Work Experience
WithSecure (07.2022 – Present)
Senior Software Engineer in Test – EDR/XDR/EPP Cloud Solution
AI & Agentic Automation:
- Built Claude Agents (AWS Bedrock) that autonomously update browser environments for OLS testing – eliminated manual intervention, saved ~10 engineer hours/month
- Developed Claude Skills for reusable test automation (environment setup, log parsing, regression summary) – reduced agent code duplication by 60%
- Implemented Claude Hooks for pre-processing (inject test data, enforce prompt templates) and post-processing (validate JSON outputs, cap token usage) – improved reliability and prevented runaway costs
- Designed cost-aware prompt templates – dynamically selects Claude model (Haiku for simple tasks, Sonnet for complex analysis) based on task complexity
- Created automated prompt evaluation pipeline – tracks token usage, cost per test run, and output quality
Cloud Testing & Infrastructure:
- End-to-end testing of corporate security solutions (EDR/XDR, exchange, SharePoint)
- Network modelling and anomaly detection (AI-powered)
- Test automation on AWS (EC2, S3, CloudFront, Route53, Bedrock) and Azure
- CI/CD maintenance (Jenkins) and Python test frameworks (Pytest, Selenium)
Environment: Python, Claude Agents, Claude Skills, Claude Hooks, AWS Bedrock, Docker, Pytest, Jenkins, Git
