
