Victor O.
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.

Last position:
Fractional CTO at OpsWorker
OpsWorker turns Kubernetes alerts into root-cause analyses, on top of the monitoring a team already runs. I lead the technical side: the agent architecture, the AWS infrastructure it runs on (fully inside EU regions), and the engineering decisions behind it, read-only in the cluster by default, human in the loop for judgment. The stack underneath: Amazon Bedrock and Bedrock AgentCore, agents built with the Strands Agents SDK, the Claude and OpenAI APIs, and the Kubernetes API.

About the technology
Security visibility
Security information and event management, or SIEM, collects and analyzes event data from endpoints, identity systems, networks, cloud services and business applications. It turns scattered logs into searchable timelines, alerts and investigation context. Companies use it to detect suspicious behavior, support incident response and document security operations.
Core use cases
SIEM supports security teams across hybrid and cloud environments. Typical work includes:
- Centralizing logs from servers, endpoints, firewalls and SaaS tools
- Creating detection rules for account misuse, malware and data exfiltration
- Investigating incidents through correlation, search and timeline analysis
- Building dashboards, alerts and operational reports
- Supporting audit evidence and retention requirements
Tools and integrations
The ecosystem includes Splunk, Microsoft Sentinel, IBM QRadar, Elastic Security and Google Security Operations. Strong specialists work with agents, collectors, APIs, parsers, schemas and query languages such as SPL, KQL and AQL. They also connect SIEM data with EDR, SOAR, identity, ticketing and cloud security services.
When expertise matters
Companies bring in freelance SIEM expertise during a new deployment, migration, data-source expansion or major tuning effort. Specialists can reduce noisy alerts, improve log quality and establish useful investigation workflows. In Berlin, they may support local security operations on site or collaborate remotely with distributed teams.
What professionals deliver
A capable professional can design the data model, onboard sources, define retention and access controls, and create detection content for the organization’s risk profile. Deliverables may include use-case backlogs, parsing rules, alert logic, dashboards, playbooks and operating procedures. They should explain decisions clearly to both security and infrastructure stakeholders.
How to assess quality
Look for practical evidence of production SIEM work rather than familiarity with a product name alone. Ask how the specialist measures alert relevance, validates detections, handles missing telemetry and separates real incidents from false positives. Experience with cloud logging, endpoint telemetry, identity signals and incident response is valuable, as are clear communication and disciplined documentation.
Frequently asked questions
Questions about SIEM? Start with the answers below.
SIEM is used to collect, normalize and analyze security events from many systems in one place. It helps organizations detect threats, investigate incidents, monitor user activity and preserve evidence for security reviews.
SIEM provides broad event correlation across identities, networks, applications, cloud services and endpoints. EDR focuses on endpoint detection and response, while SOAR coordinates automated actions; many mature security operations use all three together.
A strong SIEM specialist often understands cloud logging, network security, identity and access management, endpoint telemetry and incident response. Query languages, scripting, API integration and familiarity with SOAR workflows also help turn collected data into useful action.
The right level of SIEM experience depends on the scope. A focused source integration or dashboard may need a different profile from a full platform rollout, detection engineering program or migration between products; the specialist should have delivered comparable work in production.
Much SIEM work can be completed remotely because configuration, queries, dashboards and documentation are handled through secure access. On-site collaboration in Berlin can still be useful for workshops, architecture decisions or incident-response exercises, subject to the organization’s access policies.
Good SIEM detection content is tied to a clear threat scenario and supported by reliable telemetry. Review how the specialist tests rules, controls false positives, documents investigation steps and updates detections as systems and attacker behavior change.
Common SIEM platforms include Splunk, Microsoft Sentinel, IBM QRadar, Elastic Security and Google Security Operations. Product choice depends on the existing cloud environment, data sources, query needs, operating model and the organization’s security objectives.
Freelancers working with SIEM often handle discovery, log onboarding, parsing, detection rules, dashboards and incident workflows. They need to work carefully with sensitive data, communicate with security and IT stakeholders, and leave behind documentation that the internal team can maintain.
