Network and Cloud Engineer with 10+ years of experience designing, building, and operating distributed cloud-native infrastructure at scale. Proven track record delivering measurable outcomes: from reducing IP provisioning time by 78% through AI-assisted NetDevOps pipelines to building Kubernetes-based platforms for industrial and 5G environments. Hands-on expertise spanning network reliability engineering, cloud-native architecture, and AI-driven automation, with deep knowledge of modern data center networking (Juniper, Cisco, SONiC/OCP, InfiniBand). Certified professional (CCNP, JNCIP x3, GCP PCA & ACE) operating at the intersection of network engineering, cloud infrastructure, and intelligent automation.

Experience

Network Reliability Engineer

IONOS SE
  • Managed network reliability and scaling across three distinct platforms: dedicated/virtual cloud servers (Juniper/Cisco based), IaaS/PaaS (InfiniBand), and IaaS (SONiC/OCP based).
  • Architected and developed new AI-assisted pipelines for network provisioning, communicating with both internal tools and open-source tools (Prometheus, Grafana, NetBox, Ansible). IP Provisioning time has been reduced by 78% with new pipelines.
  • Integrated AI tools in existing workflows: MCP interfaces integrate LLMs with internal IPAM, Inventory Management or Knowledge Base systems, automation using n8n for repetitive tasks.
  • Streamlined cross-team workflows by proposing updated SOPs, standardizing cross-team communication templates, building ticket automation pipelines, reducing coordination overhead and bottlenecks.
October 2025 - Present

Doctoral Researcher

Technische Universität Berlin
  • Architected a microservices-based Digital Twin platform for industrial additive manufacturing pipeline based on Docker and Kubernetes to enable real-time synchronization across 17 distributed nodes.
  • Developed a 5G Core PoC, replacing standard HTTP/2 with DIDComm and Verifiable Credentials for decentralized NF authentication, presented as a candidate architecture in 6G standardization discussions.
  • Designed a decentralized, message-based resource-management framework for K8s, eliminating service downtime and reducing total migration time by up to 77%.
  • Architected a serverless-based 5G Core implementation for private deployments with 31 3GPP procedures.
June 2018 - December 2024

Research Intern & Research Assistant

Telekom Innovation Laboratories (T-Labs) - Deutsche Telekom
  • Developed E2E industrial network prototype for wind parks, using ODL and ONOS controller (Java) to implement multi-tenant network slicing, reducing cost while ensuring QoS for different traffic types.
  • Engineered a 5G mobile edge computing solution to enable service migration across gNodeBs, leveraging SDN-based rerouting (with ONOS SDN controller) to maintain low-latency connectivity for mobile users.
July 2016 - February 2018

Network Engineer

HCM Global Network Operations Center – KDDI Corporation
  • Managed global network services (MPLS VPN, WAN, Satellite). Developed standardized Runbooks and Escalation Protocols for operation engineers to improve the resolving time and service quality.
  • Coordinated with local partners to monitor, resolved issues, performed root cause analysis, maintaining SLA.
  • Co-authored the HCMC KDDI Knowledge Transfer Initiative, mentored junior engineers.
October 2013 - July 2014

System Engineer

Vinahost
  • Engineered a Puppet-based pipeline that reduced server provisioning from days to hours; integrated HAProxy, ModSecurity, and OSSEC to provide high availability and Layer 7 security.
  • Hardened Cisco-based L2 infrastructure across two Tier 3 data centers and standardized IT workflows to ITIL and ISO 9001:2008 frameworks.
May 2012 - September 2013
