Drove the strategic migration from Nexus to JFrog Artifactory, concurrently designing efficiency projects to improve platform performance and financial control. Architected and scaled Kubernetes-based, data-centric applications, ensuring cross-datacenter production readiness with fault-tolerant, scalable solutions. Managed cloud and on-prem migrations, deploying services and infrastructure using AWS to enhance platform flexibility and availability. Implemented DevSecOps maturity by integrating Snyk and GitHub Advanced Security (GHAS) into CI/CD pipelines, automatically reducing code vulnerabilities by 35%. Boosted cross-functional teams (Dev, ML, QA) velocity by serving as the L1/L2 domain expert on the SDLC stack (K8s, CI/CD), proactively resolving 5–8 critical technical blockers daily.

#eBay Classifieds Group has merged with Adevinta as of July 2021 Managed mission-critical infrastructure, including a GitHub Enterprise server supporting 1,500+ developers and 300+ organizations, guaranteeing high availability and security at scale. Orchestrated a major multi-cloud migration of multiple Dockerized Jenkins instances from OpenStack to a GCP-based Kubernetes cluster, substantially boosting system availability and realizing operational cost savings. Boosted CI/CD efficiency by 15% by developing and configuring GitHub Actions self-hosted runners to meet increased development demands.

Implemented the ELK stack (Elasticsearch, Logstash, Kibana) and Grafana with Graphite for centralized logging and metrics visualization. Created 10+ monitoring dashboards to accelerate self-service troubleshooting and observability for cross-functional development teams. Developed and maintained automated CI/CD pipelines using Jenkins, significantly enhancing deployment efficiency and reducing errors. Actively managed and optimized AWS cloud infrastructure (EC2, S3, RDS), including tasks such as backups, patches, and scaling to ensure smooth operation and availability.

Review and Investigation of Orchestration Frameworks for Multi-Cloud Environment. As part of my Master's project at Wunder Carpool, I conducted an in-depth strategic review of critical container orchestration frameworks in a multi-cloud context. This investigation was essential for determining the company's technical path toward scalable, future-proof infrastructure. My work involved extensive evaluation and hands-on testing of Docker Swarm, Kubernetes, and Mesos/DCOS on both AWS and DigitalOcean platforms. I focused specifically on how to successfully integrate and manage these frameworks in diverse cloud environments. The key outcome was the development of a comprehensive Decision Matrix. This matrix provided the organization with an objective, data-driven framework for selecting the most suitable container orchestration tool based on specific project requirements, reducing decision-making time and minimizing future migration risks.

Tested and identified bugs in mobile applications using analytics tools such as Localytics and Periscope, collaborating with developers to implement fixes. Conducted a Decision-Matrix based evaluation of container orchestration tools (Docker Swarm, Kubernetes, Mesos, DCOS) on AWS and DigitalOcean, aiding in the selection of the best tool for project requirements. Gained practical knowledge in evaluating and implementing containerized solutions to enhance development workflows and operational efficiency.
