I'm a Diplom-Ingenieur (MSc) in Electrical Engineering with a focus on Computer Science, and a seasoned software engineer with over two decades of experience in designing, developing, and maintaining robust backend and frontend systems. I've participated in and led the development of a wide range of software systems-spanning from scientific and geospatial applications to complex web and mobile platforms.

Throughout my career, I've contributed to more than 30 projects, including complex EU-funded research initiatives and commercial software solutions. My work has supported interdisciplinary research in environmental modeling, urban planning, medical logistics as well as parcel shipping logistics. I bring deep technical expertise in Java, Spring Boot, PostgreSQL/PostGIS, and geospatial standards (OGC/GML, metadata, routing), combined with a strong foundation in frontend technologies and mobile app development. In addition to software development, I have a solid background in Linux systems administration, networking, and DevOps practices.

I have worked both as an independent consultant and within academic institutions, primarily serving clients and collaborators across the DACH region and wider Europe.

Network and systems administration, including the configuration, maintenance, and monitoring of LAN infrastructure and Windows 2000 Active Directory services. Responsible for ensuring network reliability, user access control, and overall system stability.

IT Support Technician

microNet, Belgrade, Serbia
1999-2002

Customer support and deployment of enterprise network services and hardware, including installation and configuration tasks.

Projects

I have participated in over 30 software development projects across various domains, but only a selection of representative projects is listed here. These examples highlight the range and depth of my experience.

Expedit

Freelance | AntSoft

Expedit is a logistics software suite designed to streamline shipment handling for courier partners. The core component, Expedit Client, provides users with a user-friendly interface to create, edit, and track shipments and addresses. It automatically communicates with a central server to sync data, eliminating manual transfers.

Key functionalities include:

  • Automated data import and validation (e.g., city name autofix, batch data correction)
  • End-of-Business-Day processing with automated label printing and report generation—even offline
  • Customizable printing workflows, including barcode labels and internal reports
  • Comprehensive shipment and address history, with powerful filtering, sorting, and duplication tools
  • Routing module that calculates optimal delivery routes based on destination addresses.

I was solely responsible for the design, development, and ongoing maintenance of the entire software system.

AiRMOUR - Opening up the skies for medical emergency drones

Robots Expert Oy

AiRMOUR is an innovative project focused on designing and implementing a GIS-supported platform for medical drone operation. The system integrates spatial data from various sources—such as road networks, health facility locations, and environmental constraints—to enable the planning and definition of optimal air routes for drones delivering medical supplies. By combining real-time geographic insights and advanced algorithms, AirMour aims to enhance the efficiency and reliability of drone-based healthcare logistics.

In my role, I took responsibility for the full-stack implementation of the GIS platform. On the backend, I developed RESTful services using Java and Spring Boot to process and integrate spatial datasets. On the frontend, I built an interactive mapping interface with Leaflet, JavaScript, and HTML that allows users to visualize routes, explore map layers, and design drone paths.

UrbMod - multi-sector urban development impact model

TUHH

Interdisciplinary research initiative aimed at identifying optimal strategies for promoting urban health. Funded by the State of Hamburg, the project brings together experts from diverse fields—including meteorology, geography, urban planning, medicine, engineering, and mathematics—to collaboratively address the complex challenges of sustainable urban development.

Within this project I was responsible for metadata integration. My role involved harmonizing and structuring geospatial and environmental metadata from various sources to enable efficient data discovery and interoperability across research platforms. This work supported collaborative modeling and analysis in the context of urban climate and sustainability.
