Proactively identify, analyse, and resolve performance bottlenecks and technical issues through profiling using tools such as JProfiler and Yourkit, testing, and root cause analysis.
Troubleshoot problems by analysing code and large datasets using AI tools like Github copilot and Linux commands/script as well as logs using Splunk, Datalog and Graphana.
Collaborate with global collaborators and multi-functional teams to ensure data completeness, accuracy, and resilience across network and server environments.
