Last position:
AI Training Engineer at Confidential AI Research Client
- Codebase Evaluation & Problem Design: Designed and stress-tested complex software engineering problems against large open-source Python codebases (including pandas), requiring deep context acquisition and architectural understanding to produce well-scoped, realistic problem statements aligned to strict correctness guidelines.
- Agent Failure Analysis: Assessed LLM coding agent solutions for correctness and completeness, identifying meaningful failures across edge case handling, dtype behaviour, and multi-column NaN propagation logic; documented findings with precision for downstream evaluation use.
- Programmatic Test Suite Development: Authored comprehensive pytest suites to programmatically verify agent-generated solutions against defined requirements, with deliberate coverage of boundary conditions and failure modes not caught by naive implementations.
- Containerised Environment Engineering: Built and debugged Docker environments for reproducible agent execution, including git-based repository provisioning, dependency pinning with npm ci, and multi-stage Dockerfile authoring across Linux-based containers.

About the technology
Core scope
Network infrastructure is the layer that keeps users, sites and services connected. It covers routing, switching, wireless, firewalls, VPNs and the links between offices, data centers and cloud networks. Teams also search for this work as network engineering, network operations, or Cisco networking.
What experts deliver
- LAN and WAN design for offices and branches
- VLAN, routing and subnet planning
- Wi‑Fi rollout and coverage tuning
- Firewall, VPN and access control setup
- Cloud connectivity and hybrid network links
Common tools
Strong specialists work across Cisco, Juniper, Arista and VMware NSX, plus monitoring and automation tools such as NetBox, Ansible and SNMP-based platforms. They read diagrams, review configs, and keep the network documented so changes stay safe and repeatable.
When to bring in help
Freelance expertise helps when a network needs redesign, a migration, an audit, or urgent troubleshooting. It also fits project work in Berlin offices, co-working spaces and hybrid teams that need clear handover and quick coordination with local and remote stakeholders. Many companies bring in specialists for changes that are too risky to leave to general IT support.
What strong specialists do
- Spot weak points in topology, redundancy and segmentation
- Translate business needs into clean technical designs
- Work carefully with change windows and rollback plans
- Document configs, dependencies and recovery steps
- Balance security, performance and maintainability
Signs you need one
If users see slow access, unstable Wi‑Fi, VPN failures, firewall blockers or hard-to-trace outages, the network layer needs attention. A strong Network Infrastructure specialist can isolate the fault, improve resilience, and make future changes easier to manage. This matters in environments that mix on-site systems, cloud services and multiple vendors.
Frequently asked questions
The facts hiring teams ask for most often when it comes to Network Infrastructure.
Network Infrastructure covers the systems that move traffic inside and between sites. That includes switching, routing, wireless access, firewalls, VPNs, load paths and the rules that keep them secure and stable. Companies hire specialists when they need those parts designed, fixed, documented or migrated.
A strong Network Infrastructure specialist focuses on connectivity, traffic flow and resilience, not just user devices. General IT support may handle day-to-day tickets, while cloud work may focus on hosts and services. This role sits closer to the network layer that ties everything together.
A solid Network Infrastructure professional usually knows Cisco, Juniper, Arista or similar enterprise stacks. They should also be comfortable with firewall platforms, Wi‑Fi systems, monitoring tools and documentation methods such as NetBox. In many projects, Ansible or other automation tools are also part of the stack.
Network Infrastructure work often needs security, systems thinking and clear documentation. Useful adjacent skills include firewall policy design, IP planning, cloud connectivity, troubleshooting, and coordination with service owners. In larger environments, change management and vendor communication matter as well.
The right Network Infrastructure expert depends on the task. A small Wi‑Fi fix or firewall rule review may need focused practical experience, while a campus redesign, merger, or data center change needs someone who has handled complex networks before. Ask for relevant project work, not just broad claims.
Yes, much of Network Infrastructure work can be done remotely if configs, monitoring access and documentation are in place. Some tasks still benefit from on-site presence, such as rack work, cabling checks, Wi‑Fi surveys or cutovers. In Berlin, many teams use a mix of remote planning and on-site execution.
Look for clear diagnostics, safe change planning and clean documentation in a Network Infrastructure profile. Strong specialists explain why a design choice matters, how they would test it, and how they would roll back if needed. They should also describe real outages, migrations or audits they have handled.
Network Infrastructure is the broader term, and Cisco networking or network engineering are common ways people refer to parts of it. In many companies, the work spans Cisco, Juniper, Arista, wireless and security tools rather than one vendor alone. When you brief a freelancer, describe the actual environment instead of only the label.
