At Digital Habits, I performed full-cycle performance testing of banking backend systems, including Private Banking / PPRB and EFS, as well as services integrating generative AI. I designed workloads and ran tests at up to 2000 TPS.
I developed and maintained Apache JMeter scripts, analyzed application logs and infrastructure metrics, and prepared performance reports and recommendations. I also monitored systems in OpenShift environments with Grafana, Prometheus, and VictoriaMetrics.
For REST and gRPC load testing, I developed and maintained Java and Spring Boot service stubs with HTTPS support, configurable delays, and response scenarios. I also assessed capacity and resource needs for target TPS levels.
Previously, I tested SmartPay payment services across regular releases, with workloads up to 400 TPS. I created JMeter scenarios, ran maximum-performance, endurance, and fault-tolerance tests, and developed Java/Sbermock REST/JSON stubs and test data using Java and SQL.
