April 2026 – Present
Software Engineer I — GDi Solutions
- Helped migrate the platform's backend from Java to Node.js alongside a frontend redesign, while maintaining the Java/Vuetify version and building custom components for customers still on it.
- Designed and implemented the platform's authentication and authorization: JWT-based auth with role- and privilege-based access control, plus REST endpoints and business logic used across the platform.
- Laid much of the groundwork, together with the team, for the new platform's configuration module and sewerage network module: code structure, configuration moved into JSON, and global error handling with errors shown directly in the configuration module.
- Built many of the new platform's tools, helping move most configuration out of files and into the UI.
- Contributed components to the platform's two in-house libraries: a UI library replacing Vuetify and a shared widget library used by both the map application and the sewerage module.
- Containerized platform services with Docker, making deployments consistent and repeatable across environments.
- Built an AI-assisted configuration generator in the configuration module on a self-hosted Llama model: it turns the user's request and a description of a valid configuration into a prompt, then automatically checks the result and fixes most errors and unfinished sections that could break the application. A configuration that took about an hour by hand now takes a few minutes, depending on the hardware hosting the model.
- Wrote a Python geoprocessing tool for server-side data export for a telecommunications client, and am now turning it into a universal, ArcPy-only export tool.
April 2024 – April 2026
Junior Software Engineer — GDi Solutions
- Delivered platform features and custom work for enterprise clients across many industries, including electricity distribution, sewerage networks, telecommunications and the oil industry, from larger platform rollouts to smaller custom tools.
- Worked closely with GIS specialists, both in-house and in other offices across the GDi group in different countries.
- Built many map widgets and tools in Vue 2.7 and Vuetify, including import, export, attribute tables, drive-time analysis and custom tools for police and traffic accident data.
- Worked on the sewerage network module: feature identification, table of contents, Java backend logic and a fix for map loading.
- Built custom widgets, backend logic and tools for an electricity distribution company.
- Extended the Java backend with REST endpoints, database access and proxy logic, added backend support for tool usage logs with a frontend view to browse them, and migrated databases from MySQL to PostgreSQL and Oracle.
- Owned deployments on client Windows servers for more than 10 clients: configured Apache, set up IIS as a reverse proxy, migrated customer databases between environments, and handled production debugging and support.
- Worked with Vuex and Pinia for state management and helped define the architecture of new modules with the team.
October 2023 – February 2024
Undergraduate Teaching Assistant — School of Electrical Engineering, University of Belgrade
- Assisted in machine learning labs, helping students with practical assignments and grading submissions, with a focus on applied ML concepts and implementations.
March 2022 – May 2022
Software Engineer Intern — Microsoft Development Center Serbia
- Part of the Maps team, working on an existing web application for viewing and editing map data, with a C# backend.
- Built a proof of concept for bringing external point-of-interest data into the application: researched where the data could come from and who to ask for it, how it was structured, and how the existing system and codebase worked.
- Integrated the data into the frontend with React.js and D3.js.
