Malmo, Skåne County, Sweden
I am an IT/OT Infrastructure Engineer working at the intersection of industrial systems, secure networks, and data-intensive environments, with a growing focus on large-scale research infrastructures (Big Science). My background includes network architecture, OT/ICS environments, and data center systems, supporting high-availability and mission-critical operations. I have hands-on experience designing, troubleshooting, and improving secure and resilient infrastructure in complex technical environments. I work with technologies such as Cisco, Fortinet, industrial Ethernet, and SCADA/ICS systems, combined with experience in monitoring, virtualization, and infrastructure security for critical operations. Big Science & Research Infrastructure Focus Through engagement with the Swedish Big Science ecosystem (ESS, MAX IV) and the broader European landscape including CERN, European XFEL, GSI/FAIR, and ESO I am particularly interested in how digital infrastructure supports large-scale, data-intensive scientific environments. My focus includes: Data-intensive systems and scientific computing Integration of IT and control systems (IT/OT, SCADA/ICS) High-performance and high-availability network environments Secure, scalable, and resilient infrastructure for complex instrumentation Current Direction I am open to opportunities and collaborations within: Research infrastructures (ESS, MAX IV, CERN, XFEL, ESO ecosystem) Advanced laboratories and data-driven environments IT/OT integration and infrastructure architecture I am particularly interested in projects where physical systems, data, and digital infrastructure converge.

Worked across industrial projects (EPCC) providing network infrastructure solutions, digital workflow optimization, documentation, and multidisciplinary coordination. Key responsibilities: • Designed and implemented network extensions (passive & active infrastructure). • Built lab environments (virtual + physical) for testing patches, configurations, firmware, and traffic flows. • Strengthened and modernized legacy networks; performed troubleshooting, monitoring, and security improvements. • Created data center frameworks (passive, active, operational). • Supported project management and EPCC processes (engineering, procurement, commissioning). • Coordinated with disciplines: civil, piping, instrument, electrical, HVAC, HSE, procurement, HR, and security. • Documented security framework, operational procedures, and digital workflows. • Conducted penetration testing and vulnerability review. Technologies & tools: Cisco, industrial Ethernet, virtualization (VMware), monitoring tools, firewalls/NGFW, lab environments, SCADA/automation interfaces, EPCC standards (Opercom), digital twin/engineering tools (Autodesk, Hexagon).
art of Banedanmark’s laboratory team designing and testing network solutions for the national ERTMS train control modernization project. Key responsibilities: • Built and tested production-scale lab network for ERTMS validation. • Ensured end-to-end routing and policies for overlay/underlay traffic. • Supported GSM-R and satellite-related integrations. • Verified application interoperability between sensors, controllers, and railway systems. • Coordinated with engineering teams on network architecture and testing requirements. Technologies & tools: Cisco routing/switching, industrial IP networks, ERTMS, GSM-R, lab environments, WAN/LAN/DC integration.
Operated and maintained the national backbone delivering Internet and MPLS services to private ISPs. Key responsibilities: • Monitored and troubleshot backbone WAN infrastructure. • Supported MPLS services and large-scale routing domains. • Ensured service continuity, capacity, and availability for regional ISPs. • Coordinated with NOCs and field teams for escalations and maintenance. Technologies & tools: Cisco, MPLS, backbone routing, monitoring systems, optical/transport segments.
