Load Balancing Research

Mar - Jul 2022 Team Size: 2

Benchmarked 6 IPVS schedulers in a 3-node K8s cluster (GNS3), switched kube-proxy from iptables to IPVS and measured O(1) vs O(n) lookup scaling. Project done with another colleague under guidance of the course coordinator.

Online Tutoring Platform - Quizzes Tutor

Mar - May 2022 Team Size: 6

Working in a six-person team, I built new Java/Spring back-end features for a Quiz Tutoring web platform and wired them into a GitLab CI pipeline that executed Spock unit, Cypress end-to-end and JMeter load tests on every commit. Writing both the code and the test suites let us ship reliable weekly releases without rollbacks.
