DevOps & Platform Engineering

Reliable delivery.
Production-ready infrastructure.

I build and operate Kubernetes platforms, CI/CD pipelines, infrastructure automation, and observability systems. My networking background helps me troubleshoot across application, ingress, DNS, routing, and cluster layers—not only inside one tool.

Professional profile

Practical infrastructure ownership from provisioning to production.

I focus on repeatable environments, safe delivery workflows, useful operational signals, and clear collaboration with development teams.

DevOps Engineer @ B2B Development

2024 — PRESENT
  • Built and operated Kubernetes infrastructure on Hetzner, including a 14-node cluster, using modular Terraform and S3-compatible remote state.
  • Operated Cilium as the eBPF-based CNI for network policy enforcement and cluster network visibility.
  • Designed GitLab CI/CD workflows for React and Go services with traceable image tags, environment configuration, quality gates, and container scanning.
  • Integrated Traefik v3, automatic TLS, PgBouncer, Prometheus, Grafana, and Loki into production application stacks.
  • Automated infrastructure provisioning with Ansible and troubleshot NAT, ingress, DNS, routing, and CNI rollout issues.

Network Engineer

PRIOR EXPERIENCE
  • Designed and maintained LAN/WAN infrastructure, routers, switches, firewalls, and VPN connectivity.
  • Diagnosed layer 2/3 incidents involving routing, NAT, segmentation, and DNS.
  • Built foundations in TCP/IP, BGP/OSPF, VLANs, and systematic network troubleshooting.

Backend Developer Intern @ IponWeb

2023
  • Containerized backend services and integrated them into CI/CD workflows.
  • Worked with PostgreSQL query optimization and asynchronous task processing.
Selected work

Relevant projects, described in operational terms.

01 / PLATFORM

14-node Kubernetes environment on Hetzner

Terraform-managed infrastructure with Cilium/eBPF networking, Traefik ingress, TLS, and remote state.

Result: repeatable infrastructure and clearer network visibility
02 / OBSERVABILITY

Production metrics and centralized logs

Prometheus, Grafana, and Loki integrated with persistent storage and ingress for operational troubleshooting.

Result: shared production signals for diagnosis
03 / DELIVERY

Reusable GitLab CI/CD workflows

Build, test, scan, publish, and deploy stages using Trivy, SonarQube, dynamic tags, and scoped configuration.

Result: consistent delivery across services
04 / AUTOMATION

Infrastructure provisioning with Ansible

Idempotent roles that configure a production web stack from a clean server.

Result: setup reduced from roughly one hour to under five minutes
Technical stack

Focused expertise with broad operational coverage.
