Top SchoolOctavian Ionescu is a London-based software engineer with 11 years' experience specializing in QA, test automation, and backend development. He holds a BSc in Computer Science and Information Security from Royal Holloway and has applied that security focus to hardening open-source projects such as MQTT.js, adding certificate/key handling and extensive protocol unit tests. At LSEG he designs and executes automated test suites, reviews technical designs, and tracks QA metrics to ensure resilient fintech systems. His contributions to high-profile projects like pino show attention to edge-case behavior and logging correctness, using creative fixes like representing a silent log level with Infinity. Comfortable across Java, Python, AWS, and CI tooling, he blends hands-on coding with stakeholder-facing process improvement. Colleagues value his pragmatic approach to reducing downtime and shipping secure, well-tested software.
