Handle failure early
Validation, retries, empty states, and recovery belong in the first design, not the final polish.
About · Belgrade, Serbia
From management to building software.
My degrees are in international management and human resources. I moved into engineering through full stack web development and computer science training at BloomTech, then worked as a frontend developer at OMP and BlueGrid before joining Zühlke in 2024.
Today I have seven years of practical development experience. My work spans React and Next.js interfaces, Node.js and C#/.NET services, Azure workflows, and Android notifications. I like following a feature through all of those layers, including how it recovers when something goes wrong.
Working principles
How I tend to work.
Write down the contract
Types, schemas, and tests make boundaries easier to change without guessing.
Keep the design small
I add infrastructure or abstractions when a current requirement needs them, not in case a future one might.

Software EngineerFeb 2024 to Present- Designed and built Azure Durable Functions batch processing with per delivery retries and a poison queue; used Cosmos DB ETags and retries to prevent concurrent updates from silently overwriting store data.
- Proposed and built Azure Web PubSub updates replacing polling every 60 seconds, so store staff see delivery changes without waiting up to a minute.
- Built core features for a Next.js store operations PWA: navigation, notes, tasks, deliveries, feature flags and offline access to previously loaded data.
- Built user feedback for an LLM assistant, saving ratings and comments with the conversation history.
- Built Kotlin Android notifications with Firebase Cloud Messaging, using managed configuration to subscribe devices to their store’s topic, and added the GitLab APK pipeline.
- Delivered regional and area loss reporting across React and C#/.NET APIs, with configurable periods, loss against budget and completion rates for recommended store actions.
- Introduced Playwright testing across two apps, including authenticated workflows. Added GitLab CI tests with a production Next.js build and seeded Cosmos DB emulator.
